MSN Messenger / Firewall Rules


I have a linux gateway for a windows network running RedHat 9.

The current firewall setup is the basic one from the Masquerading-HOWTO

The Linux Box has UPnP enabled.

Yet still, I can't get MSN Voice to work....

When I load up MSN it says that it is connecting through a UPnP NAT to the internet and all is well.

Quote:
The actual Real-time Transport Protocol (RTP) streams are sent using dynamically allocated UDP ports in the range of 5004 – 65535. Without a way to open these UDP ports on any firewall in the path dynamically, the streams will fail to reach their destination.
I am guessing that the default firewall rules are blocking this. If so, how would i create a set of rules to enable it, preferably using a script I can easily enable/disable as I would rather not open 60000 ports up just for msn, UDP or otherwise.

Any advice?

In addition, would you suggest any particular firewall configuration.
