Smart, and not something someone would realize if they'd been too insulated from how things work.

Regarding planes/cafes/guest/etc. WiFi, I now usually put any "emergency remote plumbing access" on port 443 (though usually not HTTPS), to reduce the likelihood of some random non-SPI ruleset blocking us in an emergency.



I think that by 2050, 443 will be the only port used by applications that require a non local connection, because the chance that some participant in the network has blocked any other port is simply too high.


Future generations will ask - “why does every packet header have this 2 byte reserved field with a fixed value of 01BB?”


Or setup a web ssh client and actually run HTTPS over port 443.


You can also proxy 443 out with ssh.
