UNET LLAPI. Is NAT Traversal / UDP hole punching supported?

I tried the new network low level library today but failed to connect to my router. I assume it is because of the NAT/Firewall. Does the new library support UDP hole punching or any nat traversal mechanism? I could find any.

UNET does not (at least at the moment) support any kind of NAT traversal natively. It can however still be done with the help of RakNet and Open.NAT.

Here is an example implementation:

You’ll need an externally hosted server to run RakNet’s NATCompleteServer to act as the Facilitator between clients so they can punch through.
