Really great video!! But just one question: Why would S2 entertain request coming from S1 but not from other clients (C1 in this case)?

Thanks!

I ditched Netflix for you !!! Are you a CDN ? I literally love the way you deliver content !

Thank you for the video, Hussein. 🙇🏻‍♂️ I'm a wee confused of the concept terminologies though: how is it different from VPN? Is tunnelling protocol actually the underlying protocol of VPN?

Thanks man

In your opinion, what is the mechanism of teamviewer or anydesk? Thanks

This is very interesting. I use VMware a lot and my concern would be that tunneling might provide a way to negate the benefits of the VM. Is that something someone should worry about?

On the Pros and Cons slide... Isn't it should be STATELESS since you have to reconnect to the server if connection brakes?

Really awesome videos! Is there ever UDP tunneling?

@hnasr

You made me research that haha not sure there is because tunneling require a two way connection.. i suppose you can create a UDP tunnel if you manage it at the application side? But you 100% sure you can tunnel UDP traffic through a TCP tunnel .

I think you are talking about LUCY movie bro in the end.

Any solution ?

So when you connect to VPN from laptop/mobile, essentially what happens is a local port forwarding to that IP address. That actually makes sense. But how do we get a private IP of that VPN network once the connection gets established? In that case, it means we're already connected in that network locally. Then why do we need this local port forwarding? Not needed right? I hope I'll not confusing you.

I talk about VPN here and explain I think answers your questions kzread.info/dash/bejne/oKSi09uLhJqdisY.html

in local port forwarding we are trying to connect to a server1 :3389 but how does the client knows that the tunnel through which it can go is server2:22

@ankuragarwal9712

still the same thing is happening right?.....even server2:22 is also sitting beside a firewall.....so how do client can interact with server2:22 but not server1:3389

A great video, I've learnt a lot, but I have on doubt: 12:40 - this mini server (the entry to the tunnel) is actually an IpSec client? (I'm watching VPN vs Proxy video right now)

Correct! Either an IPSec or SOCKS proxy. Anything that can does the VPNing.

Hey Hussein. You are awesome! I am stuck with a reverse port forwarding tunnel method.. your suggestion would help: I have computers A (dynamic IP), S (Server with Public IP) and C (client with dynamic IP). Trying to access A from C via S. I first created a SSH Key on A. Copied the public key from A to S. Then used the private key to create reverse ssh tunnel from A to S at random port 55000. It connects fine. Then I create a SSH Key on C. Copied the public key from C to S. Then used the private key to SSH to S at port 55000 as follows: SSH -i PRIVKEY -p 55000 Server It says permission denied public Key.. I am unable to get past this.. How to connect from C to A.. I need a programmatic solution.. Can't find a way through this..

Hey thanks for your message. You didn’t specify which port you want to connect on machine A. Am going to assume 80. I think it should be enough to do the reverse tunneling ssh between A and S having S use a the public ip/port 55000 that map to a port 80 on your computer A . Now machine C just connects normally (http) to machine S On port 55000 and that will tunnel requests to your A machine..

Do you know an udp tunneling tool ?

Thanks for the interesting content. I have a question, I red somewhere that in vpn connection first time it uses tcp but inside tunnel it uses udp that is why it is not so slow. But u said it used tcp over tcp or u did not mean vpn connection? By the way it would super helpful if you beside presentation show us real life example or maybe in packet Tracer something like that :D

@hnasr

Elik Elik thanks for the suggestion. As for your comment that VPN tunnels in udp Im not sure if thats true, otherwise you will be losing data like crazy. The slowness is due to extra layer of encryption, multiple hops and packet packaging. Cheers hope that helps

those two dislikes are from hackers i bet
