We have compiled the client and server examples.

We have a server (A) with a public ip behind a restricted cone nat.
Our client (B) is behind a restricted cone as well.
We have the Punch Server Host set to the public ip of (A) and we even opened the firewall port to 6776

On our client when we run the compiled console app, we get asked:
[CONNECTOR] Enter the address of the listener you want to punch:

Which ip is this referencing?

Our goal is to simply create a punch / connection from B to A so that we can then proxy services from B to A as requested by A.
