nginx + squid

[QuAzI]

Is it possible to hide squid under 443 port to prevent regular knocking and probings? For example I want to show default fast static page for bots and keep my services hidden (squid, ssh, sstp/openconnect if possible, mtproto)

Isn't squid usually used for outgoing connections? I am not sure I understand what you are trying to achieve... (there is of course no difficulty in serving static Web page and hiding the other protocols)
