For identd to work with NAT:

a) Enable identd from the net to the firewall:

	ACCEPT	net	fw	tcp	113

b) Enable identd from the firewall to the local network:

	ACCEPT	fw	loc	tcp	113

c) On the firewall, you need to run an identd that will proxy AUTH
requests, based on the contents of the connection tracking table (I
assume that there are Netfilter-based daemons of this type -- I used to
run one under ipchains).
