TCP Server Connection

Hi,
Copter is equipped with 4G modem.

Because it is behind Carrier NAT I only get a private IP.
That’s why I have to connect to MP via TCP, and MP has to be TCP server, copter client.

Is that possible?
If I enter localhost I get a connection error.

could you use udp instead? it would be much better given the environment. missionplanner support both client/server under udp.

Hello Jack: did you find the solution for your issue?. Thanks,
