To tell the truth, it never occurred to me to try. But yes, I can see how this might be made to work. > But realisticly it would probably be better to segregate the two. Exactly my point. Actually this sounds like an interesting project (NATting with one interface), but maybe he's more interested in "getting the network up" than in "having an interesting project." Depends on his priorities... For an ordinary 10baseT ethernet card, I pay something like $10 US. To me, that's a reasonable price to pay for simplifying my life. -- Chris Hill chris@monochrome.org [1] Bus error netscape To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
