Advice: accessing home network beyond home (lemmy.world)

Hi folks, I'm just getting into this hobby thanks to the posts in this community. So far, I've installed Ubuntu server 22.04 on an old laptop and got paperless working, and I'm pretty pumped. Now I would like to access it outside of my home network on my phone.

I have a Netgear R7000 with Advanced Tomato installed. Here's my plan, but I don't know if it would work... So I'm hoping for a peer review of sorts.

Get openVPN working on the router as a server.
make a certificate for my phone and use it as a client.
use my fedora laptop as the CA (?).

I think I need to use easy-RDA to make the keys and certificates...

Does that sound about right? It's this a good approach or is there something better/easier/more effective?

If there's a great tutorial around for accessing the home network externally, I'd super appreciate it. Would obviously prefer to do it myself and not pay for a service... I've been enjoying the learning experience!

Thank you for the write up! Very helpful.

The use case I was wondering about is batch printing from a cloud solution. The print batch files could be encrypted, but I work with multiple solutions and I’m not confident that all of them encrypt those files. If it’s possible to crack old batches, that could expose sensitive information.

If you send these files over SSH, you're good as that's encrypted by ZeroTier and then encrypted again inside the SSH connection (and SSH does have perfect forward security).

See their cryptography section of their docs for more info.

You can read more here about what they're working on:

It's been to long since I've read that to give anything more than a condensed "they're improving their crypto significantly with ZeroTier 2" (not to mention memory safety via Rust).
