Dynamic DNS (DDNS) for Pocket PC!!! - Networking

Hello!
I am looking for a Dynamic DNS updating software similar to the ones for PC. I found one made by TZO found here: http://www.tzo.com/index.html However I already have a free DDNS service from www.dyndns.com and I want to use that service on Pocket PC's running Windows Mobile 5. Is there any type of software out there that can do this? I primarily need it to perform VNC tasks on multiple mobile phones. Thanks!

hi
not sure about any programs to do this, but if you could how would you connect to the phone? via GPRS/3G, wifi ?
just tested and you cant ping a PPC thats on GPRS/3G from the internet, might beable to if your on the same network but i dont think you could, most ddns clients i know of use the internet ip which is different to the PPC address
if wifi then the ports would need to be forwarded from the router to the PPC unless is on your own wifi network then you would be better of giving them all there own ip
you could get them to connect to a vpn when you need to connect to them, that might allow to connect to them, but not 100% sure

VPN won't work with a 10.x.x.x network

Hi,
I have a little problem that I am sure there must be an easy solution to!
I have set up a VPN on my Universal to connect to work. The problem is that my work's VPN server allocates me an ip address in the 10.x.x.x address range. All servers that I need to access behind the VPN have addresses in this range as well. Unfortunately, my ISP (T-Mobile UK), also allocates an address in the same range. Therefore, whenever I try to acccess a server at work, WM5 suffers confusion since it doesn't know whether to route the message through the VPN or directly out to the internet through the cellular modem.
I have been able to verify that the VPN thing works if my work network was on a different network address since initially, I was unable to VPN into my PC at home for the reason described above. I changed the ip addresses of all machines on my home network and now everything works fine at home.
Unfortuantely, I am unlikely to convince the IT people at work to change the address of all their machines. Similarly, I don't think I will have much success with T-Mobile and so is there anything I can change at my end to avoid this problem?
Thanks in advance for any help.

Narrowing the ip address may help, eg 10.0.0.1 is different to 10.1.0.1.
are you using this over wifi or gprs? if the phone provider is involved, I assume its gprs.
you could try and esablish your ip address as fixed rather than part of the pool, so the it guys assign a range for remote connections as say 10.0.0.100 to 10.0.0.150 as remote dial in connections, thus giving you a separate number.
the best way though I would have thought is for you to a fixed ip address known to you and the servers, and then hard type the ip address as your vpn settings, then establish that ip address as part of the exceptions settings.
in order to use exceptions though you have to know the range, or the exact ip address you will be assigned, and must be different to your telco.
not much of a solution, just some suggested areas to look at.
cheers

hi guys, just out of curiosity what software are you using for VPN? on my laptop my company has installed cisco vpn, does it need to be a cisco vpn for wm5?? :?
From bad to worse...
Thanks for the reply Simon.
Unfortunately, I just went to try out some of your ideas and discovered that I can't get the VPN to connect at all now. It used to connect OK but then have routing problems whenever I tried to access anything. And my home VPN worked perfectly. Now, I can connect to neither.
I simply switched over to an O2 sim and with minimal configuration changes could verify that my setup still works OK and so it must be something to do with T-Mobile blocking ports. They weren't blocked yesterday!!!
Yesterday I "upgraded" my GPRS account from T-Mobile's Web'N'Walk to Web'N'Walk Professional and now I find I have this problem. Is this just a coincidence, or could it be that the Pro version has more severe restrictions than the consumer version?
I have emailed Customer Services to see what they have to say.
I will post back when I get a reply from T-Mobile.
mstar, I am no VPN expert, but for me, using a Windows XP hosted PPTP VPN it works after a fashion (above problems excepted!). I am using the VPN client built into Windows Mobile 5. I think you stand a good chance of getting it working using the built-in client.

I've heard on the grapevine that T-mobile have explicitly refused certain types of traffic on the web-n-walk
VOIP is the biggy...
I was seriously thinking about getting signed up - but no point if IPSEC is a prob, as well as VOIP.
Not sure how they can tell it's Skype traffic :?

An Update
An update on my VPN problem. Yesterday after total failure to get the VPN to connect, I emailed T-Mobile customer services.
Although they have not replied, when I tried it this afternoon I found that it was working again as before even though it had not been working first thing this morining. Of course I have not changed anythng at my end to cause it to break and then start working again (but they all say that, don't they!).
So, I don't know whether this was just a momentary fault, or whether T-Mobile have changed something to re-enable the VPN ports for me. I can now VPN in to my home PC, but the problem connecting to my work VPN with the 10.x.x.x address remains.
So, Sikkutz, depending on the address of the remote network, you may or may not be able to get a VPN to work using T-Mobile's Web'N'Walk.
By the way, my VPNs both use Microsoft's PPTP and not IPSec and so there may be different issues with that protocol.
I have discovered that O2 provides a separate acccess point, vpn.o2.co.uk, that causes a public ip address to be allocated to the device, ie not on the 10.x.x.x network. It would seem that this is designed to address this very problem. Does anyone know if T-Mobile can provide something similar?

There must be a solution
Hi!
I have the same problem with my Qtek 9000 (VPA IV). I can connect to my VPN Gateway but the routing into LAN failed. I get a 10.x.x.x address from Vodafone Germany and my LAN uses 10.98.8.X. :-(
But there must be a solution! My previous Qtek 9010 (VPA III) had the same problem, but it was able to route between the 10.-networks after a firmware-upgrade to version 1.40.01! But I don't no why!
What was changed in firmware to enable routing???
Daniel
i have the same issue aswell, I am reluctant to change the IP range of my machines as that usually causes trouble for the servers
Any other ideas?
Thanks
maybe stupid thing, but did you guys try dna forwarding (that is what I use from home office, not on pda to be honest..
Maybe I just did not get your point....
What kind of VPN server do you use? I'am using a Cisco PIX and use a PPTP VPN almost everyday. I can use the 10.1.x.x network at the location the PIX is located (this PIX is directly connected to the 10.1.x.x network).
I can't however use any of the remote offices using 10.2/10.3.x.x etc.
This is becaus of the lack of routing abilities in the PPTP implementation.
With an IPSEC tunnel (additional software needed) the remote offices can be reached without any problems.
I know that some IP implementation disallow routing between a public address and any 10.x address. To solve this you could give your VPN clients an address from a 10.x subnet .
hi sorry been away awhile,
I use the routing and remote admin snapin of Windows server 2003 to manage my VPN, I can connect fine using the phone as a modem with my notebook but as soon as I try accessing any URL/resource on my network it fails, e.g. we have a intranet site on http://servername but it wont open this up.
Any Ideas?

ICS & VPN with WM6

My searches on the web haven't yielded much help or information so I thought I would come to the experts...
I have a Treo 750 that I just "upgraded" to WM6 2 days ago. I noticed that DUN has gone away and was replaced by ICS. After configuring my laptop to use that instead of DUN I connected and was surfing the web. My problem now is VPN. I travel frequently (luckily I'm in the office until Jan.) and regularly used my phone to connect to the corporate network via VPN. I also work with a lot of other companies and have VPN access to their systems as well. Basically now I can open my Cisco VPN client, connect to a VPN gateway, authenticate, get assigned all the appropriate IP information, but cannot communicate on the network. What gives? Is there a solution to this? If not, what the heck was MS thinking when they did this!? My phone is basically useless for one of the major reasons I bought it...
Any help is appreciated!
thanks!
Ok, further searches found that DUN can be added back into WM6 via a cab that was posted here at the XDA forums. I installed it and the DUN service is now visible again. I unpaired by phone and laptop, re-paired, and included DUN. Now when I try to connect, I get the DUN connection box after the bluetooth connection is initiated but when I click DIAL I get the DIALING... prompt, followed by Error 678: The remote computer did not respond.
Anybody get this working on a Treo 750? Thoughts, ideas suggestions?
What is the ip address you are getting via the cisco vpn client
It maybe that it is in the same subnet as the ip address assigned to the pc from the wm6 ics. The ICS gives the address 192.168.0.1. and if your Cisco is also giving a 192.168 address then you will have two routes for the 192 address range thus giving you the problem when accessing hosts.
If this is the problem Im pretty sure you can change the address allocated via the ICS using a registry editor. If not you may be able to get work to use a different range for you on the cisco vpn.
Our corporate network is 172.x.x.x so it's nowhere near the 192.168.0.x assigned by the phone. When I look at the route in the VPN client I see 192.0.0.0, 10.0.0.0, and 172.0.0.0 so I am assuming 192 is my laptop, 10 is the phone, and 172 is the corporate network.
I'm guessing NATing is the problem. I've been reading that if I use a different APN (isp.cingular instead of wap.cingular) there is no NATing. I've tried both, and I've tried turning off and on the "force AT&T" proxy setting to no avail.
Tried the DUN cab hack that is floating around for WM6 also. The service is active again and I can also add Modem Link back in and my laptop sees my Treo as a modem but when I dial I get an error stating the remote computer did not respond. I'm guessing along with going from WM5 to WM6 AT&T also updated the radio so the old communications protocols don't work anymore?
Hello Sir,
I have exactly the same problem... I have successfully connected via VPN, however unable to communicate with any devices on that network... Then what is the use of VPN on the phone? I've tried searching online for answers, but no luck... People are having the same problem but no one knows how to solve it... I'll try and trouble shoot this problem more as soon as my exams are done...
Hi
Working successfully for me. I am using Imate jasjam wm6. Pc using cisco client connecting via ics on phone. I have telstra 3g connection tested ok on both telstra.internet (Nated ip) and telstra.extranet (real ip).
You are correct it may be an nat issue. Can you check that your transparent tunnelling is on as follows: right click on your connection entry in cisco client and select modify then transport tab. Check that enable transport tunneling is enabled ipsec over udp(Nat/pat).
The other thing to check is that the cisco vpn server aslo has transport over Nat on as well.
Also are you sure your corporate ip range is 172 or is that the range given by the cisco vpn to clients.
Transport tunneling is on (always was). I'll have to check with our network admin and check on the VPN server setting...I guess as long as I have connectivity back to the office, I don't need it that badly for all the customers I need to connect to at various times.
Yep, positive on the corporate IP. Right now it is 172.28.1.87 and I'm in the office.
Thanks for the help so far. Got any other suggestions on how I can troubleshoot further?
One other thought...should I modify the registry on the phone to assign a different IP address to my laptop? Would that help?
Same Problem
MX. I am having the exact same issue but with Securemote VPN. I've looked through the registry and found the assigned address, but I'm wary of changing anything until I can find some more information.
Anyone out there ever change the DHCP configuration for their phone?
Somewhat related question?
Im attempting to route my connection on my mobile through a laptop acting as a wan bridge, then uplinking it into the router. The issue Im having is that XP and WM6 both use the same IP Block. Ive read and read and cant find much to tell me how to change the WM6 IP BLock to something like 192.168.2.1 rather than the default 192.168.0.1
Does anyone have any pointers? Ive looked through the registry. There MUST be a simple way to change a default.
To clarify my setup, I am using ICS Via USB into a UMPC laptop running XP. The UMPC is set to share that same connection back out over Ethernet. The ethernet runs into my WAN Uplink on the router and then back out via wifi/rj-45
This setup works as I have done it using Wifi with other networks, and I can chose the "Lan3" to share under the advanced settings on the UMPC. The reason I dont just share out via Wifi from the start is that Wifi on my Kaiser and Raphael both make the device to hot to charge, thusly killing the battery within a couple hrs of sharing. If I share via USB , it stays pretty cool and still charges.
Anyone have any pointers?
I have already tried tricking XP into using the Lan on another block but as soon as you try to share the USB lan, it reverts back to the 192.168.0.1
The only way I can imagine is a registry modification or a program change in ICS.
Thanks Much!

accessing network services on pda over the internet (gprs/3g)?

hi,
i have a hd2 and want to run different network services like ftp server oder a vnc server on it.
when i connect to my pda while it is connected to my home network with wlan, everything ist working as expected. eg. i start the ftp server on my pda, and connect to it from my desktop using the ip adress that it has obtained from the dhcp server, also vnc and other services are working fine.
the problems starts when i try to connect to my pda over the cellular data connection gprs/3g. the device establish the connection, i can browse the internet oder use email, everything works as expected. but when i try to access the ip address that the telecom provider has given to my pda, i cant make a connection. i get the ipaddress over tools like vxutil oder pocketdhcp and also try webservices like whatismyip.com, to asure that the ip is correct. but i simply cant connect to the device. its like all ports are closed.
are there any restrictions in the ip stack of the pda for incoming connections or is this a provider firewalling thing? i tried 2 different provider my self an both seems to have this problem.
regards mad
it comes down to which ports your phone company leaves open most don't leave too many open
hi,
thats what i expected too. as far as i can see german t-(in)mobile and eplus seems to block hardcore everything. the main application for me is vnc, i want our customers to be able to connect remotly with the ultra vnc sc tool. so the only way to do this when im at gprs/3g, is to use some kind of repeater software on that is always on and is connected to the internet all the time.
regards mad
where is i canfound related forum like this??

Is it possible to use pocket controller over internet?

Hello everyone
I know that there is an option to use pocket controller through WIFI,
I would like to know if is there any option to connect my device through the internet (HSPDA OR GPRS)? I tried to do it without succsses.
I want to locate my device in some place and to use his camera from my home. - like a hidden camera?
I think pocket controller can be a good software for this but i dont know how connect my device through the internet. Is someone know? Maybe is it possible with other software?
thanks
Ofir
You might be able to do it with http://www.mymobiler.com/ i think you can connect to it via wifi.
Wifi isnt good
I want to do it through internet and not through wireless network...
if your isp don't block the ports used then it's 100% transparent if your device is connected to wifi or 3g/gprs
How can i know if the port is blocked?
Is there specific configuration that do i need to do?
Because i didn`t succssed to connect my device through the internet ip?
there are sites you can google which show you which ports your isp blocks
or you can contact your isp maybe it's even on their site
doesn't matter if your telco don't even have firewall, you still can't connect from the Internet because you cannot see a private IP from outside.
the software must initiate the connection from your phone, so your telco will know where to forward the connection back to your phone, like msn remote assistance.

Remote Desktop Help

So I want to use remote desktop on my TP2 to connect to my laptop at home. I've done all the requirements to allow to use this feature; I've enabled port forwarding in my router settings and I have enabled remote desktop on my laptop's Windows 7 system properties. And on my TP2 I enter my ip address for the "computer" field, my Windows 7 account user name in the "user name" field (I only have 1 account on my laptop and it is admin), and the account password in the "password" field. After all of this, my TP2 will still not connect to my laptop. At this point I am pulling my hair out trying to figure out what I am doing wrong. Can anybody help?
Does your computer has public IP Address?
Yes. I go to www.whatismyip.com and it displays my ip address. I've tried entering this address in the "computer" field as well and nothing.
you'll need to forward port 3389 through any router you may be using (check out portforward.com)
you'll also need to enable RDP connection on the machine through System>Remote.
there are 1001 guides you'll find with a quick google, its not a phone specific thing.
edit: ive previously found that the WM RDP client wont start a 'net connection itself. if you find the same, just do it manually through com manager or check ur mail etc.
Did you forward port 3389 to the internal ip address of your laptop?
Do you have a software firewall on the laptop that may be blocking access?
First try to figure out where the error occurs.
Try to connect to your pc, using an other pc ( from outside )
If it works, it must be a setting in your mobile device.
If pc also doesnt work, it should be a port problem, in that case, try using hamachi..
Oh, and check if you dont have a blocking program, or firewall .. like suggested above
Does my phone need to be connected to wi-fi in order to use remote desktop or will it just use my carrier's data service?

it will use any data connection available, no need to connect to wifi if you have data plan activated.
some tips:
1. you must have NAT (port forwarding) configured in your router
2. If your router has public IP address on WAN port, then point 1. is just sufficient if you are on some routed network, than you need to ask your provider, maybe you will be lucky
2.1. (here are network ranges used as private, only for identification)
from 192.168.0.0 to 192.168.255.255
from 172.16.0.0 to 172.31.255.255
from 10.0.0.0 to 10.255.255.255
3. point 1. specification - enable NAT from WAN port to local IP address of your computer, specific port is TCP 3389. Also is good to make a reservation on DHCP server for this PC.
4. you need to enable remote desktop on your PC
4.1. computer properties - remote desktop setup - and its middle line on remote desktop settings
4.2. click "choose users" and check if your account is listed
Thanks alot to everybody's help! Your advise allowed me to get this things working, I really appreciate it. I had the port open and had remote desktop enabled on my computer but the thing that was killing me was I had the windows firewall on and my ESET Smart Security firewall on as well. Once I disabled them I was able to make the connection. What a head ache those firewalls gave me. I thank you all once again for your assistance.
I want to remotely access my PC from TP2, what software do I need to install on my phone?

The answer depends on what you have available to connect to. Your network (if any exists) and the machine/OS you want to connect to.
If you could let me know the following, I'll see if I can help:
How you machine's connected to the net. (for example, mines something like PC>Router>Cable modem>outside world).
The operating syustem in use on your PC. Specifically please, the edition and version is important to know. Mine's Windows 7 Ultimate, for example.
but, to cut a long story short: if you're not using a home edition of one of the recent windows OSs (XP and later), I'd suggest Remote desktop's the best way to go. There's a .cab knocking around here if you don't already have it on your phone and the PC end's described in the 'Configure Remote Desktop' and 'Configure Your Router' bits of this page: http://www.microsoft.com/windowsxp/using/networking/expert/northrup_03may16.mspx (ignore the other sections, they're not relevant unless you're running IIS)

I have a WIFI Router installed, have a laptop with VISTA ULTIMATE and PC with XP Professional.
I am already able to RD my laptop from my PC.
I want to RDS my laptop from my phone via the same network/WIFI. I think it is pretty simple.
This is what I am doing
I have installed Remote Desktop Mobile
I have connected to WIFI
when I run Remote Desktop Mobile & enter my laptop's name, with username and password and click connect, connecting remains on top and is not connecting it. I am not in any domain, do i have to leave the domain name empty?
if you're not using a domain, leaving it blank's right.
Does it just time out on your phone?
Do you get the same if you try connecting via IP instead of your machine's name?

Your laptop seems to be configured well ( you can access it using the pc )
So it must be a setting in the phone. You sure it is connected to wifi , maybe it stays on 3g ) Or maybe your laptop only allowes 1 ip to connect ( the pc's ip )
I am even able to connect to my laptop over internet as the port 3389 is fwd.
Do I have to configure anything on my phone other than installing that cab file?
Or maybe the cab file I've installed is corrupt or something, can someone please share the cab file?
