Default Gateway is the only gateway that works

[buecker]

I'm going to try and do a better job explaining my issue.

I have a multi-WAN setup.  I also have a group gateway setup for failover.  I have devices connected to my LAN.  One of those devices is another router.

Here is my problem:  If I select any other gateway other than "default" in the firewall the other router stops working but the rest of my LAN devices works correctly.

I have tried many combinations of settings and am still stuck.  I have unchecked the "block private networks" on each of my WAN interfaces.

What am I missing?

Missing outbound NAT is my guess
