MSN, IPTABLES and NAT

[Ragnar Wiencke]

Hi there.   I installed a Linux box as a router firewall for my home adsl connection. We use MSN on both win and mac boxes and that works just fine until we try to use voice conversation or netmeeting vith video, there are communcation problems. I used it before using the linux router so I know it worked. Also I am able to recieve files but cannot send files through MSN.   Any solution anyone?   Looking forward to here from you. Thanks in advance, Ragnar W.
