Hi, I'm with Bell mobility, i have few programs that host a tcp socket and are reachable from any lan network whenever I use Wifi or VPN connections but is there any way to get the data plan connection to have incoming connections. I've tried a whole bunch of ports? Anyone knows a way around this issue?
Would be good to be able to host our own mini website on the phone or reach it with Pocket Controller.
If your device gets a public IP for wireless APN, you should be able to connect to sockets bound to this IP. If you get a private IP, then you can only connect from within the same subnet.
It depends on your data plan ... and your operator.
Some operators block TCP/IP ports below 5000.
If you subscribed a business data plan, it might work ... Just because of business tools you may need (VPNs, SSH connections, remote desktop, ... ).
My advice, connect your phone to your PC as a modem and use any tools to check open ports (try ShieldsUp from grc.com http://www.grc.com/)
Hope it helps.

i got usb wlan adapter. it's ip is 192.168.1.130.
the lan adapter in my pc has 192.168.1.84 ip.
all computers on my local wired network has 192.168.1.* addresses and 255.255.255.0 subnet.
i fixed the IP of SD sandisk wifi adapter on my mda compact to 192.168.1.131.
Usb adapter is in peer-to-peer (ad-hoc) mode and i normaly connect with ppc to it. i got 80-100% signal all the time.
the problem/question #1: why i cant ping from ppc to PC ? firewall turned off.
#2 - if i could ping it, would i be able to ping all the other ip's on my wired network?
#3 - if i could be able to ping all of those computers, how should i set-up a workgroup on ppc and be able to map network drives through wlan link?
#4 - if i would be able to map the drive over wifi link, would i be able to add mine 20.000 mp3s to the pocketmusic's playlist and play them wirelessly?
thanks in advance!
And when i ping from PPC - i see on pc that "received" packets are raising -
ie. now it shows 12 packets received, when i run ping on ppc to pc, the
number increases to 16 (4 pings!) but all are time-outed....
And if the IP on both sides are set to "automaticly", they got assigned
169.254.*.* IP's. Then the ping goes through correctly but i can't still
access the network. The network bridge between LAN and WLAN connection only
made things worser, making my internet connection unusuable (DSL through the
same LAN connection) so i deleted the bridge. Now - ping is going but i
still cant map my pc's drive.... what could be the problem...
Same problem
Dakky,
I have the exact same problem. I bought a Netgear WG111 Wireless USB dongle. I created an ad-hoc network, connected to it but can't connect to the internet or browse my shared. On my desktop the sent packet go up but not the recieved.
Are we both being stupid, can't you connect your PPC to your PC using an ad-hoc network? I have now tried to connect with two different desktops to my XDA and a friends XDA IIs running WM5 to my desktop but had no success. I can connect to an access point and browse file/internet no problem.
I have an XDA EXEC and run XP Pro on desktop.
I've got similar problem. I have Linksys Wireless-G usb network adapter, i assign same class IP adresses (192.168.2.1, 192.168.2.2, mask 255.255.255.0) the wifi connects in ad-hoc modebut how can sync over wifi ?, if I am able to sync over wify i will be able to use my pc's internet connection wich is a lot faster than any gprs/edge
I don't think you can network in this way - basically you have a bunch of clients but no 'server' I think you need a wireless hub (with Internet connection in there somewhere) in there somewhere.
If you do a search on microsoft web site ther is some info about using a PC as an internet share for other PCs but you have to use a very specific IP address rnge for this and set the share PC up in a certain way
MS Activesync (i'm using 4.5) does not support forwarding of UDP packets to the handset from the network. So far as I can tell it doesnt allow them to come out of the handset to the network either. When I say Network I mean IP Network, not Cellular.
Does anyone know of a way to add this feature to my setup, perhaps a UDP Proxy application that will puck up the packets on the ActiveSync Network adapter and forward them to the internet ? Or maybe something simpler like bypassing Activesync altogether ?
Hopeful,
nid
Are you trying to run any application specially using UDP's? I could access Internet once my ActiveSync is up.
Uh, yes, UDP is requred by the application I am trying to run.

O.k. I've exhausted all the resources I have found on the net to troubleshoot my VPN problems myself so can someone please help me figure out why this isn't working.
I have a VPN set up on my home desktop that I can connect to fine with my laptop (both XP home SP2). When i connect with my Verizon XV8600, the connection is stable, no trouble logging on and no timeouts, but I can't access any of the shares on my desktop. I go to file explorer and try to open a path, same as I do when connected at home via wifi, and I get "The network path was not found" and "Network resource cannot be found or you do not have permission to access the network".
I'm connecting via PPTP, I have tried with my network adapter set to "The Internet" and "Work". Under the advanced tab in connections under the "Select Networks" button I have tried both the "My Work Network" and a new network I set up for the private network selection.
It's just diving me nuts because it connects every time and stays connected, but I can't do jack with it. What am I missing people? Any help would be greatly appreciated, this is the last hurdle to having my phone set up the way I want it.
Firewall?
One area to question would be weather you have a firewall or some type of security agent blocking data access on the VPN port of your laptop. Possible?
many routers also need to be setup to pass vpn

The VPN is set up on my desktop and my laptop connects just fine. The trouble I'm having is getting my phone to connect properly.

I've set up the port forwarding on the router, the phone connects, it even shows up under the network neighborhood on the desktop when it's connected. I just can't seem to access my shared folders.

Which ports did you forward? And which router/firmware do you have?
It's not enough just to forward port 1723 you need to enable the GRE protocol (type 47) also. Without enabling it (GRE protocol) the computer from outside connects, you see it in your logs, but it actually can do nothing.

The router is a linksys wrt54g v8 with firmware 8.00.5, yes pptp-passthrough is enabled.
I did a bit more research on GRE and my particular router and have come away confused. Some sites say it doesn't work at all on the wrt54g, but according to them it shouldn't even work on my laptop. I can stream music from an external ip on my laptop and browse all my shares so it seems like its working to me.
There must be something different about how the phone uses that protocol that the router is screwing up. Most of the forum posts seem to suggest that GRE on a lot of linksys routers is spotty at best. I'm thinking about flashing the router with a third party linux firmware (dd-wrt) that supposedly handle GRE properly. Not sure though, don't wanna risk bricking my router just to connect my phone, which I'll probably do once in a blue moon.
I'm attempting to use a Windows Mobile 6.1 device (HTC Diamond) for a temporary internet connection for my mail server while my broadband is down (BT cancelled my line in error and do not seem to be in any hurry to restore the service!). Initially I'm using the built-in ICS functionality..
While outgoing connections are fine I do not seem to be able to make in incoming connection. At first I thought this was due to ICS not port mapping incoming connections downstream (in a port forwarding DMZ manor) so I moved to the seemingly very good WMWiFiRouter tool and which is much more configurable in such ways, however still no joy. Further investigation using the useful website whatismyipaddress.com suggests that my connection is actually not a true connection but instead proxy'd (assumingly by Vodafone). Is this correct? If so, assumingly it is therefore impossible to make direct incoming IP connections (TCP or UDP) to devices on a mobile operators network (in my case Vodafone)?
All comments welcome!
Thanks, Simon
To reply / follow-up to my own post..
It seems this is due to a problem with Vodafone providing data connections with a private NAT’d IP address that is routed through their proxies for traffic optimization etc, and not the required (publically addressable) public IP address for incoming connections.
Please see my separate post on this wider issue: http://forum.xda-developers.com/showthread.php?t=478741
had a problem kinda like it trying to make a socket connection from 2 3 gprs devices
did'nt work unless both had static ip's which cost extre
but it worked ok if just one of them were not a 3 grps device
like a normal pc or a gprs device from another operator
I have a simple home net using mostly windows vista and 7 computers, some printers, external hd servers for backup storage and cameras in a workgroup static ip setup behind an off the shelf router. i set one of the computers as the vpn server since i dont want to buy a dedicated hardware vpn in a vista ultimate machine thats on 24/7 anyway with an incomming server... with the correct ports forwarded from the router to the vpn host.
my remote vpn laptop connects to the vpn fine and can see the network resources, however, has no internet connection once the vpn is connected. do i have to set the host vpn computer to do some sort of its own dns assignments to the incomming connection? its set for dhcp so i dont know why it would assign a valid IP to an incomming but not any other info.
in other words, on my remote laptop, i can connect to a random wireless internet hotspot and have full internet access. I can then enable vpn and log in to my home network and see all the network resources, however if i try to use an internet browser, there appears to be no internet. if i disconnect the vpn, the internet resumes to work fine and obviously the vpn resources are no longer accessable.
what am i missing? under incomming connection properties general tab, "allow others to make private..." is checked, under users the correct user is selected along with "require all users to secure...", and under networking ipv4 "allow callers to access..." is checked, and assign ip auto using dhcp is checked so I would think it should be working fine at this point, however it doesn list anywhere a gateway or dns to assine to incomming connections, only ip's.
host vpn computer is vista ultimate with static ip behind a retail router also assigned a static ip via my home isp.
the remote laptop is running ubuntu 12. just for kicks and to rule out ubuntu causing some problem, i set my android phone up for vpn use via 4g network, and the same thing happens. connects vpn fine, has local resources, but loses internet.
i also was curious as to having a vpn log in for the existing user account on the vpn host machine... in other words, should i just add the username on the host computer as a vpn client, and log in vpn using those credentials? and will that even work if that account is logged in, or will i have to remember to log out when im on the road to use the vpn connection.
thanks all!
