Ubiquiti USG Pro 4 - Two LANs - Firewalla Gold Doesn't See LAN2

I have a Ubiquiti USG Pro 4 which has built-in options for two LANs.  Two separate Ethernet ports come out of the USG.  Both LANs can see each other and both can access the Internet.  However, when setting up port forwarding on the Firewalla Gold, it sees LAN1 devices but doesn't see LAN2 devices.  The USG, of course, sees both LANs.

How do we address this issue, as port forwarding must be done for devices on both LANs?

Thank you.

  How are you connecting your network? how firewalla see the devices, depends on so many things; (such as, who is connecting to who? how is each device configured? (router or bridge?)

  Our configuration is Simple Mode.  All network devices other than the FWG are connected to LAN1 or LAN2.

  If you want to keep the USG running, I'd suggest using firewalla in bridge mode. It is far more simpler and easier to manage than simple mode.

  I'm not sure if that is possible with a Ubiquiti Pro 4.  As I recall, I tried that initially and in doing, so I lost all the features of the Pro 4 as it could not control or see anything downstream of the FWG.  That is not an acceptable situation for me.  If that is not the case, then I would be happy to hear what I missed in the first attempt.  We have an extensive network (almost 200 devices) at three locations, all linked via VPN and/or ZeroTier.  I really don't want to have to rebuild our whole setup.  :-)
