hi ya
there is a gazillion various "howto".... too much ..that gets confusing...
and just as many different fw config tools and more log analysis stuff
http://www.Linux-Sec.net/Firewall
simplified rules ...
- let your cable modem just transfer info to/from cable modem
into your rj45 -- to the firewall/gw
- setup the ( dual NIC ) fw/gw to 192.168.x.y interal ip#
- setup IP-forwarding(kernel option) and
see the ipmasquerading-howto
- almost done ... except for the simple/complicated fw rules
see the various firewall-howto
- iptables for linux-2.4.x
- ipchains for linux-2.2.x
- your firewall/gw machine should only run ipchains nd turn off
all other services ... ( email, web, etc...
- but than you'd need more servers....( a good thing )
- now you need to do nat'ing from your fw... more howtos
have fun linuxing
