1
00:00:07,920 --> 00:00:20,220
There are times when you only need to link to physical interfaces together to link them into one broadcast

2
00:00:20,220 --> 00:00:31,820
domain the most used scenario is when your 48 connects the internal network and your ISP router.

3
00:00:31,830 --> 00:00:35,450
This can happen in a transparent mode.

4
00:00:35,490 --> 00:00:38,140
Virtual wire here.

5
00:00:38,370 --> 00:00:47,520
If you configure a virtual wire pair you're actually linking those two ports as if they were connected

6
00:00:47,520 --> 00:00:49,800
using a cable.

7
00:00:49,830 --> 00:00:57,020
No traffic will be captured between those only two interfaces.

8
00:00:57,090 --> 00:01:03,420
We usually do with using an external interface and an internal interface.

9
00:01:03,420 --> 00:01:13,020
The steps to do it is to link those to court members and to configure a policy that will allow traffic

10
00:01:13,270 --> 00:01:14,800
in both sides.

11
00:01:15,840 --> 00:01:18,430
Let's do it.

12
00:01:18,620 --> 00:01:26,960
All right so let's move over to our network interfaces and let's decide that only the traffic that is

13
00:01:26,960 --> 00:01:35,540
coming from internal 8 interface from the network that is connected to internal 8 interface will flow

14
00:01:35,540 --> 00:01:40,800
over to our when one interface and to the Internet.

15
00:01:40,880 --> 00:01:48,800
We can also decide that only traffic that will flow from internal aid will move over to internal 9 so

16
00:01:48,800 --> 00:01:54,100
we can link to different networks on our 40 gig.

17
00:01:54,590 --> 00:01:58,640
So let's create a new virtual wire here.

18
00:01:58,730 --> 00:02:00,620
Let's name it.

19
00:02:00,800 --> 00:02:02,990
Internet access

20
00:02:07,350 --> 00:02:08,110
all right.

21
00:02:08,130 --> 00:02:11,200
So let's call it on the Internet.

22
00:02:11,730 --> 00:02:19,470
And in terms of FA interface members will choose when one and internal eight.

23
00:02:19,560 --> 00:02:28,640
Now if we enable wildcard on the policy that we will configure later on will apply also to the virtual

24
00:02:28,640 --> 00:02:36,230
lines not only to the physical ports but we will disable it for right now because we don't have any

25
00:02:36,710 --> 00:02:40,190
violence attached to those interfaces.

26
00:02:40,500 --> 00:02:49,030
Okay once created you will head over to policy and objects IP before virtual wire per policy.

27
00:02:49,030 --> 00:02:59,020
That's a new policy selection that was made after you have created your virtual wire pair create new

28
00:03:00,650 --> 00:03:11,000
name your policy decide whether it will be only a one way that is from when 1 2 internal 8 or the other

29
00:03:11,000 --> 00:03:14,980
way or two way direction.

30
00:03:15,110 --> 00:03:19,230
Source anyone can use it.

31
00:03:19,390 --> 00:03:24,340
Destination what ever destination is needed.

32
00:03:24,490 --> 00:03:28,110
Service all.

33
00:03:28,280 --> 00:03:35,330
And if you wish to apply any security profile you can do it.
