After thorough tests last night I can confirm that also ftp works
perfectly under 2.1.24.
I got it working with the following setup:

ipfwadm -F -p accept <-------- with 'deny' it DOESN'T work
ipfwadm -F -a m -D

echo 1 > /proc/sys/net/ipv4/ip_forwarding

(with the default 2 it doesn't go)

I feel a bit uneasy about the default policy (the howto clearly states
that it may open a rather worrying security hole).
Any experience on the subject ?

Ciao, Paolo
