Port 1700 does not appear on Private Backend

TTN Network and Services v2 Backend
1

Hi,

I have deployed a private backend on localhost (not through Docker-Compose) following the Private Backend Guide and seems that I can initialize each component correctly.

However, how am I suposse to configure the Gateway (Kerlink GW) to use my private server using the 1700 port if this port number is not even in the listening status?

If I configure the gateway to point to the private backend (192.168.x.x) through 1700 UDP, a ICMP Port Unreachable error message appears.

Am I missing something? Other ports (1883, 1900, …) are shown correctly.

Thanks a lot in advance,

B.
