I just washed my dishes while watching this educational multitasking video! This is the minutia answer to the question I never asked because I was too busy, lazy or frightened that I would be labeled a n00b. Thanks Eli for the explainer, force feeding it is the only way I’ll learn.

Thanks mate 200IQ joke success

Still one of the best youtube instructor! thanks Eli!

Honestly theres a single KZreadr that explains anything as well as Eli. Thanks for your videos man you've taught me so much and pulled me out a hole or two too!

I cannot give enough praise to this video. I've been learning about this topic for a few days and I constantly had questions that weren't answered, and gaps in my knowledge. This single video filled in every single hole and answered every single question I had, and some I didn't know I had. Thanks for this amazing resource

Alot of people have questions, on what NAT and Port Forwarding is, and this vid gives alot of good precise answers, to those questions. Thanks again Mr. Eli.👍😄

I like how you refer to the historical origins of things. Helps to understand where we are today. Example: In 1973, everything was peace, love, dove...things changed.

So awesome to see another fellow 💪🏾🤖armitroner lol..wish I still had mine from those wonderfully curious childhood years

thanks, I would appreciate it so much if you always tell us a bit of history like in this video. it was so helpful.

Best explanation of NAT and Port Forwarding I've found on the internet. Great job as always on all your videos Eli!

I love the trips down memory lane...

Great stuff. I listen to your videos on my way to work. That and NPR 😂

Shout out to Eli for still going strong in the game all these decades in. Continued success Eli!

This is great Eli! More please!

Really appreciate the content. Thanks for doing what you do.

Thanks again for another great one Eli. Enjoy your night.

Great lesson. Thanks. Now the remaining question is about DMZ setting what I see as a super port forwarding or all ports open/accessible

One of the best videos on NAT and Port Forwarding. Finally I understood it on a basic level. Your teaching skills are awesome Eli. I am a Programmer and Supporter and hated network issues, but you can explain it in a way, which not f*s my brain up. ^-^

I thought I had heard your voice before... Man, you sound like principal Skinner!

Awesome content Eli. Thanks.

Its good for a refresher.

🙌 the best thanks alto Eli

24:38 that reason is because root is required to run apps on port 80. It is believed to be more secure to run your public facing app without sudo. You can do this by setting up port forwarding from 80 to 8080 on your router.

Thanks for the video. BTW, nice horns :D

The only problem with NAT is that it's easily possible to "Double-NAT", thus causing internet connection issues. Consoles will often tell you that you're using NAT2 or NAT3 during this circumstance. The common culprit is when someone doesn't know to put their ISP's modem into Bridge mode when using their own router.

Nice one.

When explaining the internet cloud, I briefly thought it was an OSPF class.

I appreciate what you are doing in this new series. So in the case of the data going through 2 networks, how does the port number get forwarded through the second router (and the third, etc)? Are more and more port numbers concatenated to each packet? My wireless ISP (Xplornet)puts all of its customers on a 'private IP' 192.168.. so I'm automatically on double NAT considering my own router is in the path right after theirs.

if you own the routers... router 1 port forwards to the external ip of router 2... so router 1 has an external of 205.66.44.2 it's inside address range is 192.168.1.x Router 2's external is 192.168.1.2 and its internal range is 192.168.2.x (different subnet). so port 80 traffic to 205.66.44.2 would be forwarded to router 2 at 192.168.1.2 and router 2 would then forward to the apache server at 192.168.2.10 if your ISP is NATed... that's its own tedious situation...

time stamp 17:41 is when he begins the discussion of NAT btw. If anyone wants to skip to the lesson

SOHO! small office home office, its been a long time since i heard that

Can you please make a lecture on web related stuff like http, https, http status codes, etc? I am watching your videos but haven't come across such lecture Thank you.

What happens if in your network you have a web server, and also another computer that needs to access the outside internet? Would you have to assign your web server a port other than 80?

What if you have both ipv4 and ipv6 enabled and i configure a port for my server with ipv4, but ipv4 isnt available on the wlan so it defaults to a ipv6 connection, will the connection to my server fail? Ive been learning a lot so thank you Eli!

Honestly I don’t think the concept of where the net ID stops and where the host ID begins is confusing. It’s more the math and that we use classless CIDR to configure our networks. Once you repetitively use the equations to figure out what taking and adding a bit does then it becomes very clear.

Newb here, would I set the default gateway as the NAT?

So is it the router ip address that is susceptible to changing randomly according to DHCP, or is it the device ip addresses that are susceptible to changing randomly according to DHCP? Or both

How do I port forward Warcraft 3 so I can host?

Is that a Robotech book?

46:38 that's what I see in our applications code base😂

I wonder how many times an hour Eli uses the word 'literally'?

I love it when people try to hide their Private IPs thinking that some one can hack them if they give that info out. If you had a Static Public IP then yes they can DDOS or Man In the Middle it but Private IPs can not be hacked. Unless your WiFi is open but if your WiFi is open then you have bigger problems.

What? "Private IPs can not be hacked..." Just because they aren't static? Just because network encryption exists? Well hell

@@johnqpublic2718 IP behind a NAT are going to be the same as billions of other private IPs on other LANs so to send a message to a private IP would be sending a message to billions of other computers. This is why Private IP are not routable (or should never be). Only Public IPs are routable. If you could hack all of the routers of the world and make it so they could rout a private IP you would bring down the Internet. So hiding your 192.168.1.n address is just silly.

Also any address in the Class C (192.168.0.0 to 192.168.255.255) Class B (172.16. 0.0 to 172.31. 255.255) Class A (10.0.0.0 to 10.255.255.255) can only ever be behind a NAT.

Yeah it's pretty easy but unfortunately to get the test when you take them You can't pass unless you know cidr notation and have to submit a network. It's easy in practice.

“Some people aren’t very good artists” lol

1st

ill tell ya why! all the damn numbers lol

17:36 for everyone who doesnt want to listen to him ramble for 20 minutes
