Hey everybody and welcome to the next module.
So in this module reading be going over the firewall P.F. sense now we're gonna be going over how to
install it how to work with it how to change configurations how to handle VPN and DMD firewall rules.
We're going to touch base on this quite a bit.
Now this is gonna be a hands on course.
I want you to build this and install it as we go through in each video but also understand that P.F.
sense is not a high level firewall so you're not going to find it in Fortune Five thousand companies
you're going to find it in the realm of like one hundred two maybe three hundred employees or people
using it at home.
It's a powerful firewall in that regard but it's not meant to be running gigs and gigs and gigs of traffic
through it all at the same time and keeping and supposedly maintaining that.
So you're going to find it that's much smaller companies now the link above brings us to this page with
this option selected.
Now what I want you to do is go into architecture do AMD's sixty four and then select C.D. image ISO
installer and then whatever Mir is closest to you go and hit download.
And that's going to install or bring down a dot.
GC So On windows you can use one RAR which is free if not go ahead and download it and that will open
up this on Linux and Mac users you can either double click on it or if you are on the command line use
guns.
Now once you have the ISO we're gonna go ahead and click on new for a new VM rename it P.F. sense and
we'll change this to Linux and other Linux 64 bit and we'll get some memory would just create create
perfect and then we'll click on settings go to storage give it a new hard disk or undo hard disk.
New optical drive choose disk and we will give it our P.F. sense ISO
perfect so and then make sure a network is set to not so we can reach on our machine.
OK then we'll go ahead and hit start now this will start going through the installing process and the
first prompt that comes up we're going to leave it as complete default don't press anything just let
it go through and then it'll start booting up the installer for us.
Now that we put it up and go ahead and hit space or enter or enter for to accept these agreements and
we'll do enter again for the install and enter again for default.
And enter again for that and then we'll go ahead and wait and I'll be right back.
Once this is done installing
right now it's going to install it we're gonna go ahead and hit no for this we don't actually need to
work with it.
We'll do reboot
so as we can see here we've loaded right back into the installer.
So what I want you to do is go and exit out and it's going to say send power off is going to do power
off the machine perfect click onto the essence settings storage.
We're gonna do is we're going to go ahead and click on our storage device so we added and we're gonna
go in and remove it OK and start the machine back up this way it won't boot into the installer any longer
it'll boot straight to upsets perfect.
Now that we're here what we're going to do is we're going to set up a few default things we're just
going to put some things in place.
So this says Would you like to set up lands or in this case wanting to type and hit enter.
We don't want to set any up enter the name of the wind interface or we're going to.
It says in 0 or a so we're not going to use a we're just going to use M0 or whatever option it provided
to you and then hit enter and then it says enter land interface name or a four auto correct.
So in this case I'm just going to not click anything which can enter and then do you want to proceed.
Yes so we'll go ahead and let that finish Perfect.
So once we're here we're going to hit a four shell
and then we're going to do if config like that in the left.
So you can actually see what's going on
OK everybody.
So there's one thing that that I goofed up on.
So if we can see here at if we go back to P.F. since we had settings and the network we need to change
this from Nat to bridge.
So what you can do even though this is running what I want to do is Glenn Close this power off the machine
settings that's fine.
Then you're gonna go into settings network change it from not bridged.
And when you do this.
Leave it whatever the default is that's gonna be your base network card that you're gonna be using whether
it's wireless or a phone based.
OK.
And go ahead and start it back up again.
And once all that's done it's just gonna pop us up back to the same thing but what it did was it changed
it from an IP address on the local network inside of the home where it provided us an IP address on
our actual network where the our physical machine were running this is actually sitting.
So I'll be right back with you guys want this finishes loading.
Now we've loaded up we'll do shell again if config like that in Dallas and then we'll see at the top
we see an eye net right here.
So I not in my cases 1 9 2 1 6 8 1 dot 12 so years is gonna be whatever is gonna be slightly different.
So go up to your browser do HDTV s 9 2 1 6 8 1.
Well I believe it was twelve Yep
perfect.
In my case it's not secure.
So all had advanced add exception in your case you might have to do something similar but this is what
happens with Firefox so good at the exception.
Perfect.
So now when you get here the default is admin and the password is p since P F S E N SD so that's gonna
get to our initial installer.
So what we're gonna do here is we're going to click next and next we're perfectly fine there.
So in this case we're gonna give it something or do.
P.S. since 0 1
since 0 1.
Perfect.
That's completely fine local domains fine DNS server we're going to leave empty for now.
We don't need it.
We're not going to need it in this particular video next.
And time server we're going to leave completely completely fighting and change the time zone or whatever
you want.
I'm leaving a default next.
OK so we will leave that as actually we're going to keep it on the page.
We're not going to play around with this at the moment.
So go next.
And then the admin password so this is where you change the PEP sense part to whatever you want.
And in my case I'll just change it to password
password.
Next and we'll do reload we'll just let that finish
Perfect and then we'll click finish
and accept.
So this is our base interface.
So we're gonna be going over this and a little bit more detail on the next video.
