Okay, so your router-box-thing *always* forwards 113 to the Debian box,
and the Debian box is then intelligent enough to know to which of your
other home machines to send the request? Which depends on it having seen
the outgoing request that triggered the remote end's IDENT request.
I know that masquerading/NAT with 'ipchains' supports *some* sort of
'related' traffic (like control and data ports on FTP connections), but
I am pretty sure that it would not spot that the incoming IDENT request
is related to the previous outgoing IRC client connection request.
But ... there is a program 'mident' for providing IDENT support on
networks with masquerading, for doing something like this. Check
http://packages.debian.org/cgi-bin/search_packages.pl?keywords=mident&searchon=names&subword=1&version=all&release=all
Perhaps that will help you.
