Box # 1 gateway device is eth1
Box # 2 gateway is 192.168.100.1
on box 1
in /etc/rc.local at the end of the file
ipchains -P forward DENY
ipchains -A forward -i eth1 -j MASQ
echo 1 > /proc/sys/net/ipv4/ip_forward
Then either do the horrid reboot or type those commands in a
terminal as root on box 1
Now go surf on netscape from box 2 in relative safety.
You can get firewall scripts that lock down box 1 from several
sources--others on the list know where they are, but this will
get you started.
