Firewall policies are automatically enabled when you create them. You can disable
a firewall policy as needed, and then enable it again. You must enable a firewall
policy for it to be active.
You might want to disable the firewall for any of the following reasons:
You install an application that might cause the firewall to block it.
A firewall rule or firewall setting blocks an application due to an administrator's
mistake.
The firewall causes network connectivity-related issues.
The firewall might slow down the client computer.
Description
Firewall rules are the policy components that control how the
firewall protects client computers from malicious incoming
traffic and applications. The firewall automatically checks all
incoming packets and outgoing packets against these rules. It
allows or blocks the packets based on the information that is
specified in rules. You can modify the default rules, create new
rules, or disable the default rules.
When you create a new Firewall policy, Symantec Endpoint
Protection Small Business Edition provides default firewall rules.
The default firewall rules are enabled by default.
See Setting up firewall rules"
You can specify the security level of the firewall rules. The
security level determines how stringently the firewall rules are
applied.
See Adjusting the firewall security level"
You can send users a notification that an application that they
want to access is blocked.
These settings are disabled by default.
