There are times when you only need to link to physical interfaces together to link them into one broadcast
domain the most used scenario is when your 48 connects the internal network and your ISP router.
This can happen in a transparent mode.
Virtual wire here.
If you configure a virtual wire pair you're actually linking those two ports as if they were connected
using a cable.
No traffic will be captured between those only two interfaces.
We usually do with using an external interface and an internal interface.
The steps to do it is to link those to court members and to configure a policy that will allow traffic
in both sides.
Let's do it.
All right so let's move over to our network interfaces and let's decide that only the traffic that is
coming from internal 8 interface from the network that is connected to internal 8 interface will flow
over to our when one interface and to the Internet.
We can also decide that only traffic that will flow from internal aid will move over to internal 9 so
we can link to different networks on our 40 gig.
So let's create a new virtual wire here.
Let's name it.
Internet access
all right.
So let's call it on the Internet.
And in terms of FA interface members will choose when one and internal eight.
Now if we enable wildcard on the policy that we will configure later on will apply also to the virtual
lines not only to the physical ports but we will disable it for right now because we don't have any
violence attached to those interfaces.
Okay once created you will head over to policy and objects IP before virtual wire per policy.
That's a new policy selection that was made after you have created your virtual wire pair create new
name your policy decide whether it will be only a one way that is from when 1 2 internal 8 or the other
way or two way direction.
Source anyone can use it.
Destination what ever destination is needed.
Service all.
And if you wish to apply any security profile you can do it.
