I have a PRTG installation on a public IP address. It is configured HTTPs but we only access it from one office with a fixed IP address. We would like to restrict it so that if other Internet users go to our installation they do not see the PRTG logon page. For various reasons it is difficult for us to add this restriction using a firewall. If the PRTG website was running in IIS we could easily add a source IP restriction but I can't see a way to do that in the Paessler configuration? Is it possible ? If not can you add the feature ? I think it would improve security if the website was only visible to people with valid logons.
