Absolutely! Why should we spend $200 on something we can build in 36 hours
of work!?

Use the DNS settings given you by your ISP, use your Linux box address as
the gateway, make sure your ipchains allow all for your internal network,
also allow inbound from you ISP address for the services you want to use,
and deny all else (that's an important step, default is to allow all). Order
is important (like order allow,deny - not deny,allow). Make sure you insmod
any *masq modules you want to allow like icqmasq for internet chat and
ftpmasq for ftp. Oh and turn on IP-forwarding on the windows box. I could
give you specifics if I was at home.
