00:00:08,030 --> 00:00:14,760
Before we continue into interfaces and later on policies we need to understand one key concept.

2
00:00:14,840 --> 00:00:18,110
Traffic flows in two directions.

3
00:00:18,110 --> 00:00:27,570
Whenever a traffic is destined to our 48 that is it is destined towards an ingress interface.

4
00:00:27,770 --> 00:00:31,090
Whenever a traffic is leaving our 40 gate.

5
00:00:31,340 --> 00:00:37,250
Then it is destined towards an egress interface.

6
00:00:37,250 --> 00:00:48,860
So if we have for example a marketing lan that is connected to our 48 through Port one interface and

7
00:00:48,860 --> 00:00:58,940
is destined to the Internet through when one interface then our port one is the ingress interface and

8
00:00:58,940 --> 00:01:02,810
our when one is the egress interface.
