Configuring Outgoing Services

You control traffic that starts in the trusted or optional network and
goes to the external network using outgoing services. Usually, the
Internet is the external network.
By default, the Firebox® X Edge allows all traffic that starts in the
trusted or optional networks to go to the external network. To deny
outgoing connections, you must make rules for those connections.
