I will assume you have (not sure from your description).

[ host ] <----> [ router] <----> [ NAT ]???

I am afraid I have no idea why it want work. Can you provide more
details as to what you mean "it didn't work properly?" Also, how have
you configured your NAT (ipmasq)?

Tools I would use to debug such a problem:

tcpdump
netstat
ipchains -L -M          (for linux 2.2.x - run on NAT machine).

The major problem I have had in the most with ipmasq is that it wasn't
operating on expected packets, and just passing them straight through
(due to configuration problem).
