@maxidev Use at your own risk, but here's how you do it for ssh via tor... this might get overwritten during an update, not sure. Also requires restarting the tor container so bitcoin etc. might get disconnected temporarily.
```
1. SSH in from Local network

  $ ssh [email protected]

2. Add config to tor

  $ nano ~/umbrel/tor/torrc

  ### Then add these three lines somewhere

  # SSH tor access
  HiddenServiceDir /var/lib/tor/ssh/
  HiddenServicePort 22 172.17.0.1:22

  ###

3. Restart tor service

  $ cd ~/umbrel/
  $ docker-compose restart tor

4. Grab hidden service URL

  $ cat ~/umbrel/tor/data/ssh/hostname

5. Exit ssh, and try ssh in again with tor

  $ torify ssh [email protected]
```
