masquerading problem

Hi.
I am using a linux box as firewall and router. I'm using iptables.
Everything seems to work just fine... but Windows XP messenger client
does not!
It can't connect and log in and I dont know why. On a different linux
box within the network I can login with a msn client.
I must say that ftp, irc http, etc... everythings works fine... I have
enabled the 1863 (I think) port for msn.

I can't understand what is the misconfiguration I have, because I can
access on a linux box but not on a windows one. I am confused.

Please help me.

to use video and sound msn use dynamics UDP port between 900 and 65535

one solution is to use upnp deamon
