Posted: Fri Jun 08, 2012 14:26 Post subject: Port Forwarding Change Made My Router's Web UI Unreachable
I have a Linksys WRT54G (don't know what version) with six ports forwarded. One of the forwards is for HTTP (80) to a specific server for my personal web site. I added a second server for a game, and the administration UI for the game is also web-based, so I forwarded all incoming port 81 requests to port 80 on that server so I could access the second web site.
The problem started after I decided to change the incoming port forward of 81 to 8008, because 81 is usually reserved for Tor proxies. The change in forwarding for port 8008 worked fine; I can easily view the web site from outside my LAN (I am currently outside it), and all the other port forwards are working properly (HTTP-80, FTP, SSH, etc.).
The issue is that I can now no longer access the web UI for the router from inside OR outside the LAN. I'm currently unable to physically access the router to reset or reboot it, and I don't have SSH access enabled to the router. Is there any history of a problem such as this? Did the change in port numbers somehow mess with the router's web UI? _________________ "Work is the curse of the drinking classes."

I imagine you have a port forward loop possibly.. I would do a 30/30/30 and start over... do each forward until you find which one breaks it.... if you need further help let me know.

What exactly would you think the port forward loop could be? All the forwards were working fine before the change, and they all work fine after the change. The only thing that's broken is accessing the router web interface. _________________ "Work is the curse of the drinking classes."

This would seem a likely cause of the issue if it weren't for the fact that the router's web interface was always accessible (internally on 80 and externally on 8080) before the changes while there were two port forwards (external ports 80 and 81) to two separate servers on the LAN. Plus, the router only forwards requests from outside the LAN, correct?
How exactly would this be the problem after only changing the external forward of 81 to 8008? _________________ "Work is the curse of the drinking classes."
