Port Forwarding Problem

[#1]

I had my inet installed for the last 3 weeks, but have only been using it for 3 days, I have used several clients installed but are  saying that theres a problem with the listening port, have tried to setup through my Thomson router using Portforward.com tips, followed it to the letter but will not let me put my ip adress in, it stops after 5 characters, does anyone think that theres a problem with my router or is it just me, This has been doing my head in, I'm getting no speeds because of it. Can anybody help me????

Welcome to the forum ScottieBoi
Can you give a bit more of a description of what you are trying to do?
I.e what software are you using, why are you trying to forward ports and what to you mean by getting no speeds

Sounds suspiciously to me like you're trying to enter an IP address into a field that expects a port number?
