Howdy,

You still need to set up IP masq/iptables to forward the packets from a
private network address (192.168.X.X).  You can create a simple shell
script to configure it all automatically upon boot.

There is more info available out there than you can imagine, so start
googling with ipmasquerading or iptables, whichever is supported by your
kernel...

Have fun!
