Nginx as reserse-proxy for SSH

You need create a stream and defined SSL

stream {

    map $ssl_server_name $target_backend {
        host01 192.168.10.223:22;
        host02 192.168.10.222:22;
        host03 192.168.10.112:22;
    }

    server {

        listen 8443 ssl;
        ssl_certificate /etc/letsencrypt/live/ssl/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/ssl/privkey.pem;
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;

        proxy_pass      $target_backend;

    }

}

Command example to run SSH connect will be look like below:

ssh -o "ProxyCommand=openssl s_client -quiet -servername %h -connect <IP_LOADBALACE>:8443" host01
