[Hi, COLS gurus! Chef Bodini is using iptables and wants to drop all
incoming connections to ports 0 and 1, so they appear to the baddies
as "stealthed" instead of "closed". We have a solution that works for
TCP but not for UDP.]
I *think* you can still use ipchains with recent kernels, if you
really want to, but you may have to compile some extra code. Using
ipfwadm may be even more complicated. :-)
"-p udp" seems to work for me with Linux 2.6.26-1-686 on Debian
Etch. (Tested with nmap from within the LAN.)
There may be a simple explanation that we're both missing.

COLS to read answers that aren't crossposted.)
