NAT basics for beginners CCNA - Part 2

Download the Packet Tracer 6.3 file in the video at:
danscourses.com...
- In Part 2, I cover NAT overload translation or PAT, and dynamic NAT using a NAT pool of public addresses.
- In Part 1, I cover all of the basics regarding NAT and how to configure it for the CCENT and CCNA certification exams. The video demonstrates static NAT translation, and port forwarding.

17 YEARS ... I've been waiting for a CLEAR... NAT explanation from Cisco! Thank You Sir for helping CISCO!!! Cause they really SUCKED at explaining THIS! ;-)))

[@danci947]

I guess it's normal that I don't get it from the CCNA material then. Wow, 17 years!!! They really need to update this

[@leo-rq2ei]

I've watched videos from a lot of teachers but when I don't understand something I watch yours and poof. thank you

[@TheRealDealVideos]

Dude, you have the best channel on YT. Thanks for helping us this much.

[@timenkompagne7402]

thanks for the perfect video of configuring and implementing NAT/PAT. better described than in the CCNA

[@nnickoss]

Just great! After finishing the video i was finally able to understand NAT.

[@ralphsanchez5205]

simple explanation for a simple understanding that's all i want and i've got it from you sir. thank you so much Dan for giving efforts on this.

[@cutesammie]

Thanks a lot for the clear and concise explanation to the supposedly simple concept that Cisco made so confusing!! I'm talking about the outside local and outside global terminologies.

[@abdulsamad-dp6oz]

great lesson ever I watched for NAT

[@ahmedrb1587]

Dan, your lessons are so easy to understand....Really well explained. Thanks a lot. Why dont you have a premium Cisco training products for CCNA, CCNP where we can purchase and go more in depth

[@geoffalcorn4727]

Youre a legend Dan, I learn so much easier from your methods and delivery than anyone else. I thank you Sir, go raibh maith agat mo chara

[@blorb112]

The ping from PC 1 (10.0.0.100) to PC0 (192.168.1.100) would have worked regardless of the NAT overload configuration -> due to the default route

[@blacknova6895]

It's been a while since i did cisco but damn i remember it being alot more boring but this is the most fun in cisco i had in ages.

[@johnorbe764]

thank you so much, Sir! your videos are clear and very easy to understand.. thank you again!

[@mark3105]

I was struggling with NAT until I saw this. but now I have finally am able to wrap my head around it thank you so much

[@fatimaal-zahraa1618]

I swear this saved my life! thanks a million!!!!! :')

[@jamshidgolbakhsh5981]

It was great tutorial and very well explained, thank you very much for your hard work.

[@Nmoor101]

such an amazing explanation

[@synysterziq]

YOU ARE A LIFE SAVER ! THANK YOU

[@TamImBlessed]

Many years gone by, and your videos are likely still the most vivid explanations to so many Cisco topics practically.

[@eng-gamaraldeenalshaikh8044]

thank you very much for helping us usually so useful material

[@davidadams2395]

Incredible! I was afraid I wouldn't understand NAT and all its features, but your careful instruction, coupled with my writing it all down as I went along, made this simpler to comprehend than I had thought. Thank you!

[@insightsmundoafora]

Thank you so much for sharing, that's an amazing LAB!!!

[@slamtoo11]

Thank you For ur videos very easy to understand. I tried the Lab but I had an issue with (YouRouter) the Pool config. When I do Sh IP NAT Translations I don't see anything. I doubled check my config everything seemed to be correct. Interfaces configured correct same as the ACl and Pool. Can you please advise? Thank you so much From Morocco.

does anyone no if the cloud is the Cloud-PT option you choose from ?

[@vainilk78]

[@artursradionovs9543]

Question - whats the cloud configuration? do you know how to connect dsl too?

[@ludwinsouls3051]

Genial, Todo Entendido. Gracias. Thank you

[@danielruzicka3858]

Or why it has to be inverted ?

[@droidcrasher]

One thing I can't explain.... WHY IS IT when checking the SHOW IP NAT TRANSLATION output after OVERLOADING... The output shows WELL KNOWN PORTS INDISCRIMINATELY!??? How is this possible !??? Port 21? Is FTP Port 22!? Is SSH Port 23!? Is Telnet AND SO ON !!! CONFUSED !!!

[@tharindusathischandra9533]

You are doing a lot of good stuff. But, I'm wondering why don't you have a GitHub repo with all packer tracer files and packet tracker log files included?

[@Strange19665]

thanks for your videos, they are really helpful. For some reason after i put the nat overload, the show ip nat tranlation is not woking, the code runs but doesnt show anything

[@danscourses]

Did you setup routing> I think I used default static routes in the video so the routers know to forward the packets. Also check that you have the router interfaces configured with ip nat inside and ip nat outside

[@Strange19665]

@@danscourses Thx for your fast reply, yeah ur right, I had subinterfaces created, I need to assign them aswell as outside or inside lol

[@kornelious1]

How do you have the routing setup between the routers? I would like to set this lab up in my gns3 lab. But you never show how they are communicating or how routing is setup.

[@markman3031]

Man thank You very much, I am stuyind IT and Cisco at my school and this was very helpfull, also I am doing CCNA :D

[@joshuabarbosa4824]

Sir, How would I ping a pc that is translated under pat? Is it possible to do so?

[@lolipop1970]

I'm wondering the same thing.

[@mustafakaddour7959]

This one make me crazy hhhh

[@mustafakaddour7959]

Any answers??

[@johne650]

They could ping already anyway because you have the routes all statically routed using a summary network.

[@tsim7188]

yep for sure... this is the comment i was looking for.. because i was getting confused

[@johne650]

No problem, you're very welcome.

[@mustafakaddour7959]

Yep.. I was wondering also how he can ping the local ip from another local ip.. It's impossible

[@jakurdav]

jesus, you are such a good teacher that you make me feel bad for not taking more interest about for CCNA class at my uni. wonderful content mate, thanks for explantion!

[@bellewolde]

This helped me a lot!!! THANK YOU!!!

[@motiondesign2501]

i have a question about the bit input the serial interface to start, I have ping from my pc (ping 1.1.1.2 -l 1000 -t) on the other router (WAN CONNECTON) and when I'm on the router that I ping him with the show interface serial command 1 / 0 and in (30 second input rate 0 bits / sec, 0 packets / sec) I received only 8000 bits while than the transmission ping contunu (ping 1.1.1.2 -l 1000 -t), but why I always receives 8000 bits and my ping always contunus.

[@zsoltpal7905]

excellent, thank you!!

[@torresattaluri]

Dan Thanks a lot....

[@brod515]

Thanks for the file made it a lot easier to follow. Is there a way to do this without the CLI interface, in the config you can create IP routing tables but you can't do NAT.

[@mahuubao]

Excellent ... well done ...

[@chrisgast]

With PAT, how is it translated if one inside global IP is used for many inside local IPs with the same port?

[@boots7859]

Dan, 10 years and this is the easiest and most concise explanation of NAT I've ever seen! Subbed, and have to check if you have more videos. Thanks!!!

Man, I need to up my game with my CCNA studies. For me it's all about retention. I understand the concepts, and the practicum, but you sure make it look so darn easy while I have brain cramps just trying to remember the Cisco commands. You do such a great job explaining your CCNA knowledge.

[@jamesdossantos1840]

Really enjoyed this LAB and it really helped clear up all my questions I had for NAT.

the router on the other end just rejects it every time. smh

[@rakib17874]

When we configure single ip. Local address statically we permit just inside local ones but when we use pool we would use global addresses , is that it ? Help me guys🥝😫😫

So when do we use ip nat outside source list?

[@SundayRide1204]

are you using a routing protocol or is NAT it's own routing protocol? I'll download the file tomorrow in case you're busy and cannot find time to answer. TY for the video!! great material for sure

[@danscourses]

I forget if I used static routes or a dynamic routing protocol. NAT is not its own routing protocol it is typically used only for translating public to private addresses and vice versa when the packets pass through the router

[@nem81]

You have static routes in the example file :)

[@esnanambeau2900]

Thanks a lot

[@markcp350]

awsome! totally like it

[@ragnarjoemaa8109]

Amazing

[@anemicgoalhop495]

I think your definition of "for beginners" is different from mine.

[@danscourses]

I apologize Anemic. I do have a CCNA 1 playlists which is a better place to start.

[@anemicgoalhop495]

OK, thanks, I'll start there.

[@sangoku116]

I'm not too sure why but when I do the access list command I get this access-list 101 permit 10.0.0.0 0.0.0.255 ^ % Invalid input detected at '^' marker.

[@Tobbit]

maybe you're using extended access-list. change 101 to something less than 100

[@TheDave000]

You are trying to create a standard ACL. This needs to be numbered upto 99. 101 would be an extended ACL, so the command is expecting a TCP/UDP statement. Number it anything from 1-99 and the command will work.
