Windows Messenger and Smoothwall

Pete Preston · 09-07-2002, 04:35 PM

Hi
I wonder if anyone can help me reolve the following problem. I have two computers running xp that access the internet via a smoothwall box. I now need to use the windows messanger program with a webcam but have found that I can only get it to work with the computers behind the firewall. I seem to be able to get it to work with text but not with the cam. I am fairly sure it is a security feature within smoothwall but do not know where to look to get messenger to work. Has anyone else experienced this or know how to resolve this.
kind regards
Pete

IIRC voice etc use different ports from the "usual" stuff.
Did you Google the net for the ports? Did you try logging DROPped packets on the fw?

Code:

Feature Outbound  Port Inbound Port
Text chatting 80 (TCP) 80 (TCP
Voice– PC to PC 6901 (TCP/UDP) 6901 (TCP/UDP
Voice– PC to Phone 6801 (UDP) 6901 (TCP/UDP
              2001-2120 (UDP – dynamic) 6801 (UDP)
              6901 (TCP/UDP) 2001-2120 (UDP – dynamic
              7801-7825 (TCP – dynamic
