Make MX67 NOT split traffic over 2 WAN connections

[jstam]

We have 1 MX67 that has 2 WAN connections configured, each on a different ISP, which is splitting the traffic over both WANs without having traffic shaping or load balancing enabled. The goal is to have all network traffic go over WAN1 except for VoIP traffic, which we have configured to go over WAN2 via flow preference for the VLAN with the VoIP devices. Packet capture after the configuration was complete showed traffic from the VoIP VLAN on both WANs and phone calls have no audio until the WAN2 is removed from the equation. Has anyone experienced anything like this before? Any help would be greatly appreciated.

Are you perhaps able to share the configuration as shown in Uplink Selection and SD-WAN policies, found under Security & SD-WAN -> SD-WAN & Traffic Shaping?

[jstam]

Here is the configuration for Uplink Selection and SD-WAN policies. The flow preference rule is not enabled currently, as it was causing the phone calls to not work, so we left it on the WAN 1 for now.

Looks fine. Maybe  you can do a reboot of the device after configuration to force the config and reset all current sessions. (Before of after working hours)

Unfortunately I did a reboot and that did not help. Also rebooted both modems for the two ISPs connected to each WAN and that did not help either.

Do you have two 450Mb lines, Meraki's WAN routing relies on the correct bandwidth being set and the use WAN2 is a preference, not a rule.  Please set those and see if it makes a difference

[jstam]

So change the Uplink configuration for each WAN to around the speed for each ISP?

[cmr]

Yes, you can set upload and download there and I always set it to be as accurate as possible.

[jstam]

ok thanks, I will try that and report back my results after.

It seems probable that either the primary WAN circuit or the Internet flow preferences are wrong.
