Need HELP!

[kgbsd]

I'm trying to transfer some files through a messaging client like msn messenger. It keeps failing saying to contact the administrator. We have private addressing here so I know that is a problem. I have configured the

cisco router to map a static outside IP to my inside IP, but that didn't help either. We are running NAT on the router. I am assuming some ports need to be opened.. Also, I would like to make online gaming available to some people as well and I believe this won't work behind NAT without changes either. Any help? THANKS!

Hi,

without describing your network topology and "copy & past" your router

config, nobody can help you.

When you do so, the community can get an idea what possibly is wrong.
