Subject: How can I configure my = firewall=20 to access voice chat with MSN messenger 6.2?

I have a linux server which is configured as a = router=20 connecting my internal network and the internet.  using the = following=20 iptables rules:
 
iptables -A FORWARD -i eth0 -o eth1 = -m state=20 --state ESTABLISHED,RELATED -j ACCEPT
iptables -A FORWARD = -i eth1=20 -o eth0 -j ACCEPT
iptables -A FORWARD -j = LOG
iptables -t nat -A POSTROUTING -o eth0 -j=20 MASQUERADE
 
where eth0 is the netword adapter linking to the = internet=20 and the eth1 is the adapter linking to the internal = network.
It seems the network works quite well, except for = the voice=20 connection of MSN messenger 6.2.  I can't either initial a voice = chat or=20 accept a voice chat.
 
I've got absolutely no idea how to make it = work.  Any=20 ideas?
