How to configure numbered VPN tunnel

In SonicWall, a numbered tunnel refers to a VPN tunnel configuration where unique IP addresses are assigned to each endpoint (or interface) of the VPN connection. This setup allows each end of the tunnel to have a specific IP address, creating a numbered, point-to-point connection between two networks.

Advantages of Numbered Tunnel VPN

• Simplified Troubleshooting: Unique IPs for each endpoint make it easier to troubleshoot by tracking traffic and identifying issues.
• Enhanced Routing Control: Provides precise control over routing between networks.
• Compatibility with Routing Protocols: Works seamlessly with dynamic routing protocols like OSPF/BGP including static routing.
• Easier Management: Allows better management as a point-to-point connection.
