- Plesk for Windows
- Rules specified in Plesk Firewall are not applied on a server with public IP (they are ignored). For example, a port 8880 is setup to deny all traffic, but external connections on 8880 port are possible.
- In Windows Firewall > Monitoring there is the following warning:
CONFIG_TEXT: These settings are being managed by vendor application Norton Security.
Norton overwrites settings defined in Windows Firewall side.
Disable Norton Security software or configure it properly so that it does not interfere with settings defined in Windows Firewall (and in Plesk Firewall).
