I have some real and some fake IPs on the inside. The real IP machines are working just fine getting to the outside world but the fake ones are having problems. I am running natd (-s -u -m -n external_ethernet) and when I slap in the ipfw rule of ipfw add divert natd all from any to any via fxp0 my fake IPs work but the real IPs stop. Removing the line switches which ones work. I had thought perhaps a divert line of something like ipfw add divert natd all from 10.0.0.0/8 to any via fxp0 amight only divert the packets from the inside fake IP machines but it doesnt work so Im guessing that I am missing something. Anyone have any thoughts? thanks -- Steve Heistand heistand@heistand.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
