Date: Wed, 26 Jul 2000 11:31:52 -0400 From: Michael L Artz Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Is it possible to use ipfw without using some sort of NAT? I have a small subset of a class C network for home and want to set up a FreeBSD firewall. I don't want to use any sort of NAT because of its limitations (games, realplayer, etc) and because I have the IPs, so I might as well use them. I have read all of the docs that I could find and all of them say to use NAT .... Another little question ... when setting up a FreeBSD router, can both network cards have the same IP? for example, if I have DSL coming to my house with static IPs 208.208.208.1 - 208.208.208.7, can I set up my FreeBSD machine as a router right at the DSL and have it look to the inside and the outside world that it is 208.208.208.1? I know this is unnecessary for just a router, but I eventually want to set it up with a firewall. Any help would be greatly appreciated. thanks, -Mike slyph@mit.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
