That worked, but performance is terrible, but it's only terrible in the
return direction. I confirmed that on the other end the quality is fine,
but on my end it's not even usable. Any ideas? I wonder why the return
is so awful.

Define 'performance is terrible'. That isn't a very useful description of the problem.

What do traceroute and ping look like from each end? Are you seeing lots of packet loss or RTTs or is something else entirely happening? What _other_ iptable rules are in your system? What does your route table look like? Are you seeing anything in /var/log/messages?

You haven't given anywhere near enough information to guess at causes.
