Multi-Wan as a backup connection not failover/load balancing
-
I tried searching for this but came up empty.
Here is the scenario. I have a remote site (home) that is three hours away and from time to time the modem needs to be rebooted after the internet hiccups. So the internet is down for days before I can get to it and bounce the modem.
So as a solution I put a LTE modem in the router. Since I am paying by the GB I don't want a failover scenario to burn all my data and end up with a huge surprise bill. I just want to VPN into the LTE connection and reboot the cable modem via its webpage. (The ISP reboot signal is ignored by the modem for some reason.) The LTE connection is only there for "emergency" access and only via VPN. All the guides I find are for failover/load balancing, etc which I don't want to do in this scenario.
Can somebody help me out with configuring the second WAN as a backup connection to the primary WAN? I have OpenVPN and IPSec tunnels between sites on the primary WAN.

The LTE connection can only be used for outbound traffic if there is any route defined to go over it. So if there is no route, no traffic.
If you only want to use it for a dial-in VPN, you don't need to set it as gateway. Simply connect the LTE modem to a pfSense interface and fire up an OpenVPN server listening on this interface.You will also need a dynamic DNS for the LTE, so you can connect to the hostname when you need.
