Flow Preferences Not Working

I have our MX set up to send all Guest Traffic (10.0.0.0/8) configured to travel over WAN1. This worked until recently. Nothing has changed. Now all the Guest Traffic travels over WAN2. Has anyone else experienced this behavior?

Why are you using 10.0.0.0/8 as a selection criterium?
Could it possibly be that you are using NAT mode in your guest WiFi?  Do remember in that case your traffic is being source NAT'ed to the IP of the AP which possibly puts your traffic back with the rest of your network?

How are you testing it?

 

ICMP traffic is not subject to traffic shaping rules. As a result, Flow Preference will have no impact on ICMP traffic.

You're probably running version 17.10.2, have you tested it with another version? I think you have to open a support case.

We are on 17.10.2. No, I have not tried another version. I do have an open support case at the moment. Waiting to hear back from the support engineer. Thank you.
