IRC DCC between 2 clients on the same net.

[difro@xxxxxxxxxxxxx (Jihoon Chung)]

I have 2 clients behind a masquerading gateway.

When one of them DCC SEND to the outside world, everything's fine.
(Thanks
to ip_conntrack_irc/ip_nat_irc)

But when I DCC-SEND from one client to the other client on the same
network, it doesn't work.  The sending side fails almost immediately.

Is this normal?
I'm using kernel 2.4.17.
