In general my advice would be to make your system secure /without/
a firewall. I.e. do not run services that you do not need, and
make the ones you /do/ need only accessible from the LAN, not from
the outside world. Then, you can run a firewall as a double
security. It is dangerous to rely on firewalls only for security
because it so easy to make mistakes with them.
