What happens with outgoing connections that have no policy on the Firebox?

When there is no specific policy set on the Firebox for outgoing connections, the default behavior is to block the traffic. This means that any outbound connection request that does not match an existing policy or rule will not be allowed to pass through the firewall.

Firewalls like the Firebox are designed to restrict traffic and enforce security protocols, so if an outgoing connection attempt does not have an associated rule permitting it, the firewall will actively block that traffic from being sent. This is an essential practice in network security, as it helps prevent unauthorized access and potential data leaks.

In contrast, sending traffic to the default gateway or dropping traffic would imply a different handling of the connection, either allowing it to be sent elsewhere or discarding it without a formal block action. By blocking, the firewall ensures that all connections are scrutinized according to its security policies, ensuring a more secure network environment.
