SSH Tunneling - Local & Remote Port Forwarding (by Example)

[@antonimihailov8046]

It is really, really great that there are still tech channels which actually share tech knowledge and don't just publish videos, such as "top languages to learn in 2025". I really hope you keep up with this great videos and don't become a slave to the algorithm.

Man tell me about it, I made a video last year ranting about videos claiming Top programming languages in 2020 kzbin.info/www/bejne/f5uym5x8acSWh8U

The only guy on the internet that explains SSH port forwarding and remote port forwarding properly.

[@ThanhTran-wf2jf]

This is BY FAR the best explanation of local & remote port forwarding that I have seen anywhere. It makes it very clear exactly who is requesting what from where at each point in the request, and the separation of resources is most helpful ; most other explanations will have the requested resource and the ssh server be on the same host, not making it clear that the requested resource can actually be running on a different host. Huge thanks to you for sharing such a great video with us!

[@DavidChandra]

Agree with you. This is the best tutorial video.

[@Abinashdash17]

Completely agreed.

[@maxteer2800]

This covered in 7 minutes (only needed local) what I've been trying to understand for a couple weeks... I normally don't "research" on youtube, but your practical example was great. Thanks so much!

[@callistachang8358]

Hey there - I stumbled upon your video when I was looking up reverse proxies and I just wanted to say that you're such an excellent explainer! I see from your profile that you update frequently and consistently. Thank you for doing what you do, I'd definitely recommend this site to my friends when you cover topics they like!

[@hnasr]

Thank you soo much cal for taking the time to write this 🙏 very happy you like the content ! I try to upload frequently and i talk about topics that i am interested on

Your teaching clip was the best of any video I have ever seen and full understandable and simple, thanks 👍

[@rvoros]

Clear, to the point, no BS explanation. Well done!

[@x7331x]

I have read so many articles and I was really struggling understand what happens behind the scenes. Brilliant explanation and visuals, thanks you!

[@iamjirho]

Having difficulty to wrapped this concept around my head and you absolutely nailed the explanation!

[@nabeeltahir6013]

this was such a clear and helpful explanation. I have been struggling with this concept for a while but you broke it down perfectly. Thank you for making it so easy to understand

[@abdalla_zaki]

Man, you are the guru of back-end engineering

[@LukePammant]

Awesome explaination! I read (*skimmed*) 5 articles on local vs remote port forwarding and didn't grok it until I saw your visuals. Thanks for this!

[@Abinashdash17]

super super helpful. This single video cleared all the confusion I had about local and remote port forwarding. Thanks man!!!

[@АртемВовченко-у6е]

Wow, such an amazing explanation! Thank you a lot! Finally, I have understood ssh port forwarding:)

[@gangstaberry2496]

This is the best explanation I have found so far... Thank you so much ^^

[@noahwilliams8918]

Thank you for making this video Hussein! I've been trying to wrap my head around remote port forwarding for the longest damn time. I live in an area with shared wifi and I've been looking forever for a way to circumvent the stupid firewall so I can get some of those sweet sweet LetsEncrypt certs for my Raspberry Pi's! I've watched so many videos on this and not found a single one that isn't either a) using PuTTY on Windows, which is useless since it doesn't show which command line args to use or b) a purely conceptual explanation with no examples or instructions!

[@hnasr]

Noah Williams thanks Noah! Glad I could help. This concept is very complex believe me I go back to my videos all the time to remember how I did things. So i try to put the commands .. which reminds me must make sure i put it on this YT description

[@hashithbandara111]

i can understand this lesson very well because of terminal practice of you

[@yousofebneddin7430]

this is exactly what I needed. Thanks.

[@demandelz]

Thank you sir. This was exactly what I needed. I don't know why on Earth I had so much trouble building a remote ssh tunnel, but I did and it was only after viewing your video that I was able to get everything working solidly. Once again thank you for the clear explanation.

[@mrdr9534]

Thanks for taking the time and effort of making this great video and sharing Your knowledge !! :) Best regards

[@gillfromamritsar]

Great Video, I am using this technique to create tunnel from my local to server, additionally, I am using "-fNL" params. The -f option tells the ssh command to run in the background and -N not to execute a remote command.

[@vladislavkaras491]

Really thanks for the explanation! It was great!

[@jorgensenabrahamson6479]

I don't have a public dynamic ip. My ISP shares my IP with others, it means I am behind a NAT. I tried to use remote port forwarding to see my DVR and NAS, but the problem is that I can not publish ports in my router. In the example described in the video that tunne it's not needed, you could configure the router to forward the ports of that internal resource with out needing a 3rd party server. However, I am able to see a port of an external database server and see it as a local resource.

[@hnasr]

Ill make a video on this topic you can use ngrok.io

[@jorgensenabrahamson6479]

@@hnasr I evaluated that solution but it's limited :( thanks for your really quick answer

[@hnasr]

Yes it is very limited and terminates your connection.. best way is to purchase a tiny vm from linod

[@jorgensenabrahamson6479]

@@hnasr what could I do with that? I have my own server in cloud at cost, that's where I tryied to do the tunneling solution , what do you suggest to install to achive my purpose?

[@TyphoonBeard]

Thank you very much for the great explanation! I have been wondering, if it is possible to achieve the same thing (hosting a web server) if my router gets a private IP from the ISP... I just cannot find a straight forward tutorial or explanation, how this thing may work. In your use case, if I understood correctly, you use the public IP of the router, but mine is private as it doesn't match with the IP what I see from "outside" ip tracking webpages, and the port forwarding simply doesn't work.

[@marcelo_luz]

Im also interesting to know about it, since i dont have a static IP and my ISP blocked the majority of the ports.

[@TyphoonBeard]

Marcelo, the only option I found is, to use a service like ngrok or other alternatives with similar functionality. Basically it is a service, which creates a channel between your server and an external hosting service. The mentioned one has some free possibilities, so you can try it out just by creating a free account. For a paid plan you can also create your own domain if you like. I hope this helps a little. Cheers!

[@marcelo_luz]

@@TyphoonBeard thank Florián, I'm here breaking my head.. at the moment I'm trying ngrok without success. Actually I just wanna turn on my computer over the lan (Wake on LAN remotely - WOL/WOW).

[@securiosityy]

This is a really good explanation of SSH tunneling and port forwarding! Unfortunately one can only appreciate the accuracy after seeing so many very confusing and even incorrect explanations on KZbin. It's important to get the terms right and use proper examples (e.g. "local" or "remote" from which machine's perspective) and where the connection is initiated etc. Too often something like "SSH -R 1080:localhost:1080" is used which is the worst way, as students can't see which machine each component is referring to and what's actually happening here. So, thank you for going the extra mile with the diagrams and being careful with how you use the terminology.

How to set up Remove Port Forwarding if your ISP also blocks SSH access remotely?

[@hnasr]

Interested to know how do they block it.. wonder if it is on the port.. can you change port 22 and run openssh on a custom pprt?

[@TanuKart]

@@hnasr Looks like they block all ports for incoming traffic. Even ports such as 80, 21,22, 23. I've tried them all

[@supa1954]

So i setup Pi-Hole on my Raspberry pi, with Pi-Vpn to install openvpn alongside my Pi-hole then i logged into my router made it a static ip, now im trying to setup port forwarding to the raspberry pi on port 1194 that openvpn uses What confuses me is my router asks for a internal host ip which i set to my Raspberry Pi's ip, and external host ip, i ended up leaving the external host ip blank, im trying to access my Pi-Hole Adserver while im at work does that require me to put a ip for the external host? I made my internal port, and external port 1194

[@nixexd]

Hi Mr. Hussein. I like to ask some Question. How to fix Connection refused when run the ssh command and fix bad local forwarding specification 'ip adress'?

[@Eagle-md6ku]

Why did you have to create a name for your machine's IP on the public DNS server? (The noIP website @ 8:33) Is this a required step or can I just use the SSH server's IP?

[@hnasr]

No reason you may use the public IP address just wanted an easy way to write it down

[@pdamiano]

amazin video, TY !!!!

[@tushargoel5049]

Hi Hussein Even if we do not use ssh command to access the remote server, we can still access it by making a TCP req on public ssh server on port 22, right?

i'm trying to forward something from my NAS on port 8080 and i'm doing ssh -R 8080:localhost:8080 user@ip and i can't seem to connect to it from ym vps when i connect to the VPS IP address. do i have the wrong IP? if i do this on my PC, i can forward anything on the PC to my VPS as long as i'm connected to wireguard and if that user connects to my internal wireguard IP (10.190.x.x)

[@palaniappanrm6277]

This was an eye opener for me. This is so powerful actually. But the public SSH servers available will actually block these stuffs right?

[@hnasr]

Glad its helpful! correct its rare to find a public ssh server that has port 22 open but very easy to spin one up with a $5 droplet from cloudflair even cheaper
