[asterisk-users] NAT router for Linux

[Julien Claassen]

Hello everyone!
   This is my problem: I try to do gtalk, but my asterisk server uses the local 
IP 127.0.0.1 or perhaps the 192.168.*.*.
   Now I've heard, that a NAT router can help there. I was told it's the way 
the windows-world does the trick, when they sit behind a 
router/phonebox/modem. Does anyone know a good software that will do the trick 
on Linux? I'm running Debian Lenny and one important thing: I can't use a GUI 
to configure anything.
   Any help is highly apreciated!
   Kindest regards
           Julien
