How can I make a secondary WAN as default WAN?

 SonicWall has the ability to add more than one WAN connection on the firewall. This feature allows network administrators to choose a WAN port as the default WAN for making outbound (Internet bound) connections.

 For this article, we assume the following

• X1 is the Primary WAN connection and has been configured on the firewall.
• X2 Is the Secondary WAN connection and has been configured on the firewall.
• The WAN connections are part of Failover & LB Group.
