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?

N1 Oddball Network Access Issue

Hi All,
My N1 has successfully gone onto multiple networks & the web okay. However I am having an issue I haven't been able to solve with my N1 at work.
At work, we access the internet through a VSAT satellite internet service, MTN. The satellite signal is sent to an iDirect router, then a Cisco 1800 Series switch which acts as the DHCP server and allows access via multiple static IP routers around our workboat.
My N1 can see the Cisco IP address (192.168.1.254) & the page requests the Login & password. So I know the N1 is getting past the routers & seeing the Cisco switch.
However, I cannot access any webpages & I do not know why. If I'm getting into the network why am I not seeing the internet? I can do the same thing with different laptops & access the internet successfully so I'm stumped.
Thanks for your time.
Phil

anyone?? Any ideas?

Wi-Fi router

All
I have my htc setup to both internet sharing and Wi-Fi connection on my work PC with a lan connection. On both of these connections e.g. wired USB and wireless i can get the internet for about 3 minutes then it stops working. Is there some sort of block? I did see a while back that the WiFi app has no restrictions...
Any help would be superb.
Cheers
Baker0

Thats a little odd, there is certainly no block and I have had the wifi router running for a good 30-40 minutes without failing.
what part is failing, is the phone no longer running the wifi router, or is the pc no longer getting internet on that network connection?
If you need help on how to find this info just reply and I can walk you through some more diagnostic steps.

The phone is still running just the internet stops on the machine. I have to stop the wi fi on the phone then start again then connect. I think it might be t-mobile but the internet on the phone is fine

are you in the uk?
if you connect your laptop to the phone via the wifi router you should be able to right click the network logo, click on status and view the wifi network info, it should tell you in there if it has internet access on that network connection.
If you try this again and when it fails check this status window and see if windows is seeing an internet connection or not?
when the net fails again try and visit http://72.14.203.100/ (this should be the google homepage) if you see google then there is a dns problem if it still says network timeout or failed to connect or something like that then we will have to dig further.

LOL thanks for your help. I am in the UK. ive been working in IT for the last 12 years and I know and have done the test, its not the machine it has something to do with the phone or t-mobile network

Sorry to hijack your thread a little, but I'm on the T-Mobile Network in the UK too (except I'm using a Touch Pro with a custom ROM), and although I can make connections from the PC to websites using the IP address, the DNS isn't working so I can't resolve domain names.
Any ideas?
Cheers,
Steve.

It must be the phone then since I do use wifi router, I am on t-mobile and in the UK and I do not experience this :S
I seem to be saying this more and more but maybe you should try a hard reset and see if that fixes the problem?

This is likely an issue with the way your machine has been setup to connect to the wifi network. Try visting the properties of the network and vieing the dns settings for the tcp/ipv4, It should be set as Obtain DNS server addresses automatically. If it is set like this then try setting it too 8.8.8.8 and 8.8.4.4 these are googles, dns servers if this works for you then you could stick with this or do some further digging as to why you are not getting the dns server addresses automatically like you should be.

Setting the DNS entries to Google's makes it work, but attempting to get the DNS Server's automatically leaves me with no ability to resolve domain names. How strange?
Thanks for the workaround, not sure where to start looking to fix it properly.
Cheers,
Steve.

Hey guys,
I am new to this wifi router thing and got the following questions:
1. To be able to use it, you must have data connection with your provider. Am I right?
2. By any chance, can I use this system by using a sim taken out of a prepaid mobile broadband dongle and inserted into my device (htc touch HD)?
3. Once I get connected can I surf the internet/check emails etc from within the device itself without the need to use a laptop?
Please don't mind these basic stupid questions.
cheers

Has anyone tried setting up a VPN connection on their Note?

From my desktop i am using BeeVPN and would love to have my phone connection using the VPN protocol protecting my traffic on my phone as well.
So now i am hoping someone here are using either beevpn or a similar service and have setup a secure vpn on their note and would share their experience in doing so?

I've setup a VPN to my home using Windows 7's built in VPN server. I used Dyndns to sort out the physical IP address to my home (since I don't have a static IP) and then set up the port forwarding on my router to forward VPN connections to the PC I have running the VPN service.
Works like a charm (PPTP protocol being used.)

I have openvpn on my XP home machine and also on my (rooted) note. It is a bit fiddly to get the note's internet traffic routing via the home XP box - that does not happen by default on an openvpn connection, you have to set it up in the openvpn server config file. Should then be OK but unfortunately, pushing the default gateway doesn't seem to work on Android in practice. The openvpn client on the note has a workaround for this - a menu option to "fix DNS problems" which does the job after the VPN is established.
I use this method for any stuff I do on public wifi other than basic web surfing where I have no security concerns. So, banking, utilities etc. all goes over VPN. I also use it when I need to present my home IP address rather than thet of the connection I'm currently on: eg. for watching UK TV streams whilst outwith UK, and for remote access to 3rd party systems that sit behind firewalls which allow my static home IP through but nothing else).
Connecting to the VPN from public wifi/3G is very easy (once I've woken the XP box with Wake on LAN). The only real downside is that your download speed over the VPN in this configuration is limited to the UPLOAD speed of your home broadband. I get 800Kbps which is sufficient for decent video streaming (skygo/TVcatchup).
The other major benefit of VPN is that you can remotely access your home PC's and services on them via internal ip addreses without having to open up ports on your router on the WAN interface.

I've had a Vpn set up on my note for about 4 months now with no problems.
I use vpnaccounts.com as the server very easy and simple to setup.
I just wish the Vpn would work using my data connection and not just Wifi but we can't have everything!

I'm located in Brazil and also use vpnaccounts.com on my laptop, pc, Galaxy Note and Nexus S. The server I connect to is in Dallas Tx.
I also use the 1 VPN app which gives you 1 click logon.
Everything works great!

Yes but don't you have to enter your VPN password every time you want to turn on the VPN?
I can't find a way to keep the password remembered by the device.

(Solved) [Q] Android devices connects to wifi but no internet

I have three Android devices and two laptops, all of which I have been using on my home wifi network for years with only minor issues now and again. All of which I have been able to resolve. Two of the Android devices are phones and are rooted with custom roms and one is an unrooted Nexus 7.
Sunday, the 6th of April (yesterday) all 3 of the Android devices lost internet connectivity spontaneously but both laptops still access the internet with no problems over wifi. I was not doing anything with the network or any of the 3 devices. The Android devices all still connect to the wifi and they can all access all the other devices on the home network. I can ping my phone from my laptop and I can ping my laptop from the phone. I can access the files on my phone using AirDroid. I have reset every device on the network including the wifi access point and the cable modem. I called my ISP and they are saying that it might be due to the fact that my cable modem has reached "End of Life" and does not support newer Docsis 3.0 technology which for some reason now precludes Android devices from accessing the internet. I don't buy it. I read up briefly on Docsis 3.0 and it is supposed to be backward compatible with Docsis 1.0 and 2.0. I have not had a chance to see if my phone or the other devices will connect to the internet through other wifi networks but I suspect they will. My phone does connect through the 3g network.
Anybody having this issue and if so have you found a fix? My only solution at this point is to buy a newer cable modem that supports Docsis 3.0. It's not all that expensive but I don't want to buy one if I can't confirm that is the problem. The one I have seems to be working fine with the laptops and was working fine with the Android devices before it quit working. If that is the problem.
If anybody has any suggestions as to how I might test this I would be grateful.

Do you have a terminal app? Start pinging your router then 8.8.8.8. Then if you can ping Google, then it is something else.
Sent from my Nexus 5 using xda app-developers app

That did the trick. At least for now.

Dude, you nailed it. I pinged google and that didn't work and when I pinged the IP it worked. I also was able to ping that 8.8.8.8 ip. I knew then it had to be a DNS issue.
I then set my IP on the phone to static and then I used the Google dns server IPs 8.8.8.8 and 8.8.4.4 as my DNS servers and Bingo, it worked. Why was it working before? What changed overnight? And why did it occur to all three Android devices at the same time. Up until now I had been using DHCP and everything worked fine. I even went for a walk around the block and found a couple of unsecured wifi networks and connected to them and subsequently the internet. But when I got home and connected to my network, no joy. However, as stated in the OP, our wireless laptops work just fine. Maybe Comcast is sending out the wrong DNS IP or they just somehow no longer support Android???

I am having this exact same problem. My laptop connects to wifi and my desktop, ps3, and TV via Ethernet but all of a sudden about an hour ago my Nexus 5 and Nexus 7 can no longer access the internet. They are connected to the network however the signal indicators in the quick settings is orange and I can't access the internet.
Could you tell me exactly what you did to fix this as I am not good with networking type stuff at all...you mention pinging and DNS servers and I have no clue what you're talking about.
BTW I have AT&T U-Verse.
EDIT: I ping'd google in my phones terminal and it didn't work....I ping'd my router and that worked(I think it did anyway...it kept pinging and I had to close terminal to stop it)
I ping'd 8.8.8.8 and got Destination Net Unreachable.

I don't know what AT&T U-Verse is but the problem I had was that for some reason my Android devices would no longer access anything outside my home network. I used a terminal app that I have on my phone and I was able to ping 8.8.8.8 which I understand is one of Google's DNS servers. DNS stands for (Domain Name Service) which allows us humans to type in meaningful names in a browser rather than the IP address. If you can enter this http://74.125.224.72/ into your browser on your Android device you should get to Google. If that works then you need to point your device to a DNS other than the one assigned by your ISP. I just used 8.8.8.8 and that solved my problem. You can also change the DNS server in your gateway device, whatever it happens to be, and that would fix the problem as well. That is assuming you can reach Google using the IP address I have mentioned previously.
There should be all sorts of tutorials and suggestions regarding how you can make the necessary changes. It all depends on your device and network appliances.
