Maximum VPN tunnel interfaces supported per SonicWall UTM Appliance

With latest SonicOS , the routing protocol can use a numbered tunnel interface to establish a routing session. Numbered tunnels require an interface in the VPN zone using an IP address from a private subnet. This numbered tunnel interface can be used for the routing protocol session. After a numbered tunnel interface is added to the interface list, a static route policy can use it as the interface in a configuration for a static route based VPN. Routing protocols (OSPF, RIP, and BGP) can use it for dynamic route based VPN.
