[NTLUG:Discuss] iptables Firewall for one?

[Dan Carlson]

For ipchains I use the following rules to masq my local network, but
disable access to the outside for one of the systems:

-A forward -s 192.168.1.6/32 -d 0/0 -j REJECT
-A forward -s 192.168.1.0/24 -d 0/0 -j MASQ

The syntax will likely be similar but different for iptables.
