Firewall Rules
The Firewall Rules screen allows you to define "Firewall Rules" which can allow or prevent
certain traffic. "Traffic" means incoming connection attempts, not packets.
By default:
• All Outgoing traffic is permitted.
• All Incoming traffic is denied.
Because of this default behavior, any Outgoing rules will generally Block traffic, and Incom-
ing rules will generally Allow traffic.
