I purchased the RUTX11 to provide a 4G failover as backup in case my wired internet line fails.
I am using an existing Router (Google Nest WiFi) that is currently setup to manage DHCP for my LAN. I have connected from the Google Router to the WAN port of the RUTX11. The Google Router has assigned it an IP address.
I would like the devices connected to the RUTX11 to get their IP addresses from the DHCP server on the Google Router. By default - the RUTX11 is acting as a second DHCP server, causing double-NAT. I tried to setup DHCP Relay but this always failed. I have looked through the wiki extensively and have not found a solution.
Can you please advice on how this should be configured?
