SD-WAN with 2 WAN/External IP addresses
Hello, we have a WatchGuard m200 device in hosting center with a current ATT Fiber Internet circuit. The WAN/External IP is used for several site-to-site and client VPN connections so important that IP remains the same. We would like to add a secondary/backup Internet service from another provider like Comcast or possibly another connection from ATT, like their Cellular service. We can configure WAN fail-over to switch to the secondary/backup WAN connection, however we need to keep the Primary External IP as there are many site-to-site VPN connections that use the Primary IP. Does SD-WAN solve this problem where we can add a secondary/backup Internet service and configure policy to fail-over to secondary connection but still maintain the Primary WAN IP address on secondary connection?? As mentioned, need the External IP to be in place to not impact external connections. Please advise if SD-WAN configuration would solve this. Thank you.
