6.4.5 Packet Tracer - Configure Static NAT

hi friends welcome to world in this video we are going to solve this packet tracer activity configure static nat before coming to this activity friends if you like to get any ccna online classes or any technical support you can contact our team using our website link you will get from the description below and if you like to get this 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 back to this activity here we can see the objectives part one test access without net partition configure static net path three test access with the net we will go through the scenario in ipv4 configured networks clients and servers use private addressing before packets with private addressing can cross the internet they need to be translated to public addressing servers that are accessed from outside the organization are usually assigned both a public and a private static ip address in this activity we will configure static nat so that outside devices can access an inside server at its public address coming to the instructions part one test access without net step one attempt to connect to server one using simulation mode switch it to simulation mode then from pc one or l1 use the web browser to attempt to connect to the server one webpage at 172.16.16.1 continue to click the capture forward button notice how the packets never leave the internet cloud the items should fail coming to our packet tracer here we can see simulation we will click on simulation then close this simulation panel now we will access pc1 or even you can access l1 then we will go to web browser and here we will give this address 172.16.16.1 so here we will click capture or forward and we can see it's failed even we will try to access this webpage using this public ip address 64.100.50.1 from anyone of this pc uh i will go to pc one desktop then the browser here we will give a 64 dot 100.50.1 then press go and we'll give a capture or forward so it's failed and we are not getting the webpage here in pc1 here we can see it says request timed out then exit simulation mode okay we will go to real time from pc one ping the r1 serial zero slash zero slash zero interface here the given that ip address we will copy it the ping should succeed so we'll go to pc1 then we will go to command prompt ping to that interface and we can see we get the replies next we will go to step 2 view r1 routing table and running config view the running configuration of r1 note that there are no commands referring to nat an easy way to confirm this is to issue the following command show run then include nat so we'll go to r1 enable here we will give that command show run include net and here we can see there are no commands referring to nat in this router r1 now verify that the routing table does not contain entries referring to the iep network addresses for pc1 and l1 verify that nut is not being used by r1 using this the show command show ipnat translations again we will go to r1 and we will give this a show command show ip nat translations and here we cannot see any entries next we will go to part two configure static nat step one configure static net statements refer to the topology create a static net translation to map the server one inside address to its outside address here they given the command ip nat inside source static 172.16.16.1 then a 64.100.50.1 we will configure this static nat in this router r1 we have to go to a global configuration mode config so here we are going to give ip nat inside source static then we have to specify the ip address 172.16.16.1 so here i will put a question mark and we will see what is next we can specify inside local ip address so here we are going to specify this inside local ip address 172 dot 16.16.1 again space question mark then we have to specify inside global iep address so as the specified we will give a 64 dot 100.50.1 step 2 configure interfaces configure the g 0 0 interface as an inside interface we have to go to that specific interface uh g 0 0 and we have to give this command i p and nat inside and in this topology we can see that interface g 0 0 which is connecting to this switch s1 so coming to r1 we will go to that interface it's a g 0 0 and we have to give this command i p nat inside then configure the serial 0 0 0 public interface as an outside interface so here we can see this interface serial 0 0 0 which is connecting to this internet so we'll configure as outside interface again we will go to r1 exit from this interface then go to interface serial 0 0 0 and we have to give ip nat inside sorry it's outside now we will go to part three test access with nat step one verify connectivity to the server one of the page open the command prompt on pc1 or l1 attempt to ping the public address for server one ping should succeed then verify that both pc1 and l1 can now access the server one webpage we will go to pc1 and we will try to attempt to ping the public uh address for this server one okay we'll go to pc1 command prompt here i will ping to using a public ip address so we have to give a 64 dot 100.50.1 then press enter we can see we get the replies verify that both pc1 and l1 can now access the server one web page so coming to pc1 we will go to this web browser and here we will give a 64 dot 100.50 then press go and we can see be able to access the webpage same way we will go to laptop a browser and paste that url okay be able to access the webpage in step 2 view net translations use the following commands to verify the static net configuration on r1 show running config show ipnet translations then show ipnet statistics so coming to r1 we will give end show running config here we can see the net we created then coming to the interfaces g 0 slash 0 ipnat inside outside next we will give show ipnat translations and here we can see the translations protocol used a tcp and we can see inside global ip address inside the local address then outside local and outside global here we can see this inside local this is the private ip address for our web server it is server one then here we can see this uh inside global address 64.100.50.1 this is what we given here in this ip nat inside source static sure what we given 64 150.1 also we will give this a show command show ip nat statistics and here we can see total translations it's for outside interface is serial 0 0 0 then inside interface is gigabit third 0 slash 0 okay that's all in this activity that is a configuring static net now dear friends if you have any doubt any suggestions regarding this factor tracer activity please comment below or you can contact our team using our website link you will get from the description below and if you like your video give a thumb and share with all your friends stay tuned and we will meet again with the next video thank you
