Welcome to the world of libnice :)
Yes, doing NAT traversal is far from being easy, the only solution is pretty
much to use the ICE specification and that's not easy to implement, so that's
why you'd need to use libnice.

For an example, you can have a look at the unit tests, like
tests/test-fullmode.c for example, although that does a lot of stuff. You can
see a quick example  in the documentation for NiceAgent :

For smaller examples, you can look at the libnice mailing list archives, some
people posted their example code where they were having problems. For example, a
very simple example can be seen here :
But make sure to click on the "Next message" to read the whole thread because
that example had a bug that I explained how to fix in the following emails.
Same for this thread :

I hope that helps,
