I have a Samba mount at home (behind NAT, accessible via wireguard VPN), which works very well when accessing my home files when traveling (I travel a lot for work).
The only detail missing from this solution is sharing individual files with friends. I could give them access to my VPN, but that gives them access to everything, not just one thing I want to share. Also not all my friends are that tech savvy to manage connecting to a VPN.
What would be really great is to have a link-generator that punches a hole in the NAT to give them access to specific files. Are there any self-hosted solutions for that?


I use Pingvin. You upload a file to it and it generates a link. Has expiration on the link.
You can allow anonymous uploads or not, give friends logins etc.
I have it locked down to just me with a login and I use it to let others download the files.
I tried it but Copyparty worked better, it has a massive community suddenly and tons of cool features that mostly stay out of the way unless you enable them
Last I checked it was abandoned and no one is maintaining a fork either.
Good to know, thanks.
