Cant Save Changes to HTTP Client Standard Proxy Body Content Types
So all of my clients are receiving errors with windows updates specific to the HTTP Client Proxy - Body Content Type. I'm unable to save any changes I make here (it is unlocked). How do I disable this rule to allow the Windows EXE/DLL body content type, as the documentation below doesn't work (can't save any changes)? Again I've attempted this on 2 Watchguard T80 Firewalls and one M270. Is this because it's a predefined rule? If so what is the solution? Why allow changes to take place at all in here if you are not going to allow a save?
