Bigleaf’s failover/replacement routers provide increased redundancy for your Bigleaf deployment. If your primary Bigleaf router fails, your failover router is standing by to keep you connected.
Placement of the failover router on your network should be done with your network security best practices and regulatory guidelines. However, the router must be able to connect to Bigleaf's network infrastructure over the internet to provide router management and monitoring. For example, it must be online to receive configuration and firmware updates so that if your primary router fails and you need to connect the failover router, it’s updated and ready to go.
Using an Ethernet cable, connect the WAN4 port on your failover router to any Internet connection that provides a DHCP IP address. Typically, a connection on your network behind the primary Bigleaf router provides the easiest and most reliable connectivity.
Port and protocol usage
Allow outbound connections on these ports and protocols for the IP address provided by the DHCP server to the failover router on the WAN4 interface.
