Firewalling

OKay! I compiled in the firewalling code on 2.1.44 (patch version) that
I am still using.

I tried various ipfwadm commands that many persons tried to help me with.
None of them escaped syntax errors. Therefore, from `ipfwadm -h` I deduced
the following command:

ipfwadm -F -I quark -a deny -P udp -S 204.178.40.0/21 -D 204.178.47.0/21 137:139
ipfwadm: setsockopt failed: Invalid argument

Do I need new tools?

If so, anybody know where they are? I tried to recompile a 1 year old
version of ipfwadm and it doesn't "understand" some new headers.

Cheers,
DJ
