I don't see anything obviously wrong, but I'm not an iptables expert.  One
thing you could try would be to testing the connectivity between net 1, net 2,
and the router as you make one change at a time.  That is, boot the box,
install the modules, check connectivity.  Then do the first iptables command
and recheck connectivity.  And so on.  That might help.

Perhaps it would help to change the default policy from DROP to REJECT?

There's also some way to get iptables to log rejected packets, I think.

As always, the doc may help.
