Load sharing enables you to use both connections to the internet at the same time, but do not provide fail over support. When configuring for load sharing, you need to ensure routing is configured for both external ports, for example, WAN1 and WAN2, have static routes with the same distance and priority.

Further configuration can be done using Equal Cost Multiple Path (ECMP). For more information on ECMP and load sharing, see the Advanced Routing Guide.
