AFAIK, you can do it that way, but it is safer if you just run everything through a firewall. now if you don't want to have a server on 24/7, routers are the shit. my sister (knows little about computers) has a ZyXel router/modem, and it works great.. all depends on what you want. --- doug reynolds | the maverick | mav@wastegate.net PGP Public Key Fingerprint: 6E7B 9993 B503 6D45 E33A 2019 26E5 C1DB To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
