Currently my customer has Internet connection with ISP X at 1GB download and 30GB upload. They are going to purchase an additional incoming connection from same ISP to make the connection dual.
Also They will purchase another incoming connection from another ISP (Y) as a failover option.
So I'm looking for the best multi-WAN methods between them. Does anyone have any suggestion? Based on what I know I can only chose one method between all external connection, right? Is there any way to use Round-robin between X connections as a primary and then set failover with Connection Y?
The Firebox model is M270.
