title: How to secure the web login of an equipment with public IP address
body: <p>We have equipment which have public IP addresses and we don't have SSH access to it. In order to secure their login screens, we need to use the HTTPS, but when we do that it is always complaining about insecure connection due to wrong SSL certificate. I am aware that we cannot issue SSL cert on an IP, but the other problem is that we don't have access to the equipment either in order to install a new SSL certificate. So what are the security recommendations in this case. Is the traffic still secure and encrypted in case of SSL mismatch. </p>
  
  <p>I know that we can limit the networks who have access to this IP, but are there any other security measures? </p>
