Firewall Rules
Firewall Rules examine the control information that describes an individual packet. They either block or
allow that packet based on rules that are defined on these pages. Firewall Rules are assigned directly to
Computers or to Security Profiles which are in turn assigned to a Computer or collection of Computers.

General Information
Name: The name of the Firewall Rule.
Description: A detailed description of the Firewall Rule.
Action: Your Firewall Rule can behave in four different ways. These are described here in order
of precedence:
1. The traffic can bypass the firewall completely. This is a special rule that can cause the
packets to bypass the firewall and DPI engine entirely. Use this setting for media
intensive protocols where filtering may not be desired. To find out more about the
bypass rule, see "Bypass Rule" in the Reference section.
2. It can log only. This means it will only make an entry in the logs and not interfere with
the traffic.
3. It can force allow defined traffic (it will allow traffic defined by this rule without
excluding any other traffic.)
4. It can deny traffic (it will deny traffic defined by this rule.)
5. It can allow traffic (it will exclusively allow traffic defined by this rule.)
Only one rule action is applied to any particular packet, and rules (of the same priority) are applied
in the order listed above.
