I \"only\" needed to:</p>\n<ul>\n<li>\n<p>Setup a <a href=\"https://protonvpn.com/support/wireguard-linux\">Wireguard VPN connection</a></p>\n</li>\n<li>\n<p><a href=\"https://protonvpn.com/support/port-forwarding-manual-setup/#wireguard\">Forwarding a port</a> of the VPN server to my local HTTP server</p>\n</li>\n<li>\n<p>And dynamically update my <a href=\"https://www.noip.com/support/knowledgebase/installing-the-linux-dynamic-update-client\">NO-IP DNS</a></p>\n<p>NOW, I need to work on doing all that automatically at computer start, and keep it all up-to-date while it runs. Today I cheated and did things manually, but I am very close now! ;)</p>\n</li>\n</ul>\n",
