Hi, I have a server on internal with outdated Apache version. Unfortunately it doesn't seem that I can update it without consequences for the server itself. Can I at list use Firebox to hide Apache version from outside world?
Perhaps this can help:https://www.tecmint.com/hide-apache-web-server-version-information/
From the Watchguard make sure you are publishing using Proxy Rule.
For HTTPS you must ensure that content inspection is enabled.
Under HTTP Response -> Header Fields, create the headers you want to remove.
Pattern Match: Server:*
Pattern Match: X-Powered-By:*
This is useful for applications that don't allow you to remove headers natively through the application or web config.
