Static net concept, an example.
So basically, what is a static net static that we call it one to one mapping between internal and external
IP?
So basically, for example, most likely we use when we have this kind of situation where we have a
one source, one public private IP range, one private server, one server, which is which is 190 to
168 people, not one.
It has a private IP range.
It is not visible on the Internet.
And you want to access from outside, let's say maybe it is a DMZ server.
This may be a VPN or this may be or an email server or anything like that.
The range inside the DMZ is a private but outside world does not know the private IP.
But that is why what we need to do, we need to configure this as a one to one.
So basically, every time we hit from the outside and hit two, 200 to 250 for that 11:00, it will
be translated back into 192, 168 people, one on one and vice versa.
OK, so any traffic between these two, any time you hit from the server, going to the firewall and
then hitting the server, it will be going through the.
To these all the time, the problem is the pattern that actually we can see, we do not have any control,
whatever the apparatus is configured or the pool of vibrators is configured, it always used that IP.
But in our case, we want to always specifically asking for a getting coming from the outside.
Any sort IP on the world.
For example, you use Google every day, use Google, YouTube, Facebook, LinkedIn and all those things.
These were actually, for example, if I go to the net.
And I try to bring, for example.
This is a BBC reporter.
OK, so basically you see outside where No.
Two, one, two, 58 to 37 to 54, these are publicly known Iapetus.
But what is happening from my machine, I am trying to access this public server IP.
But behind the scenes it is there is a firewall end.
The behind the firewall, there's a private range.
IP addresses are available.
So basically the benefits are to No.
One.
We can use these.
We can access the server remotely from the outside world.
And second thing is that these servers are providing the security.
Nobody knows the actual private IP addresses for them.
So that's the concept of starting it and another thing in the setting that can keep in mind this static
match point of view.
Stating that point of view, that what happened in the setting, that the society will never change.
So basically we called a destination kind of at the society, for example, is coming from two hundred
one dot 165 100.
Or when we when I am accessing these server from my machine and from your machine, you you guys have
your own public IP addresses.
So basically in the source, when the traffic is going from the other landside to our our Internet site,
we can see that our source, IP 10.1 dot eleven hundred was changed into two hundred one or two.
Fifty four also outside.
People know that actually they are not talking to the private IP, they are talking to the public IP
in case of a static that most likely the static source IP will never change.
So that's a difference between society and destination source and destination that in the source that
source IP will change into different IP so the outside world can know what is going to happen.
For example, most likely our wireless router where we are all connected to a private equity and the
outside, when we go outside, we use the wireless Internet router microscopes and it happened in that
market.
Actually, that's called dynamic net or dynamic that something like that.
But in the case of static, that most likely your private IP, your your source IP will never change
because there are hundreds and millions of people accessing because you don't order the UK on the same
day.
However, the destination that will be changed.
So basically we will hit the two hundred to fifty four point eleven, which will be translated back
to 100 to 168 11. one on one.
So basically in that situation.
When the IP addresses change from not from the source, but to the destination, we call the destination
dead, and that is a that is the main thing in the static not happening in the static net source.
IP does not change in the dynamic.
Not that bad.
Actually, the source IP will change eventually, and that is the whole benefit.
So whenever you are inbound traffic coming from the outside into the into your firewall and going into
the BMV, we call a static net, which is a one to one mapping between a server.
When you want to expose one of the server to the outside world, it's called destination.
That is one because destination IP will change another source IP.
I hope all-Clear.
