clojure friendly java library for traversing NAT

Question

I need to be able to establish a connection between two boxes that are both behind NAT? I have a central system that both sides can find each other through. I'm working in Clojure.

If you are trying to do UDP, take a look at stun4j. Otherwise, I think you may need to roll your own code from scratch.

But it would help a lot if you provided more information about what you were trying to do.
