Firewall Settings

The flow of incoming and outgoing traffic is controlled by the configuration setting you make. These decisions are made in accordance with a sound security policy that defines the kinds of risks that are acceptable to you or your firm.

WatchGuard identifies several commonly used services that are used to define incoming and outgoing access. A service is the combination of protocol and port numbers associated with a specific application or communication type.
