======Private LAN VPN Access======
The scope here concerns use of VPN (Virtual Private Network) to gain secure access from the public network to a local private network.  It relates to private secure access and use from the public network.  It does not consider public VPNs setup for public use.

There have been considered 3 different levels of access as described by the applications used:
  * Nextcloud - a full privately hosted publicly accessible file shareing application, with many additional features
  * Privatebin - An encrypted file publicly accessible file sharing server
  * Syncthing - A files synchronising system
  * Wireguard - A VPN server

These applications and their scope are described further below.

=====Nextcloud=====
Nextcloud is an open source content collaboration platform.  At its core is file-sharing, but it has many other core functions as well as extensibility with additional installed applications.  While Nextcloud can securely share files it is not focused as a **simple**, public, and secure file-sharing platform.

I have been using Nextcloud and before that Owncloud from which Nextcloud was forked since circa 2013.  My server setup is described here:
  *kptree  [[https://wiki.kptree.net/doku.php?id=docker_notes:docker-nextcloud|nextcloud]] is Docker based setup, that I currently use, since 2022.
  *kptree [[https://wiki.kptree.net/doku.php?id=home_server:web_server_setup#nextcloud_setup|nextcloud]] is a VM setup previously I used.

=====Wireguard=====
I previously successfully setup [[https://wiki.kptree.net/doku.php?id=linux_router:wireguard|wireguard]] on my router.  This was installed on "bare metal" as was the nftable based router firewall. I later installed Bind9 DNS and Kea DHCP programs in Docker containers.  I always run Docker in a VM to prevent Docker's packet filtering from affecting the bare metal firewall rules.  I did not move Wireguard to a Docker container as I did not have the need at the time.
