How to register and connect Advantech 6610

Sorry, I’m still blocked, I really, really, need to solve this problem.

I managed to connect this gateway to the internet but now I don’t know what it’s needed to “signal” ttn console to change its state, until now, is “not connected”.

I noticed a gateway activation procedure, but it doesn’t work (but I guess it’s useless for this specific gateway):

I guess that somewhere I should insert an IP address that send some packets to ttn server, I found IP address (52.168.76.203 that is router.eu.thethings.network), but this address does not respond to ping and if I insert that address in configuration page of the gateway nothing happens.

As you can see there is also, a local Network Server, with other settings, here (for example) I could set a “connector”, I think this server act as “intermediary”, i.e. decrypt packets from node and send to another server or application (just set 127.0.0.1 in the address line you seen in previous screen) I try to set there IP address but still appear not connected.

Does ttn server (52.168.76.203) require some authentication? Could it is a protocol problem (MQTT / HTTP)? Or “connected status” is triggered from first packet sent from node to gateway? I haven’t a node for now, I only want to see a connection flag in that screen (first screenshot).

Thank you for your patience.
