I tried >to STFW, but all I got was people trying to sell me >modems. the difference between a modem and a router is that a router is an ethernet switch with a dhcp server and a ADSL modem built in.. where as the modem is just a modem to connect into one computer. basically all the router does is assign each computer a dynamic private ip and NATs all the packets into the DSL connection. if you already have a freebsd box and a hub, pick yourself up another ethernet card (I've had good luck with linksys and dlink- only 20$, I sure you have your preferences), and hook the modem to it. and run ipfw/natd.. why not run it through the hub? main reason is that it is a security hazard. 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
