Before we continue into interfaces and later on policies we need to understand one key concept.

00:14.840 --> 00:18.110
Traffic flows in two directions.

00:18.110 --> 00:27.570
Whenever a traffic is destined to our 48 that is it is destined towards an ingress interface.

00:27.770 --> 00:31.090
Whenever a traffic is leaving our 40 gate.

00:31.340 --> 00:37.250
Then it is destined towards an egress interface.

00:37.250 --> 00:48.860
So if we have for example a marketing lan that is connected to our 48 through Port one interface and

00:48.860 --> 00:58.940
is destined to the Internet through when one interface then our port one is the ingress interface and

00:58.940 --> 01:02.810
our when one is the egress interface.
