If you set up resources correctly on his netbird network it effectively is a split tunnel. You don’t have to route anything through it but his “file shares and stuff”.

I have a rather gnarly nested double nat within my house where the homelab is isolated behind it’s own separate firewall and have some limited resources on both. It’s been perfectly serviceable.

I believe I have a resource of *.whathaveyou.net on the netbird gateway inside the network and no default route. If you do have that default route I believe you can have it as a separate resource and disable it.

Self-hosted netbird is pretty incredible to be honest.

Traditionally I open a README.md in the dir the application lives in after I configure something I will open my browser history, and dump every link I clicked into the file.

I then copy paste a choice selection of my shell history into the file.

This is the bare minimum. It’s easy to do, takes like 5 minutes, and you will be happy to have it in 8 months. I would make the argument that anyone who tells you to do anything else can suck it. Do the readme first, any “better” documentation second.

Getting Into the habit of doing this matters more than a good documentation system. You will be lazy and try to get around to documenting something later. Don’t let it be later. Shitty link dumps are still gold mines for your future self
