DCC problems with BitchX

[aluminumsulfate at earthlink.net]

Greetings,

Do any of you have experience with getting DCC (direct client connect)
under IRC to work?

I'm using BitchX 1.1 (20040326) behind NAT firewall.  I've forwarded a
range of TCP/UDP (both) ports to my machine, and set the variables in
BitchX accordingly (DCC_USE_GATEWAY_ADDR ON, DCC_FORCE_PORT 8450,
NAT_ADDRESS to my public IP).

When making DCC/CDCC/XDCC queries, I don't seem to get any response...
(I went into a couple of warez channels just to give it a try and got
banned! :)

I can do direct chat and transfer files on the same machine (an ircd
at localhost:6667) just fine.  But not with anyone on the 'Net... :(
Sniffing doesn't show any traffic on the port which I specified.  Only
one of the intervening routers is running Sveasoft.

(Oh sweet! I just found my router has an ip_conntrack_sip. I'll have
to try that out...)

I seriously doubt that comcast is ip_conntrack_irc'ing my traffic just
in order to filter out DCC....  Any ideas?
