You can use SNMP to monitor the wan interface on almost all routers,

and the router, the router would update the firewall via the routing
protocal if the line was down and use a higher admin distance on the

Keep in mind also that redundancy is fine for outgoing traffic, but to
actually route incoming traffic you must also have an upstream ISP(s) that
can handle redundant links, or you will have to obtain your own ASN and
manage your own BGP.
