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.
