X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 23 Dec 2004 16:55:57 -0000 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.
