Using Serveo you may briefly expose your site to the Internet with end-to-end encryption, no sign-up required. Use this alongside Air Gapping to quietly poke a hole through your NAT or firewall to move information more discretely.
Serve and expose your site with the following command:
$ hugo serve --disableLiveReload & ssh -R 80:localhost:1313 serveo.net
Once started press
g for traffic inspection, or quit to go offline and use
fg to return to
hugo. Install dropbear or openssh if you need
