The method you use to get the IP addreses in there is pretty much up to you. I like the /etc/start_if.<interface> method. The interface you want to bind the IP addresses to is probably the Ethernet inferface (xl0) (unless you're doing strange things with loopback (lo0).. and that's up to you :) or I just missed some details). Using IP addresses that end in 0 and 255 gets you a big slap on the wrist where I work hehe. We generally try to avoid them to prevent any headache. Hope I understood everything here correctly. -- Eric Futch New York Connect.Net, Ltd. efutch@nyct.net Technical Support Staff http://www.nyct.net (212) 293-2620 "Bringing New York The Internet Access It Deserves" On Mon, 24 Jan 2000, N.B.
