[@prasadjeyapalan5694]

Hey Jeremy, Just want to thank you for helping me pass my CCNA. I have been following you for the last 8 months. I listen to your videos on my drive to work which is about 1.5 hrs each way. All those important information you give out helped a lot. I am going to buy your course and donate it to someone. Keep up your good work because you are helping a lot of people.

Hi Prasad, thank you that's very generous! I'm glad you like the course :)

[@ZeroGOA]

Hy Jeremy I want to thank you at this point. I passed the CCNA and that is mainly thanks to you! Even with the language, even though English is not my first language (i am from germany), I never had a problem following or understanding you, which is not always the case. No matter what other courses are out there, none compare to you, free or not. Also Neil Anderson you keep promoting even though he did a great job too. I would also like to note at this point that I am a career changer, actually I have been a physical therapist, but even for me you explained it so well that I passed the CCNA. Despite the fact that I have already passed the CCNA, I just bought your course as a thank you to support you a little. I will still continue to watch your videos and look forward to the announced CCNP track :) Thank you very much! Sorry for the long text, here is also no potato -.-

But even in his course not everything is covered 100%, in the CCNA are always individual questions that are asked, which are not even in the official documents. But with the mixture of Jeremy and Neil it should be enough to pass.

[@Rjoh121]

Until now, NAT and PAT were my weakest points for CCNA. Now, with your explanation, I feel more confident for the exam. Thank you so much, if I pass the exam, I will really appreciate your help!

[@kensrensen100]

If anyone wants some more details on why "your ISP will drop the packet" Here they are; When you own/rent a public subnet from an ISP, that subnet is routed to only you. That's why the internet works, every continent has an organization who has a range of IP's, those IP's are redistributed to ISPs, and ISPs distribute them to customers, and make the public networks using routing. Private IP's are not routed anywhere over WAN because they are private IP's. Nobody owns them. Your ISP will drop the packet because the ISP's router doesn't have any routes for the private IP ranges. This explanation is also quite simplified, but i think you get the picture. To demonstrate this in these labs, Jeremy has just not added routes to the RFC1918 private ranges on the "ISP/Internet" routers.

[@ambazack]

[@リンゴ酢-b8g]

diabolical detail to help you decide whether the question is about PAT or ordinary NAT. notice the ephemeral port number after inside global: 49912 for the netsim question. that's a dead giveaway that the question refers to PAT and not simple nat.

[@orusama86]

Hi Jeremy. Thank so much for those videos and the time you spent maing them. I want to ask something about quiz 2. You said that the problem with the first answer is that the pool last ip address doesnt fall into the /25 subnet. Isnt it also a problem that the acl denies while the 172.16.1.0 subnet while it should permit it?

[@JeremysITLab]

Yeah you're right about that, that's also a problem! Forget to mention it.

[@sumerianman6925]

Thank you Jeremy. I teach Cisco networking and I recommend this channel to my classes.

[@zb-JLion]

Hello Jeremy, I am afraid if I am repeating this question regarding Quiz 2 , is the sub-net mask out of range the only reason why option 'A ' is failed to be the correct answer how about the access list it is a deny statement or there is permit any entry that didn't show up here. its just a bit ambiguous for me. video time stamp 29:39 thank you!

Just a quick note that question number 2 on the quiz has a Deny line allow for answer A. Making it extra incorrect.

[@tamrick79]

I was wondering if anyone else saw this.

[@Aat8974]

at 14:59 i did a search and found the router changes the port number for every session, regardless of whether two devices share the same port or not, even if the device's original source port is unique

[@sergeinic1856]

22:35 - What's wrong with A? I suppose the main reason is the word "deny" in ACL, not only the pool subnet mask.

[@misterribal]

Hi Jeremy! Thank you for your courses. I have multiple questions: - can a router run static nat and dynamic NAT or PAT at once? - can connected routers run NAT? Therefore creating a 2-level NAT - if so, do RIP/EIGRP/OSPF still work? Are the LSAs affected by the NAT? Thanks!

[@JeremysITLab]

Hi! As for your first question, yes you can run multiple kinds of NAT at once on a router. For the second one, I'm not sure exactly what you're asking. A packet can be NAT'd twice, by one router and then by another, if that's what you're asking! Not sure about the third one, I think NAT could cause some problems but I've never tried it. RIP/EIGRP/OSPF are IGPs, used to share routes internally, whereas NAT is usually (but not exclusively, of course! )used for connections to external networks like the Internet. I'd have to try it.

[@misterribal]

@@JeremysITLab alright thanks Jeremy, that was indeed my question. Cheers!

[@whatever87-87]

25:22 the packets will not be translated by R1, but will be forwarded ? using which public ip address ?

[@JeremysITLab]

They will be forwarded as-is using their private addresses. This means that the ISP will probably drop the packets

[@kagelikedmonds5741]

your videos are by far the best ones I have studied. even better than my paid courses. thank you :)

[@JeremysITLab]

Thanks Kagelik :)

[@TheDebasmita7]

For question2, I thought since the acl was set to deny, thats the reason for it to be incorrect. Is this reason Ok?

[@RedFortress]

2:15 How is the packet destined for 100.0.0.1 routed to 203.0.113.1 ? How is 203.0.113.0/30 a matching route? Or does there have to be a static route to 100.0.0.1/32?

[@Heeby-Jeebies]

100.0.0.1 is the assigned internal global IP address for the host. When the packet reaches the router, it leaves via the outside port which has the address of 203.0.113.1.

[@justfahmi6948]

Hi Jeremy, I would like to ask something about dynamic NAT, supposed the source address is not permitted by the ACL, the source address wont be translated by the router but the packet wont be dropped, does this mean the private source address will be travel around the global network or there is some kind mechanism that will reject this packet with private source address? Thankyou in advance

[@myxbigxfruitxstickx]

from what i understand. the ISP will drop the packet since it will be using a private ip.

[@Futureone]

@ 5:45 you stated if the source IP is denied by the ACL, the source IP will NOT be translated. *The traffic will NOT be dropped! So what happens to the source IP address then when the router receives it if there isn’t a NAT configuration on it?

[@JeremysITLab]

If you haven't configured NAT, it will forward the packet without translating the source IP address. The ISP router would then drop it, but we're talking about R1 here. An ACL only filters traffic if it's applied to an interface. The ACL used in NAT doesn't filter traffic, it identifies which traffic should be NAT'd.

[@Futureone]

@@JeremysITLab ok, thank you. I got confused thinking once it went through R1 it needed to be translated because the other side was the internet.

[@murtuzahussain2236]

You mentioned the packets from ip's which are denied by ACL are not dropped but are just not translated. So how do they actually contact the outside world? Do they communicate with their private IP without getting translated to public? like in the example lets say 192.168.0.167 (private IP) do not qualify for ACL and is not translated then does it advertise itself to the outer world as 192.x.x.x instead of public 203.x.x.x?

[@JeremysITLab]

If it's being sent over the Internet, the ISP will drop the packet

I live in a hostel, and it is very common to not have access to internet. I have to disconnect / reconnect, and then when luck strikes, I get access to internet. I think this is dynamic NAT. Probably they don't have enough inside global addresses, as I can see on my Laptop, I am using a private Ipv4 address.

[@DimisChristoglou]

hey jeremy i want to clarify something , you said that we have to map inside local add to inside global add right ? in 26:13 you checked C thats because 203.0.113.62 is the only public ip ? because it is an external interface

"even though the ACL denies the packets, it doesn't mean the router will drop the packets, it just won't translate them" Yes.. the router does drop the packet, and typically sends an ICMP "destination unreachable" response, as a courtesy. Where else would a denied packet go?

How exactly would you reach such a scenario where a packet isn't dropped or translated? Think carefully about that and you'll probably reach the answer on your own.

But what happens if the destination host is also located behind a router that performs NAT ? Meaning how would hosts of R1 reach the hosts of the other router which is also performing NAT for its own hosts ? We can‘t use Private Address of those hosts as they won‘t be carried over the internet. and we can‘t use public address because how would the receiving router know which host the traffic belongs to. Can someone help me how it would work in that scenario ?

Hi, Jeremy, what PAT configuration should i use if i have given a different public IP addresses to use in a single pool? For example: 100.83.67.1 100.55.29.3 100.223.13.100 3 different public ip addresses which is not on the same subnet? is there a way to configure it?

Can DHCP still be used when using NAT? Thanks

[@JeremysITLab]

Try it in packet tracer!

Hello, is it possible to configure Nat Dynamic and Dynamic Pat on the same router at the same time?

[@Heeby-Jeebies]

Your Network Address Translation configuration tells the router how to route and manage IPs. Having both Dynamic NAT and PAT at the same time is kind of like routing your mail two different ways at once, and wouldn't help you if you could. Considering how PAT has all of the functionality of Dynamic NAT and more, you'd be better served by just using that one protocol.
