Bigleaf’s warm spare routers provide increased redundancy for your Bigleaf deployment. If your primary Bigleaf router fails, your warm spare is standing by to keep you connected. For sites that use the warm spare availability option, certain protocols and ports must be permitted outbound onto the internet from the warm spare router.
Placement of the warm spare router on your network should be done with your network security best practices and regulatory guidelines. However, the warm spare 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 warm spare router, it’s updated and ready to go.
Using an Ethernet cable, connect the WAN4 port on your warm spare 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 warm spare router on the WAN4 interface.
