Use Tailscale Android as Subnet Router so devices can access another Site (site to site setup) #17618
Description
Tailscale 1.80+ on Android (TV) has a "Subnet Routing" section where you can "Use Tailscale Subnets" and Advertise your local subnet e.g. 192.168.1.0/24 to Tailscale.
But this is not a "Subnet Router", is it? I've set a PC to route the traffic aimed at a second site, via the IP of the Android TV, but it doesn't work. The Android TV itself -can- access the second site, but I can't get any other device on my LAN to do it via the Android TV.
NOTE: The same setup exists on my 2nd site, where everything works. The only difference there is that Tailscale is running on a linux laptop instead of an Android TV.
Are we limited by something in Android? I could "solve" my problem by installing Apache in Termux on the Android TV and doing a reverse proxy but that's too limited for my needs.
