Hello and welcome to this lecture in this lecture we talk about the course lapped apology and goals.
So I have prepared this apology with three locations the headquarters and two branches and in the first
place we will be going.
And let me just grab a pen.
We will be configuring the HQ for the gate.
We will start with basic setup initialization.
So we will configure IP addressing both on the web interface and on the land interface.
We will also have a management interface here.
So we'll have a P.C. and we will be configuring basically the HQ for the gate through the web.
So the web user interface next will move to the branch for the gate and we will do the same.
We will configure IP addressing and also provide management access through the management port.
And again we will have a management station here.
Now after configuring this two and also configuring connectivity so IP connectivity between the two
sides.
And we will test these through and ICMP session.
So we will ping from branch 48 to H2 48 or the other way around.
It doesn't matter.
We will be configuring the IP VPN setup between the two sites and we will run.
In this case the IP saying VPN wizard.
But anyway you will see that in the upcoming lectures.
Now the end goal if the IP VPN will be successful is that we will have a VPN tunnel built between the
two sides.
And in the end the goal for any site to site VPN is that we can ping between the two pieces so that
they look just as if they were in the same.
So ICMP connectivity between the branch land P.C. and HQ land P.C. should be obtained but at the end
of this configuration.
Now next we will move to the branch where we no longer have a 48 firewall but we have a Cisco say.
So we will configure again here IP connectivity and IP addressing on on the interfaces as any firewall.
This Cisco I say also has a management interface and it's zero by zero but any way we will configure
access so that we are able to talk says the firewall through as the m..
So the graphical user interface of the Cisco NSA.
And when this is done we will then configure the tunnels the IP SEC tunnel between again the HQ 48 and
the Cisco RSA and again we will have to have ICMP connectivity between the land P.C. of the HQ and the
branch with Cisco as a firewall.
Now as network engineers we do know that sometimes things break or at least they don't work in the first
place.
So we have to be ready in order to troubleshoot.
So what to do in order to troubleshoot IP SEC VPN.
And for this reason I have prepared in the last section of this course a couple of troubleshooting scenarios
so that we are able to overcome these kind of situations.
So troubleshooting scenarios on the 48 firewalls are also included.
So thanks a lot.
And join me in the next lecture.
