Im slightly confused hun about your post because Chat Servers can use any port that you assign them, the important details however are:
-The port is entered into the Config file of the chat server program.
-The same port is then also listed in any firewalls, or software protection running that requires opening a port.
-The same port is used for the configuration of the Linksys, and also that the Linksys rules made point to a specific IP address on the LAN.
---Which you can locate by doing:
---Start > Run > type in cmd
---Then say OK
---In the new black box that appears now type ipconfig /all
---Lots of imformation will show up, the IP Address
is what you need to make the rules go to
---**Note: Linksys routers are famous for reassigning new ips upon boot up, so its a good idea to also write down your DNS ---Server IPs
at this time in order to help you set up a static IP on the Computer you plan to host with.

Once these requirements are all met you should have no problem hosting the room
