IRC connection tracking problem

[Bob]

Hi there,

I'm having trouble with IRC connection tracking.  I have both irc modules loaded.  I am connecting from a workstation behind the firewall.

Gateway LAN ip = 192.168.0.1
Gateway Ext ip = xxx.xxx.125.229
Workstation ip = 192.168.0.2
IRC server ip  = xxx.xxx.0.91

I am able to connect to connect to the IRC server and accept inbound DCC connections, but DCC send attempts fail with this message in the 
log:

Forged DCC command from 192.168.0.2: xxx.xxx.125.229:1698

/proc/net/ip_conntrack gives:

tcp      6 431991 ESTABLISHED src=192.168.0.2 dst=xxx.xxx.0.91 sport=47816 dport=6667 src=xxx.xxx.0.91 dst=xxx.xxx.125.229 sport=6667 
dport=47816 [ASSURED] use=1 

What am I doing wrong here?
