Address or IP Address. You can also enter a range of IP Addresses if you wish this policy to affect a group of PCs. After

Days/Times. When will this policy be in effect? On every day? At certain times? Select if you wish to Allow or Deny

hours in which the policy will be in effect.

the pull-down menu and enter a range of ports in the fields beside it. If the service is not listed, you can add or even edit
a service by clicking the Add/Edit Service button.
