allow DCC through iptables nat box

Hey

I have the following setup:

LAN 192.168.1.0/24
Linux box with iptables

       eth0   192.168.1.1
       eth1   ext_ip

internet

I use the following to allow internal clients to access the internet. iptables -t nat -A POSTROUTING -o eth1 -s 192.168.1.0/24 -d 0/0 -j MASQUERADE

Which rules should i use to allow DCC to and from an internal Mirc client on ip 192.168.1.2

I hope you can help me! ;o)

Best regards Lars Nielsen

You can use Patch O Matic module

5.4 irc-conntrack-nat patch

This patch by Harald Welte <[email protected]> allows DCC to work though NAT and connection tracking. By default, this module will track IRC connection on port 6667. But you can change this for another port with the `ports=xx' argument.
