You may want to open auth too.

Closing service can be done by /etc/inetd and update-rc.d but for your
purpose installing ipchain based firewall may be better.  If this is
gateway machine, you want to install ipmasq package.  To close service,
by ipchain, follow

The script attached is actually for potato ipmasq.  My quick reference
site has same info.
