LAN device route traffic through Tailscale Flint 1

I have Tailscale running on my GL Flint 1 successfully. I also have Tailscale on a cloud server.

On my LAN, I have a device that needs to talk to MQTT on the cloud server. I cannot install Tailscale on this device.

Is there some way that I can configure requests from that LAN device to the cloud server:port, so they go over the TailScale tunnel rather than going over the open internet?

I thought about port forwarding, but that only seems to work on incoming WAN -> LAN traffic.

I answered my own question. I thought Tailscale subnet routers were one directional, but they are not. A LAN client can use the Tailscale IP to talk to any tailscale node. So if I configure my LAN device to write to MQTT on the tailscale address, it just works. Tailscale is incredibly useful, and easy to configure!
