I'm considering using an EdgeRouter 8 as a load balancing/failover router for a setup with 3 (possibly 4 or 5) WAN connections. I'm not familiar with EdgeOS, but looking at the guide there are wizards included for dual WAN load balancing.
I presume it's possible to configure it to load balance with more than 2 WANs?
How complicated is it going to be to configure, presumably beyond the GUI and into CLI, is that reasonably easy to learn?
I don't think it will need anything special in terms of prioritising routes, literally just route each bit of traffic to the quietest WAN connection. All the WAN connections will have a similar bandwidth.
