Enabling or Disabling the OfficeScan Firewall
During the OfficeScan server installation, you are prompted to enable or disable the OfficeScan firewall.
If you enabled the firewall during installation and noticed an impact on performance, especially on server platforms (Windows Server 2003, Windows Server 2008, and Windows Server 2012), consider disabling the firewall.
If you disabled the firewall during installation but now want to enable it to protect the agent from intrusions, first read the guidelines and instructions in OfficeScan Agent Services.
You can enable or disable the firewall on all or select OfficeScan agent endpoints.
