MSN Voice Chat

[chinapub]

Hi Everyone,

Has anyone configured the firewall to allow voice chat
using MSN Messenger 5.0

I have a checkpoint firewall-1 and i want
my LAN users to be able to voice chat with others over
the internet. The normal MSN chat works fine, i need
to know what are specific ports that needs to be open
in order to allow voice chat

Appreciate any help on this.

Regards,

Tom

Haven't done that one, but I would start with either contacting MSN chat support or help for MSN chat. Or setup a specific rule (bidirectional) for a test PC going to MSN service Any and watch the log file to see where is dropping. A guess on the ports needed would be H323 related port and tcp/udp high ports. That's what we use for VoIP.
