  • On pfSense WAN you just need to setup an OpenVPN Remote Access server (probably want (SSL/TLS + User Auth)) with local port 44444.
    Add a firewall rule on WAN to pass any traffic to port 44444 - you can limit the source IP addresses if you have any idea what public IP address/es the incoming connects wil come from.
    If the public IP that is forwarded in to pfSense WAN is dynamic then you need to use a dynamic DNS provider and set that up also in pfSense so that it keeps a public name pointing at your current public IP address.
    Then install OpenVPN client on the remote PC…
