Port forwarding on WRT54GS

    I have maintain a network that uses a Linksys WRT54GS with one computer using a wired port and one computer using the wireless service it provides. Both computers are set to automatically recieve IP addresses from the router. The computer that is wired to a port on the router runs Azureus frequently, and for the program to run at its full potential it requires certain ports to be open. I set up Port Forwarding on the router to forward a range of those ports to that computer, and everything worked just fine for a while. Then, I don't know exactly when, but suddenly, Azureus started giving me errors about it not being able to get through to those ports. I went and checked, and the IP addresses of the computers had changed (probably due to a recent power outage and the router reassigning IP addresses), so I changed the Port Forwarding settings accordingly and saved the settings. However, this did not fix the problem as Azureus still gives me the same error messages and tells me that the ports are not open.

    Any suggestions here?

    I am not familiar with the program you are using but as far as port forwarding, Ill try and help.

    In your routers setup page there is a section that you can use to enable or disable DHCP, you can Disable it and in your computers TCP/IP preferences manually assign the IP it had when it was working (example: and subnet then go to port forwarding page in the router and set the same IP that you manually assigned your computer ( make sure you have a check in the Enable box.

    Hope this helps.

    The port forwarding was working when it was assigned, but it is now Is there any way that I can disable DHCP for only one computer? Or will I have to disable it at the router and manually set the IP addresses of both computers?

    Try it.
    Diable DHCP and manually assign IP's on both computers. Remember to assign the IP that was working
