Hello and welcome to this lecture.
It is now time to verify our configuration both from the test P.C. or user bases or land user up to
the free firewall.
And again going upstream from the free a firewall to the Internet.
So let's start now with the firewall.
So it's 48 1.
We'll have to log in.
So admin no password by default.
Just click enter and let's see if it has connectivity to the Internet.
Again we will do a verification of our routing.
So interfaces first show system
interface tab to autocomplete question mark.
And we see that we have this IP address on port one which is facing upstream to the Internet.
If we want to execute a ping we will not do just pink like in other vendors.
We'll have to say execute Bing and we will bring the Google DNS and connection is successful.
So at this point we know that.
So at this point we know that from the forget firewall we do have connectivity up to the Internet.
It is time also to verify connecting from the land P.C. going to the 48 firewall.
So I will minimize this window.
And again if I try to ping I will see that firewall is not responding.
Well let me let me just say that a firewall is totally different from a router and what I mean by this
is that when you first power up a router it will be completely open.
So nothing block by default.
But on the firewall side it's again different.
And it's because it's totally blocked and you will need to open any IP connectivity any ports any applications
to pass through the firewall.
So at this point I will just show you that indeed communication is working but ICMP hasn't been enabled
yet so hasn't been enabled on the firewall.
If I do a show system interface and port to and click enter it will now show me the configuration of
port too.
So I have the IP and I have some other some other configuration applied.
I will need basically just to allow ICMP connectivity to work on this port.
So let's do that.
So config sys interface enter.
Now you say edit port 2 and we'll say set.
Allow access.
And if you do a question mark now it will provide you the available options.
The first one it's ping.
So let's do it.
Set.
Allow access ping enter.
And again for exiting this configuration menu and applying the configuration you say and and enter.
Let's verify our work.
So show system interface and again port two.
Now it says set allow access ping.
Let's do that again.
So ping now the ping is successful and the basically if we go back to the diagram at this point we have
verified that connectivity is successful between the land B.C. going up to the firewall and at the same
time from the firewall going up to Internet gateway.
Do we have connectivity from the windows P.C. to the Internet.
Ping 8 8 8 8 8 8 8 we do not.
And this is happening because no network others translation has been configured yet on the firewall.
So that will be all for this lecture.
Thank you and see you in the next one.
