> redirect_port tcp 192.168.100.D:80 80 OK, I'll give that a shot. I should point out for the archives that the D above refers to a random number (I didn't want to use real network numbers). Now, that still leaves two issues - how does traffic for A.B.C.D "know" to go to the firewall (ie, do I use a cname, static arp, virtual ip?) and what if I have more than one web server behind the firewall? Sorry if I'm missing something obvious.
