Hi
for this GW, just install chirpstack gateway bridge on the same server that you installed the chirpstack network server.
Then in your global_conf.json file you change the following.
"server_address": "ip fo the chirpstack gateway bridge server",
"serv_port_up": 1700,
"serv_port_down": 1700,
Just make sure you link the chirpstack gateway bridge to the same mqtt server as the network server.
And add the Gateway ID into the Application server.
