I successfully have two WANs setup leveraging a switch and vLANs, then created virtual WAN1 and WAN2 interfaces in Untangle with external as parent.
Next challenge is how can I get failover to work? They don't supply WAN Balancer to the Linksys Untangle firmware because it "needs larger disk space and memory". But seems bogus since my flash drive has 30GB free and Linksys comes with 512mb RAM of which plenty free.
Thoughts?
Ideally I would have WAN1 primary but if packet loss occurs, would fail over to WAN2. If WAN1 stabilizes, fail back to WAN1. Is that so much to ask?
