Effective ipfw rules for blocking MSN Messenger ... ?
I just setup a FreeBSD box for a router, so that I could make use of ipfw to block MSN Messenger traffic ... but I'm having a bugger of a time finding a "definitive" list of what needs to be blocked :( MSN Messenger appears to be smart enough to go *around* the usual port 1863 and onto port 80 if it needs to ... Can someone that has successfully done this using ipfw send me a list of rules, since obviously I'm not catching it :( Thanks ... Marc G.

Apparently the best way to accomplish this goal is to block all traffic to and from the MSN boxes, rather than trying to filter by port #. I thought I had a list of those IPs handy, but I can't find it... -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I know this is true for audio and video communications. The standard SIP port is 5060 if that helps.

I think by blocking the SIP port you could stop Messenger from receiving contact presence information and hence, block Messenger.
