I have a similar issue in that I’m trying to split traffic across one of three links at any given time depending on the source/destination. This is currently setup in a lab environment with a B310 and B1350 running 7.0.1FW.
It seems from a status page, things are setup the way I need them to be, though the 2nd and 3rd tunnels are showing inactive, similar to the second link above.
For the purposes of this thread, I’ll be concentrating on route 3 of my configuration. The two images below show the configuration on both sides. Though it shows route 1, you can assume that route 3 has the appropriate config in that it has WAN3 as the priority, and the other WAN interfaces in their respective priority.
The next two are the policies in question. For the sake of brevity, I only show the one side. It’s identical with obvious differences (source network).
And the below shows the status on both sides.
Any traffic initiated from a host on either side of the link goes down route 1, which tells me the policy isn’t actually doing anything. I’ve not configured the full policy that will exist yet, as this is the initial test for this setup.
I’ll open a case if I need to, but wanted to get a more conclusive thread going on this issue.
