I have a Firewalla Red. I've setup a new network with new IP ranges and need to put the Firewalla on a different subnet. I've tried going into the Advanced > Network Settings and manually update the IP address, but I get an error message each time that says "Failed to Update Network settings".
Tried several times and keep getting same results. Also, tried SSHing to the box and manually changing the IP addresses via the instructions on this site, but that also fails since it won't let us save the "Interfaces" file after changes are made.
Will the Firewalla grab a DHCP address on the new subnet or will it just keep the old IP. At this point I'm stuck since nothing seems to work..
