Port forwarding for TK102-2

Hi.
I have ch TK102-2 and set up in settings ip:port of webpage of my traccar server. This server is deployed behind gateway. So i forward this port to external. And i don't see this device on the map.

In this case i need to forward 5001...or other ports?

Each device protocol has its own port:

https://www.traccar.org/devices/

so i can set up any port number of server in gps. But i need to forward port that in use by protocol?

You can use any external port you want. Just make sure it's forwarded to correct Traccar port.

Question was in forwarding 5023 port
