Packet Filters
Packet filtering allows you to block users from accessing specific services (or applications) on the Internet. For example,
the administrator can deny the users access to SMTP/POP3 email services on the Internet, while allowing them access to
the Web/HTTP services. By default, packet filtering is disabled.
Select Packet Filters from under Security Settings in the left hand window.
