Port Forwarding not working in XP


Recommended Posts

I use a wireless router at home, although there is a direct physical connection to my PC. I use port forwarding for online voice and to allow GR hosting. Everything was working fine until recently.

The only system changes that I can identify is a recent update to XP. Anyone out there with XP knows what I'm talking about - apparently, XP needs to be updated about every 3 days or so. Anyway, I'm guessing that the latest update was related to the Blaster virus.

After this update, I can no longer host. I checked my port forwarding settings and they are unchanged and correct. People trying to connect ot my IP get an "Unkown Status" message.

Any ideas?

Do this, and let me know what happens, and we will go from there. Im back from vacation, so there wont be a lengthy wait for a reply.

Unplug the router from your PC.

Go to Start, Run, and type in cmd.

In the command window, type this in :

netsh int ip reset resetlog.txt and hit enter.

It wont give you a completed message, so when the cursor returns, close all proggies, shutdown your PC for 15 seconds, and reboot. Tell me if this clears up your issue.

What this does is this : it resets your TCP/IP stack. With Win9x/ME, to do this you had to rip and reinstall the TCP/IP stack. With XP, the TCP/IP stack is built into the kernel, and only has to be reset.

I reset the IP stack, but now I am not able to connect to the internet. The router is still working, and the connection is good (using it now with my wireless laptop). I am able to ping my laptop via IP, but am not able to use Internet Explorer or Gamespy.

I've searched Microsoft's knowlegebase with no success. Help!

Problem solved!

There was a DNS resolution issue. I was able to compare the ipconfig /all settings between my desktop and the laptop and the Network Properties for the TCP/IP connection were set to "automatic" on the desktop, but hard coded on the laptop.

Changing the desktop properties to match the laptop solved the problem. This, of course, was after modifying the registry, restoring the winsock entries, and a bunch of other stuff. Most of the tech sites that I found suggested re-installling XP.

:( I am also having problems hosting with my wireless ADSL Router.

I have a Desktop PC running XP Pro with a direct connection to the router. My laptop uses wireless. All the usual stuff works, including MSN Voice, but only after enabling DMZ and routing to the desktop PC!!

I run Norton firewall on both PC's, but have even - dangerously - disabled it in an attempt to host.

I can connect with no difficulty to a game hosted elsewhere, but others cannot connect to a game that I host!

I have a dynamic assigned IP from my ISP and router auto-assigned IP's to my PC's.

I'm greatly confused about the 'Network Bridge Autoconfiguration IP Address' as it doesn't correspond with my ISP IP. I've found a reference to the same IP when, unsuccessfully, trying to host a 'TeamSound' or 'Roger Wilco' session.This is the IP that GR says I am hosting on! Is this right? What is it for? Should I disable it?

My network details are:

Microsoft Windows XP [Version 5.1.2600]

If your IP address is assigned dynamically, every time you host, you will need to provide a new IP address.

The IP address on your computers will be the IP address to your router, not to your ISP. If you go to someplace like www.whatismyip.com, you will be able to determine the dynamic IP, which is what others will need to connect to your game.

In order to allow GR or RogerWilco, etc., you will need to set up port forwarding on your router. This will open certain port ranges that allow the software to connect to your machine. Each product/software will have different port forwarding addresses.

Ghost Recon uses 2346-2348

Roger Wilco uses 3782 for client, and 3783 for base

I came across this link: http://www.purenetworks.com/news/pr072903.php

has anyone given it a try?

One of the suggestions I got from another user of the same ADSL Router, was to enable DMZ and route to my desktop PC. Hence the firewall being required. Also, I have found that NAT doesn't block all intrusion attempts.

I've disabled my network bridge as it was only required for a cable network connection. Now my IP is showing as 10.0.0.8.

<_< Correct me if I'm wrong, but is this the basics of what I must do:

Desktop PC (ip 10.0.0.5) - hosting Ghost Recon:

Forward ports 2346-2348 to 10.0.0.5 (both in and out)

Host a game and tell others to connect using my Dynamic IP

Laptop (ip 10.0.0.8) - playing Ghost Recon

Connect to the host using the dynamic IP.

Weird setup, I know, but it fits with what is needed.
