Dragino setup for LoRa Server


Hello everybody,
I’ve just purchased Dragino LG308 and LG01 LoRaWAN gateways to do some tests.
I’m able to configure them as LoRaWAN forwarders to TheThingsNetwork,
but I want to use them with LoRa Server and LoRa App Server as I did using Laird RG186 Sentrius Gateway.

Question 1: do I have to install LoRa Gateway Bridge on my Linux machine where I’ve installed LoRa Server and LoRa App Server or I don’t need to install it (as for Laird RG186 Sentrius where LoRa Gateway Bridge is preinstalled)?

Question 2: how should I fill this fields?
