I have a Zhone router, model number 6218-I4-200-0CL. I'm trying to figure out how to forward a port, but there is no actual "Port Forward" option under the configuration options. There is "Port Trigger" but it doesn't seem like that's the same thing. Would really appreciate some help.

The port has been an exception on the firewalls settings for a while. Turning the firewall off doesn't seem to fix it, either. The port has been an exception on the firewalls settings for a while. Turning the firewall off doesn't seem to fix it, either.

Now I'm having yet another issue--I can't access the configuration page http://192.168.1.1/) at all. Was working earlier, obviously... Now it returns a "This webpage is not available" error. This router is epic fail. Now I'm having yet another issue--I can't access the configuration page (http://192.168.1.1/) at all. Was working earlier, obviously...

I'm sorry, I'm slightly confused--are you saying that I should set up a virtual server in order to forward a port?? I'm sorry, I'm slightly confused--are you saying that I should set up a virtual server in order to forward a port??

Yes, absolutely.

If you want to forward a port in some router is called port forwarding (Netgear) in other one virtual server (Belkin).

Please go to your router configuration, enable NAT and then select Virtual Server.

Enter a name easy to remember in the field Custom Server or you can select some of the already pre-configured proposed if you find what you need.
Then in the field Server IP address put the name of the PC you are trying to forward your port for example 192.168.1.10
Now select the external port start and end (It could be the same value if it is only 1 port) and then enter the internal port start and end.
Do not forget to choose the protocol if it is TCP or UDP or both.
Click Save/Apply and you are done.

Here an example of a possible configuration for:
UltraVNC
192.168.1.(Your PC) 5900 5900 TCP 5900 5900
FTP
192.168.1.(Your PC) 20 21 TCP 20 21
eMule
192.168.1.(Your PC) 63940 63940 UDP 63940 63940
192.168.1.(Your PC) 63930 63930 TCP 63930 63930
