So is dynamic not once again you are creating a pool of inside global traces.
The reason why it's called dynamic rather than static is the rodded dynamically allocates IP addresses
from the pool on a as needed basis.
The mapping will be removed once communication ends.
So there's no permanent one to one mapping that's always wé like you have with static Nat with dynamic
nat the net translations are automatically created when they needed and torn down or removed to were
not needed.
Now as I've been explaining typically static Nat is used when you have servers so a way road one is
a serve as an example that needs to be accessible from the outside or Internet not just to make sure
that we cover the topics in the CCMA.
I want to show you that Rato one is able to ping router three when static net has been configured on
Raiatea.
So show run piping clewed that we can see the static NAT translation here.
So we are translating 10 1 1 1 2 8 1 1 5 show IP net to translations.
Notice there is our static NAT translation.
We are not netting the outside local and outside global in the static Nat let's do a debug.
So debug IP Nat and what I'll do now is our telnet to 8 1 1 2 the telnet connection is disconnected
because I need a password on the site.
But what I'd like you to see is the source IP address 10 1 1 1 was not 2 2 8 1 1 5.
That's the inside global address.
The destination of the traffic is 8 1 1 2.
We had a reply back from 8 1 1 2 2 destination 8 1 1 5 which is then translated to 10 1 1 1 so traffic
from a 1 to 3 is having the source address translated and then the return traffic has the destination
address translated.
We are doing source address translation of this IP address all enable telnet on the site.
So they enable the V T1 lines on this router
and enable a enable password.
So we still running a debug show debug shows me that debugging is enabled and old telnet from wrote
a one to rotisserie again.
You can see the net translations taking place again source to destination.
I'll log in
and let's end to one character.
E.
You can see for the character e the source was translated from 10 1 1 1 2 8 1 1 5 going to a destination
of 8 1 1 2 reply came back and some other traffic was returned.
So an acknowledgement to rotisserie type an we get to the same kind of translation hit enter same kind
of translation is taking place.
So for every character that I'm into in the last session nocte translations are taking place with 10
1 1 1 being translated to 8 1 1 5 for traffic going from inside to outside and then 8 1 1 5 is being
translated back to 10 1 1 1 4 traffic from the outside to the inside.
In this example we'll configure dynamic not in the typology we have to rodders route 1 and route a four
that are on the inside.
They are connected via a switch to Rodda 2 which is going to do the actual network address translation
will configure dynamic not on Rodda to to allow both route 1 and route of 4 to access router 3 which
in our lab is deemed to be the Internet.
So the 8 network is on the outside.
That is the internet 10 1 1 0 is our internal network with these three devices connected to each other
via switch one later on I'll expand the typology to actually connect rotisserie to the Internet so that
Rotto one and radio 4 can connect to sites such as Google dot com.
