Adding a new firewall rule

You can create new firewall rules using either of the following methods:

Blank rule

A blank rule allows all traffic.

See “To add a new blank firewall rule”.

Add Firewall Rule wizard

If you add rules with the Add Firewall Rule wizard, ensure that you configure the rule. The wizard does not configure new rules with multiple criteria.

See “To add a new firewall rule using a wizard.

You should specify both the inbound and the outbound traffic in the rule whenever possible. You do not need to create inbound rules for traffic such as HTTP. The Symantec Endpoint Protection client uses stateful inspection for TCP traffic. Therefore, it does not need a rule to filter the return traffic that the clients initiate.

When you create a new firewall rule, it is automatically enabled. You can disable a firewall rule if you need to allow specific access to a computer or application. The rule is disabled for all inherited policies.

The rule is also disabled for the all locations if it is a shared policy, and only one location if it is a location-specific policy.

Note:

Rules must be enabled for the firewall to process them.
