More Info:

It seems as if the firewall was pierced using ports 0, 3, 6 and 8.

compressnet       3/udp    Compression Process

#                 6/tcp    Unassigned

#                 8/tcp    Unassigned
#                 8/udp    Unassigned

None of these ports are live in /etc/services or inetd.conf.

So how did it happen?

Etherboy reported lots of Appletalk, but that isn't compiled into the
kernel..
