Test now verifies that NAT fields contain CORRECT data, not just non-zero:
- Verifies nat_ip equals 127.0.0.1 (0x7F000001) - expected for localhost test
- Verifies nat_port is in valid ephemeral port range (> 1024 and <= 65535)
- Fails test if values are incorrect (not just warning)
This ensures the server correctly returns the client's external address
in the INIT_RESPONSE handshake packet.
Test output:
[CLIENT] PASS: NAT address is set: 127.0.0.1:9012
[CLIENT] PASS: nat_changes_count=0, nat_hits_count=0
[CLIENT] PASS: NAT IP and port contain valid values (127.0.0.1:9012)
