Hi @Dustin_Moore The best bet to control how outbound traffic is sent out different WAN and SpeedFusion connections is to use outbound policy. There you can dictate traffic flow pretty granularly. For instance, you could allow a particular PC to fail over to your hotspot on WAN 1, but not allow other LAN clients to use the WAN by excluding it from other outbound policies.
Here’s a great explanation of the different outbound policies and some example use cases. https://forum.peplink.com/t/understanding-and-configuring-outbound-policy
It’s worth noting that When there is more than one outbound policy they are implemented starting at the top of the list. The first rule that fits the traffic will be the rule that is followed, so you’ll want your ‘fine tuning’ rules near the top and your broader rules toward the bottom.
