Now the Sonicwall is using the Secondary WAN to go through Sprint Cellular with a gateway of 18.104.22.168. Assumptions: Primary router is configured in a 192.168.1.X subnet and leases DHCP address in the same pool.
Choose a local IP in the same subnet that is not being used as your main router. If your main router is 192.168.1.1 then as long as it is not in use 192.168.1.2 will work.
