I have a WZR-HP-300NH router with DD-WRT firmware.
I can get port forwarding to work for RDP (Port 3389) to my windows server, but I can't get port 80 or any other ports to forward to my Ubuntu server. I verified that the firewall on Ubuntu server is disabled. also, as a test, I opened up port 80 to my windows server just fine.
Can you think of a reason why port forwarding to my ubuntu server just won't work? I had it working when I was on 10.10 but for some reason, it's not working on 11.04.
Thanks for your ideas on this!
