I am trying to setup these routers to basically take voice traffic and have it use one of the two WAN connections as it's primary and all other traffic use the other connection. I would like it so that if either connection fails they also failover between each other. I can figure out how to split the traffic but can't seem to find a way to do the fail over as well... Is this possible with either of these routers?
Thank-you for this. So I would assume this would work as well if instead of protocol I used subnet based binding? With the voice vLAN it is all on a different subnet so I was thinking to use this vs. trying to figure out the Protocol Binding.
Your assumption is correct. When you go in to setup the protocol binding simply select all traffic, with the source from VLAN 1, and specify the WAN you would like it to use, and do the same thing for the other VLAN to the other WAN.
Your rule would look something like this:
Service should be all traffic, source IP would be a range covering one VLAN, destination would be 0.0.0.0 to 0.0.0.0 and then select the WAN you want to use.
Then just setup another rule doing the same thing for the second VLAN and pointing out the other WAN port.
That way VLAN 1 would always use WAN1, unless it failed, and VLAN 2 would always use WAN2, unless that failed. This allows you to utilize your links how you would like and still have failover.
Another thing to keep in mind with protocol binding is that most secure traffic (HTTPS, SSH, etc) usually needs to be bound to one WAN, however since you are setting up a binding for all traffic on the entire VLAN, that shouldn't be necessary for you.
