Right now the tun0 interface gets configured from my ISP's DHCP server. And what options in rc.conf are overlapping? Don't I need both "ENABLE_GATEWAY" and "PPP_NAT"? I would suspect that maybe "PPP_NAT" in rc.conf and "enable ppp nat" in ppp.conf are overlapping, but not the listed options from rc.conf? I don't have access to a FreeBSD machine from here, but I'll try "man ipconfig" when I do. I tried to look it up trough the FreeBSD site tough, and it didn't find anything called ipconfig...? - IT To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
