Zerotier on Unifi gateway

I’m running Unifi on a UDM-SE (dream machine SE). My cable modem based ISP has me behind a CGNAT configuration so I have no options for incoming traffic. Of course I can use Zerotier on any device inside my private network that I want, but that does not help me with various IOT devices that can’t install the network.

It looks like I could run the Zero Tier client on the UDM, but would it be possible to route traffic from any particular VLAN in my private network to the Zero Tier adapter to allow the IOT devices on that VLAN to be available on the zero tier network? Could I also route traffic from other VLANS to that network?

If so, what setup would be required to pull that off?

There is not any official support for Zerotier on UniFi but I think it can be done, but it’s not something that I have tested.
