Eskimo007 Gonna go check out what WireGuard is/does, had never heard of it.
It’s kind of the replacement or upgrade over OpenVPN, I’m sure some people still use OpenVPN. If you were to do the RasPi VPN install you get a choice between Wire Guard and OpenVPN, at least that’s how it was when I did the Pi setup.
OpenVPN served me well for remote access but after WireGuard because more popular I switched. There’s two more built on the WG platform, Tailscale and Headscale. The advantage of Tailscale is that it works with CGN or Carrier-Grade NAT, there is also a pfsense package for Tailscale it but I have a pubic IP so WG works for me.
