It is important to note that the Routing Table option does not do load balancing on connections to the Internet. The XTM device reads its internal route table from top to bottom. Static and dynamic routes that specify a destination appear at the top of the route table and take precedence over default routes. (A default route is a route with destination 0.0.0.0/0.) If there is no specific dynamic or static entry in the route table for a destination, the traffic to that destination is routed among the external interfaces of the XTM device through the use of ECMP algorithms. This may or may not result in even distribution of packets among multiple external interfaces.
