My use case is the following:
* LAN Ports 1 and 2 route traffic through modem 1
* LAN Ports 3 and 4 route traffic through modem 2
* If modem 1 has no SIM or no connectivity, then the devices connected to LAN ports 1 and 2 will lose connectivity also.
* If modem 2 has no SIM or no connectivity, then the devices connected to LAN ports 3 and 4 will lose connectivity also.
I followed this very useful guide here: https://community.teltonika-networks.com/24221/dual-rutx12-routing-different-devices-internet-different
and everything works fine except:
[!] If modem 1/2 doesn't work, then it will simply route the traffic through the other modem that works, which is not what I want, so for example, device connected to LAN1 while Modem1 is dead, will simply access the internet through Modem2 :(
How can I make the devices on Lan1/2 and Lan3/4 simply drop connection if their corresponding modem is not working and not fail over to the other modem?
