Just to check the obvious, have you checked your FORWARD chain in the
filter table to make sure you are not accidentally dropping it?

Yes. Take a look at the iptables trace target (there are a handful of
tutorials out there).
Also, I would also suggest dumping iptables with the -v option, it will
give you a match count of your rules. That way you can see if it is even
matching at all.
