6.6.7 Packet Tracer - Configure PAT

hi friends welcome to world in this video we are going to solve this packet tracer activity configure pat that is port address translation before coming to this activity friends if you like to get any ccna version 7 online support or any technical support you can contact our team using our website link you will get from the description below and also if you like to get these type of technical videos in future consider subscribing and don't forget to enable that bell icon so that you will get notification message whenever we upload a new video now coming back to our activity here we can see the objectives part one configure dynamic net with overload party to verify dyna dynamic net with overload implementation part 3 configure path using an interface part 4 verify pad interface implementation coming to part 1 configure dynamic net width overload step one configure traffic that will be permitted on r1 configure one statement for acl1 to permit any address belonging to 172.16.0.0.16 so we are going to create this standard access list and we are going to permit this network 172.16.0.0 coming to our topology here we can see that network private network 172.16.0.0 networks so here we are going to create the success list in this r1 enable configure terminal we will give in short current t and here we will create the access list 1 and we will permit this network 172.16.0 0 then we have to give wild card mask i'll put a question mark here so that we can see what is the next while the card bits it's a 0.0.255.250 step 2 configure a pool of address for nat configure r1 with a net pool that uses the two usable addresses in the two zero nine dot one sixty five dot two hundred or two thirty two slash thirty extra space so here we can see that command the given uh ip nat then they created this pool any underscore full underscore name so we can give any name for that then uh 209.165.200.22 sorry two three three and two three four then we have to specify the net mask so we will give this configuration in this router r1 coming to the configuration in r1 here we will give that ip nat pool here we will create the pool okay i will give my underscore pool then we will give the address i'll put a question mark and here we can see we have to specify the stat ip address so as they specified it's a 209.165.200.233 then we have to give the end ip address so we can verify that using a question mark uh give space then question mark then we have to specify end iep address just i will copy this address and paste here then edit to this 234 then we have to give the net mask it's a 255.255.255.252 step three associate acl1 with the nat pool and allow addresses to be reused so here we have to give this command ipnat inside source then specify the list that is one then pool we have to specify the pool we created overload so we will give this command in this r1 we will go to this router r1 and we will give that command here ipnet inside source list 1 pool then we have to specify our pool name it's my pool my underscore pool we have to give overload step 4 configure the nat interfaces configure r1 interfaces with the appropriate inside and outside net commands so um here we can see coming this topology here we have this interface serial zero slash one slash zero which is connecting to internet and this is um uh net outside ip net outside and here we can see uh these two interfaces gigabit the third zero slash zero slash zero and gigabit ethernet zero slash zero slash one which is connecting to this lands they are ipnat inside we will give that command in r1 we have to go to those interfaces one by one interface serial zero slash one slash zero and here we will give ipnet outside now we will go to a gigabit interfaces interface g 0 0 0 this is i p net inside then we have a interface g 0 slash 0 1 i p nat inside now coming to part two verify dynamic nat with overload implementation step one access services across the internet from the web browser of each of the pcs that use r1 as their gateway they are pc1 l1 pc2 and l2 access the web page for server 1 where all connections are successful we will test that here we will get the ip address of this server one in this internet we will go to pc1 web browser and paste that ip address here in this url and click go and here we can see server one we get the web page we will go to l1 web browser paste that address we get the web page go to pc2 web browser and here again go be able to access the web server finally coming to l2 paste that ip address here then click go perfect so be able to access the web page from this server in this internet so we have seen all connections successful coming to step 2 view net translations view the net translations on r1 we have to give this command show ipnet translations notice that all four devices were able to communicate and they are using just one address out of the pool pat will continue to use the same address until it runs out of port numbers to associate with the translation once that occurs the next address in the poll will be used while the theoretical limit would be six five five three six since the port number field is a 16 bit number the device would likely run out of memory before that limit would be reached okay that's fine so we will give this show iep nat translations command in r1 so that we can see the translations end show ipnat translations and here we can see all the translations here we can see in cd local address the private ip address of all these edge devices here we can see that and this is the port number they used and here we have a inside global right and we can see they used this public ip address to go to the internet and here we have outside local and outside global now we will go to part three configure path using an interface step one configure traffic that will be permitted on r2 configure one statement for acl two to permit any address belonging to 172.17.0.0 16. okay here we are going to create the access list in this router r2 and we have to permit this uh private networks 172.17.0.0 we will create this success list 2 in this router r2 enable conf t we will create access list 2 and we are going to permit 172.17.0.0 and here is the wild card mask 0.0.255.255 step 2 associate acl2 with the nat interface and allow address to be reused enter the r2 nat statement to use the interface connected to the internet and provide translations for all internal devices so we have to give this command i p nat inside source list 2 so this is the access list we created then interface serial 0 slash 1 1 which is connecting to this internet here we can see that yeah overload we have to give the command overload we will go to this router r2 and here we will give that command ip nat inside source list 2 interface is a serial zero slash one slash one overload step three configure the net interfaces configure our two interfaces with appropriate inside and outside net commands so coming to our topology here we can see this interface serial zero slash one slash one ip net outside and here we can see these two interfaces g zero slash zero slash zero and g zero slash zero slash one they are in um inside i p nat inside we will do the configuration we will go to interface serial zero slash one slash one and here we will give ip nat outside then we will go to interface g zero slot zero slash zero i p nat inside also we have interface g zero slash zero slash one i p nat inside now in part four verify pad interface implementation step one access services across the internet from the web browser of each of the pcs that users are two as their gateway here we can see those devices pc3 l3 pc4 and l4 access the web page for server one where all connections successful we will check that here again i will copy the iep address of the server one then we will go to uh each pcs first of all we will go to pc3 web browser and here we can paste that ip address we copied and here we can see be able to access the web page coming to l3 a browser paste that ip address the ip address of our server okay then go to pc4 here also be able to get the webpage from the internet coming to l4 go perfect yes all connections successful step 2 view net translations view the net translations on r2 we can verify that we will go to r2 and we will give the show command givent show ipnat translations and here we can see the translations inside local here we can see the private ip address and this address will not be routed in the internet they use this inside global address here we can see that address also we can see outside local and outside global step 3 compare net statistics on r1 and r2 compare the nat statistics on the two devices why doesn't r2 list any dynamic mappings here already we have seen the output in r1 as well as r2 and when we compare mostly we can see the output are same uh because uh here one by one be accessed this server right so if you access uh from the different devices at the same time then you can see this dynamic mapping so just i can say the difference between this dynamic mapping and this path here in this uh r1 it list dynamic mapping for the poles of addresses we created right in r2 r2 is only using the outside interface address so that is the address of this interface serial zero slash one slash one perfect so here we sold this packet tracer activity configure path and here we can see our completion status it shows hundred percent now dear friends if you have any doubt any suggestions regarding this packet tracer activity uh you can comment below or you can contact our team using our website link you will get from the description below and also if you like your video give a thumb and share with all your
