Did you try using SOCKS4 ?? (You have to enable the app filter on port 1080) It works for ICQ, I can transfer files and make phone calls to the outside world with it, but I never tried with MSN.

I've only been able to use this MSN feature when i used live ip from the ISP (bcos i'm not behind the proxy/firewall probably). But my staff have only been able to use this feature among themselves within the intranet but have not been able to achieve the same with people outside the intranet, that is outside the ISA. The instant messenger service is working fine though only when i used the "client address set" instead of usernames\groupnames when assigning permission to internet usage. Can anyone please help on this. wasiu. A+, MCP+I, MCSE __________________________________________________ Do You Yahoo!? Make international calls for as low as $.04/minute with Yahoo!
