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 -.-

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.

@JeremysITLab 3 жыл бұрын

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.

Hello jeremy. I have a question that has been created from this lecture. Lets take as an example the diagram that you use to demonstrate NAT. In 192.168.0.167 we run a FTP server and on 192.168.0.168 we run a SSH server. Someone from the Internet tries to access one of those servers with 203.0.113.1:22/21. How the router can know where to translate the traffic to? Is there a specific concept that is used for this purpose? Thanks in advance.

@murtuzahussain2236 3 жыл бұрын

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?

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.

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.

" Packets denied by the ACL will not be translated ", so in this case the device will not be able to communicate with the other device, and if so isn't it the same as dropping the packet ?

In this case yes the ISP's device will drop it. But don't confuse another device dropping a packet with 'packets denied by the ACL will be dropped', because that's not what's happening.

Sir, In Quiz 5, when ACL denies a subnet and packets from that subnet won't be neither discarded nor translated what would the router do with those packets??? If the packets couldn't be forwarded isn't it better that the packet be dropped??

The router will forward the packet. It doesn't know that the other router it's connected to (the Internet router) will drop the packet.
