Hello Dan, thank you very much for this clear and step by step config. Please keep up the good work by posting more videos on youtube that cover the ccna objectives. Many thanks. Riz
@MaximTheBeast It should. The NAT translations are on seperate netwoks. Neither network has any idea what the other networks IP address scheme is. It will only see the Public IP address. In the case of Overload it would see 200.10.0.1:239 (Note 239 is just an example of a port. Each time NAT uses Overload it gives the new host a different port identification.) When using Static NAT it you will only see the 200.10.0.2 IP address, as it is only able to translate for the IP address it was bound to.
really great, I learned more watching youtube than in lecture. Please do a dynamic NAT example. Preferable with a router on a stick configuration that is dhcping to various vlans.
Thank you for this video I couldn't for the life of me figure out why my dynamic nat wasn't working but i forgot its wildcard mask for the access list. The thing that got me is, PCb would still ping across just not with the NAT address since i put 255.255.255.0 as its wildcard mask.
great videos, learned more about nat in 20 minutes than wasting half a year in college.. also would've been nice if you'd incorporated a sub-interface tutorial in this one, could've shot two birds with one stone :)
@MaximTheBeast Sorry about replying twice, but there is a character limit. In otherwords there should be no issue with both sides having the EXACT same IP addressing scheme. The host could be 192.168.0.10 and the server could be 192.168.0.10 and neither of them would ever know. However I will point out that in the real world, the server would be in a DMZ and have a public IP address. So no NAT would be needed. Unless we get into VPN tunnels for servers on a companies intranet.
Another troubleshooting could be done by sh ip nat translations, that explains more clearly. But thanks for the video, it was very clear and informative.
Thanks for these videos, Dan. They really help me a lot. But I have a question. You need to connect a router to another router via serial cable to make the process of NAT? I tried to do with other interface and did not work.
awesome explanation and details. although i have an issue: after making exactly the configurations you have showed, i cannot ping from PC to Server..any idea why?
when I opened the inbound PDU on router R1-Satic-NAT , I notice that source IP add still as is , I mean the IP isn't translated to public IP 200.10.0.1 , whydoes the default route that you set in pervious lesson impact in this
Can we set Overload for the Server side? I have a PT, where the server side router is connected to a switch whereas 3 server is connected to it... I dun find it able to have the Computers to communicate with all servers if i have it setted on Static NAT, so i assume it would be overload.. but when i configure the overload, it doesn't seem to be able to communicate with the computers on the other side, But static works but only able to communicate with 1 of my servers.
Awesome video! Helped me out a lot! :) If you still here after all that years the video had been published. Can you help me out a little bit? I managed to connect the two network following the tutorial, but, under the R0 router, I have a level 3 switch with seven VLAN networks connected to it using l2 switches. Could you tell me how should I make the computers and servers in the VLAN networks find their way to the server on the other side? I am sure there is a way but all under my search I found notch, or not a notch, but no clear answers. :S Can you help me out?
nice job...question....What if the R0_Nat has a server connected to its fa0/1 port( server ip address within the 192.168.0.0/24 network)...do u also configure the port as "inside" or how do u go about it?
Hello There....Good Explanation about Static and Overloading NAT. And what about explanation for Dynamic NAT? Can you give me the link for tutorials about others topic as the way you explain form step to step as following: 1. AAA (Authentication, Authorization and Accountability) 2. VPN (Virtual Private Network) 3. Creating site to site VPN 4. Configuration Port Security 5. VLAN. Please respond immediately, I need a help for those.
hey dan one doubt !! here you created standard ACL closest to source to allow 192.168.1.0 n.w but i think we have to apply standard acl closest to destination right??? which is correct??
Been watching a lot of different videos while reviewing for my exam. You have the easiest most helpful ones so far. Kudos.
This has to be the simplest yet effective configuration of static NAT and PAT i have ever come across. Really helpful 👍👍
your explanation is very clear , and your accent is perfect , thanks a lot
I was really struggling with nat until I found your videos. These 4 videos made it very simple to understand and build my test lab.
Been struggling with this for days now using a mountain of books. Watched these four vids and now it all makes perfect sense. Dan, your the man.
video of 2011 and still most helpful in 2020 , great series of ccna , thanks
Excellent. Watched this series several weeks ago, and just came back to refresh today. Nice job explaining this.
Teaching is a skill, and Danscourses has it.
Man, I wish you were my CCNA teacher, and you are in a way. Thank you.
You make learning ultra easy. Well done!
thank you for the video, i had hard time understanding this till now, thanks for make it so easy
Thank you very much, very good teacher.
Hello Dan, thank you very much for this clear and step by step config. Please keep up the good work by posting more videos on youtube that cover the ccna objectives. Many thanks. Riz
Thank you so much for your videos. You really helped me in my college classes

thank you very much you're the best teacher ever you helped me
God bless you man for sharing in this much detail.
thank you Dan for all your videos , your the man!!
Amazing Tutorial..I started from Part 1
Great explaination
Great info, you are able to explain it very clearly, many thanks for that.
Your videos are all great! Thank you so much Dan!!
really great, I learned more watching youtube than in lecture. Please do a dynamic NAT example. Preferable with a router on a stick configuration that is dhcping to various vlans.
Its pretty straight and simple thanks to you
Correct, for the CCNA, in a standard ACL, since there is no ability to set the destination, you need to apply the ACL closest to the destination.
Thank you so much this was very helpful!
Thank you for this video I couldn't for the life of me figure out why my dynamic nat wasn't working but i forgot its wildcard mask for the access list. The thing that got me is, PCb would still ping across just not with the NAT address since i put 255.255.255.0 as its wildcard mask.
Man your awesome. You made it very clear. Thanx
thanks.....you are the best teacher...
amazing tutorial easy and clean, thank you so much!
Thank You very much for precise explanation
....
great explanation and to the point thanks!
Thanks! It is really helpful! I like your videos so much.
This stuff is beyond perfect review.
great videos, learned more about nat in 20 minutes than wasting half a year in college.. also would've been nice if you'd incorporated a sub-interface tutorial in this one, could've shot two birds with one stone :)
Great work!
thank you very much, fast clear
Very very professional, Thank`s a lot

Great explanation as always, thanks a lot!
this is super helpful
OK
Thanks so much a great Job
Thank you! It's really clear.
thx a lot for this tutorial, it was helpful.
Great tutorial, thank you
Great information..!!!
Thanks for these videos, Dan. They really help me a lot. But I have a question. You need to connect a router to another router via serial cable to make the process of NAT? I tried to do with other interface and did not work.
You r the best........!!
Dude ur the best
Very well explained! Thanks a lot.. :))
from this moment i understend NAT
Great video! thank you!
Mahalo Dan!
Salute To you man...God Bless You...and keep up with the good work :)
Grateful
really good explanation. helpful! +1
awesome explanation and details. although i have an issue: after making exactly the configurations you have showed, i cannot ping from PC to Server..any idea why?
thanks alot
This is great!
Question.
How do I ping pc 0 from an outside network?
when I opened the inbound PDU on router R1-Satic-NAT , I notice that source IP add still as is , I mean the IP isn't translated to public IP 200.10.0.1 , whydoes the default route that you set in pervious lesson impact in this
Thanks for the usefull information :D
Absolutely fantastic... Please can you tell which sofware can i use to simulate IP Address Spoofing Attack?
Thank you sir know-a-lot
For me NAT doesn't work, I have Vlan and intervlan routing, HRSP and ospf running on my configuration, could this be the reason it's not working?
Thank you sir
Thank you
It's Perfect. Thanks alot ;)
what if you have more than 2 routers, how would you do the ip route?
Thank you....you have any plans to upload VPN, MPLS, BGP tutorial videos???
Can we set Overload for the Server side?

thats good
man thx a lot u are awesome . can you make a video for multicast routing and delivery
Awesome video! Helped me out a lot! :)
If you still here after all that years the video had been published. Can you help me out a little bit?
I managed to connect the two network following the tutorial, but, under the R0 router, I have a level 3 switch with seven VLAN networks connected to it using l2 switches.

In that same scenario i have config when i am ping to server-side reply is request time out
👍👍👍👍👍👍

Sir when you will upload ccnp videos
hey dan one doubt !! here you created standard ACL closest to source to allow 192.168.1.0 n.w but i think we have to apply standard acl closest to destination right??? which is correct??
Standered acl u have to apply near destination & extended acl near source.
what does the overload command do?
why I can not ping server
same here
