help, msn voice chat doesn't work when using a gateway?

I am using archlinux as a gateway to sharing Internet access (Comcast cable). All packages are updated. The following is my /etc/conf.d/iptables. The Internet works but currently I found the MSN voice chat doesn't work.

Anyway to make it works? Thanks.

Re: help, msn voice chat doesn't work when using a gateway?

You have to forward the ports msn is using.

The main idea: The one you are chatting with wants to enable a connection to you and knocks on your gateway on a special port. Since your gateway doesn't know to which this port and this request belongs he says sorry no service available.
But when you forward this port to the client-ip you are using to chat it should work. Look for port and forwarding on google and you should find some useful stuff
