I can’t seem to get virtual server (port forwarding) working on our cheap PTI PAE-CE84 ADSL modem/router. I’m trying to set up remote desktop over the internet. It shows the correct ports being forwarded but when I try them it simply doesn’t work. I think it may be a problem with the firmware as this is a very cheap router but I’ve tried what I believe to be the latest version from here:
I’ve verified the correct ports are opened on our server's built in software firewall by using remote desktop locally. This is why I believe it’s the port forwarding issue on the router. I tried putting the server under DMZ just to test and that didn’t work either. Could it be anything else? If it’s definitely the router then I’ll ask another question to find it’s replacement.
