From: "Julian C. Dunn" To: freebsd-questions@freebsd.org Subject: ip masquerading - such a thing in FreeBSD? Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG This is more a curiousity question than a problem, but I'm hoping someone can give me an answer nonetheless. Is there such a thing as IP masquerading in FreeBSD? Or is it done automatically if I set a machine to be the default gateway for the network? At home I have the typical setup as follows: [dialup] <-- PPP --> [FreeBSD box] <-- ethernet --> [Linux box] and the FreeBSD box is the gateway for the local network. From my Linux box I can already access the outside world, even though (obviously) it doesn't have a real IP. Does this mean FreeBSD is automagically doing IP masquerading? My friend asked me this because he has the same setup, but his gateway box is also a Linux box, and he [thinks he] has to explicitly install masquerading on it. I'm wondering if that is necessary at all, or if he could just set the clients to use the Linux box as a gateway like I did with FreeBSD, and be done with it. - Julian -- Julian C.
