I don't think there is much special, you just need to keep some
ports open.

There are the tcp ports ircd listens on, ussualy 6667, as defined
in the P-lines.  There is also an UDP port, also ussually 6667,
and it's defined in the M-line.

It requires the resolver to work, so udp port 53 should also be
available.

For authenication ircd (iauth) will make atleast a connection to
port 113.  If you set it up to detect socks also to port 1080.

For the rest you probably want to rate limit or block other
traffic.

Did I forget something?
