I want to use Orbot on my phone as a proxy server for my desktop or any computer on my local network. How/can I set Orbot up to let me do this?
Ok I figured it out. I need to bind the Orbot Socks5 proxy to my phone's internal IP on the local network.
Add this to the torrc from the debug settings in Orbot
SOCKSPort <localIP>:9050
You can try enabling the tethering mode, if your device is rooted. It should enable the SOCKS proxy to be bound to the 0.0.0.0 interface, which means other devices can see it on the network. If you know the IP address of your device, you can find the SOCKS proxy at port 9050.
