I’m sure there’s a post about this already, but I don’t really know how to search for it to find the answer, so I apologize in advance for that.

I have some self hosted services in 2 separate houses that are 2 hours away from each other. I use tailscale to access them on my devices, but I’ve experienced some nuances with Tailscale that would be impossible to walk other members of the two households through trouble shooting.

I want to avoid port forwarding if I can.

There are docker services at house A at 192.168.86.5 that I would like the users of house B at 192.168.4.x to be able to access without extra software being added to each phone, TV, and computer.

Would anyone be able to point me in the right direction, either by search keywords or even links to how to do this?
