Re: Fortigate failover internet over 2 PPPOE connection
You find the priority setting in Static route>Advanced. "priority" in FortiOS means "cost" so higher priority would denote the backup route. If you set the priority equal then traffic would use wan1 or wan2 alternatingly (load balance).
If you put wan1 and wan2 into a zone (Network>Interface>New) then you'd have 2 advantages:
1- only one set of policies instead of two
2- in case of failover, the session does not need to be re-established as the zone interface has not changed, only one of it's members
But, to be honest, I haven't tested if a zone can be used with PPPoE.
BTW, you would benefit from an update to v5.4.9 - generally, not for this particular problem.
