About firewall rules
Firewall rules are the policy components that control how the firewall protects
computers from malicious incoming traffic and applications. The firewall checks
all incoming packets and outgoing packets against the rules that you enable. It
allows or blocks the packets based on the conditions that you specify in the firewall
rule.
You can enable and disable firewall rules. The firewall does not inspect disabled
rules.
Symantec Endpoint Protection Small Business Edition installs with a default
firewall policy that contains default rules. When you create a new firewall policy,
Symantec Endpoint Protection Small Business Edition provides default firewall
rules. You can modify any of the default rules or create new firewall rules.
You must have at least one rule in a policy. But you can have as many rules as you
need. You can enable or disable rules as needed. For example, you might want to
disable a rule to perform troubleshooting and enable it when you are done.
Table 15-4 describes what you need to know about firewall rules.
