Client Firewall Rules
Client Firewall applies the rule at the top of the firewall rules list.
1. Client Firewall applies the rule at the top of the firewall rules list. If the traffic meets this rule’s
conditions, Client Firewall allows or blocks the traffic. It doesn't try to apply any other rules in the
list.
2. If the traffic doesn't meet the first rule’s conditions, Client Firewall continues to the next rule in the
list until it finds a rule that the traffic matches.
3. If no rule matches, the firewall automatically blocks the traffic.
To modify Core Networking or Default Rules, expand either Core Networking Rules or Default Rules, select
the rule to modify, and edit the desired settings, and click OK. The settings are described in the table
below.
Alternatively, click one of the following buttons to perform the desired action:
Add Rule - Adds a firewall rule.
