Emerge shorewall, read the docs, especially the comments in its config files and set it up. Once you understand how it works, the setup is easy. Then let /etc/ppp/ip-up bring it up and /etc/ppp/ip-down bring it down. In your simple setup, just deny everything from outside and allow everything from inside. Though a dedicated firewall is much better for anything larger, you can get away with setting it up on your connecting box.
