The Gateway needs a dedicated IP address on the same VLAN as the Modbus automate. It can be set up as DHCP or static IP.
The default configuration is static IP:

• address: 192.168.1.100

• netmask: 255.255.255.0

• gateway: 192.168.1.1

The Gateway should be synchronized to a NTP server in order to have valid timestamps of the Lora payload.
The default NTP servers configured are 0.pool.ntp.org and 1.pool.ntp.org, however this won't be valid if the Gateway doesn't have internet access.
