Greetings, i am currently using the configuration below to provide failover between two DSL connections, all is working fine but i had expected outbound connections to be load balanced between the two DSL links on a round robin basis, however looking at the nat translations shows that only one of the links is being used, failover on the other hand works without issue.
track 1 ip sla 1 reachability
