You can use Patch O Matic module

5.4 irc-conntrack-nat patch

This patch by Harald Welte <laforge at gnumonks.org> 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.
