What does tcpdump show for port 22 traffic on eth1 when you try to ssh in?

There could be any number of problems.  Based on your description of the
setup, you shouldn't have to worry about iptables or forwarding through
the box.  If tcpdump just shows unexpected addresses, then NAT
(somewhere) is your problem.  If nothing (or only one direction) shows
in the tcpdump, then routing (or firewalling via iptables) is your problem.

Regards,
Mike
