Tried this with a co-worker in the first days of smart working. It worked, but the only useful feature (in our context) was the file sharing, and it was confusing to setup and very slow to transfer.

Then I stumbled upon nebula (https://github.com/slackhq/nebula) and I stuck with it. It's by far the easiest way I found to setup an overlay network, and it checks all the marks:

- multi-platform (not tried on Android, but there are binaries for various arm devices, so maybe on termux...).

- P2P, with the option to use a fixed-ip device beacon as sort of DNS.

- works behind NAT if you use the beacon.

- very easy to setup and configure.

Now it's like we are working at the office again, with SVN, file sharing, chat, compilation servers, etc.

Definitely recommended.

I prefer ZeroTier, which is just as easy to set up and doesn't need a beacon to get through NAT. It was also developed by a small, independent outfit and not a bunch of Slack engineers.

Same here. I have been using ZeroTier as my primary road warrior VPN for two or three years now and it has been excellent. Has worked in many different hotels, cafes, etc as well as on airplane satellite internet. I have it on my OPNsense router at home and on my Android phone and Chromebook.

It looks really promising, worth to have a look. Thanks!
