Public IP vs. Private IP and Port Forwarding (Explained by Example)

In this video we will explain how you can author a web application, host it on your laptop then expose it through the internet via port forwarding. We will explain the difference between private ip in Local Area network and Public IP, we will explain how routers have two IP addresses public and private IP.
We will also do a live edit on my router configuration to do a port forwarding of port 8080 to my local laptop and even access that through my phone.

Stay Awesome!

This is what we need! Most sources explain concepts like this with a Networking context and so as developers not only does it not click, but we have no idea what relevance it has to the applications we develop. You explain conceptually and even make a point to show an example with a real world app while omitting "unnecessary" networking terms. And if we wanted to expand to lower level networking aspects we have a better chance with that now as well ..

[@philomath6190]

You explained it better than my college instructor.

[@szilardfineascovasa6144]

This channel is a treasure trove.
Finally getting to understand misc. stuff I just heard thrown around by network or sys-admins.
Thanks, Hussein. And the humor makes everything even better!

[@andresbonelli]

By far the most pristine explanation on this topic. And at last someone with enough balls to show the public IP on a tutorial because when you blur things out on a tutorial it gets confusing, for someone who still doesnt fully understand the topic!!

[@sukiyang3474]

It's like you have the magic powering of explaining things in the most understandable way.

Thank you wonderful session with example. its very helpful for host my website through public

[@ryarod]

There is an online multiplayer game that is now in the hands of the fans to resurrect. In order to do that I need to be able to hold public ip addresses and port my routers.
This video marks the first I've seen in my quest to roll up my sleeves, get to work, and bring Primal Carnage back! I look forward to learning the content this video's title alludes to, among much else.

good day sir, i want to first commend you for the justice you did to the video on port forwarding. neatly explained. thank you very much sir. may God almighty whom i server bless and give you more grace, knowledge and greater wisdom. i was really educated by the simplicity of your teaching. please sir, i need a favour from you, what is the name of the router you used for the above video and how can i get it, i live in Nigeria. once more thanks sir.

شكرا لك

[@antoninperonnet6138]

I think there was only one concept missing: the loopback interface of the router.
On some routers when you request the router's public ip it will not respond: you need a loopback.

[@mostafamohammed4853]

thanks bro

[@boydchongo2556]

wow thanks man

Hussein. Here goes a few courses on college and im not even joking.

[@ramakrishnant7784]

This is awesome. Love it

[@lanncerigs262]

Thank you for the video! It helps me as an aspiring backend engineer :)
Anyway, I have a question. Sorry if it is a dumb question but, why can't you access the application using the public IP even if you are connected to the WiFi? I really appreciate if anyone can answer this question.

[@oscarozorio1005]

That's because that IP it's from the router so it doesn't have the app lets say, the app is running on the machine with the private IP and we stuck at the router who doesn't know where's the app

[@xsorn]

Wow, thank you for explaining it so well.

[@hnasr]

xsorn thanks 🙏 appreciate it ! Have a great day

[@kambalavijay6800]

@@hnasr We have just selected the machine to which request should be routed, we haven't specified on which port the request should be routed to, right? then by default would it go the same port on the forwarded machine?

[@midhundathan4316]

Thanks ❤️

[@jongjong9455]

Can you make a demonstration about trueconf using this concept. Connecting client to the server using internet.. Thanks.

Best tutorial out there

[@f.i4215]

Ive done this and checked port foward checker, it says its closed and it shows me my ;public IP again! any help?

[@shijuvarkeythomas406]

how we can make two different location computer IP in local IP range ?

[@youneskechache1804]

Thanks for the explanation simple and easy to understand, i would to ask a couple of questions if anyone could help me.
Can i use 2 routers for the same home network (same service provider same bill) ?
If yes does that mean the 2 different routers have 2 ip adresses or will it be just 1 ip adress on the 2 routers (the one provided by the network company)?

[@oscarozorio1005]

I guess it'll be only 1 public IP but 2 different IP's for the default gateway IP address

[@ramziallia3437]
