these videos series explain everything network related in crystal clear way that i struggle for years wish i had these videos earlier

[@PracticalNetworking]

Well at least you have them now =). Hope you enjoy the rest of the series to the same degree.

[@eliseriokuan1523]

Thankyou for this series. Am studying for my network+ and this is coming in so handy!

this is a beautiful video! especially the 3 points at the end really add value! thanks a ton! 👍🏽

Thank you so much for these great videos love the effort, I'm sharing your videos with CCNA students for greater spectrum

6:10 if I have another host in my private network that needs static NAT it would have to have it's own public IP address. How is that possible? How can 1 router have 2 or more public IP addresses? Doesn't ISP provide only 1 per router?

[@PracticalNetworking]

A router can have as many IPs as necessary. The fact that your ISP only gives you one is simply a choice by your ISP. Likely you can pay them for more. But from a tech point of view, there is no hard limit to how many IP addresses a single router can have.

[@Gurben92]

You will probably get it this but i can't understand this about NAT: How do packets get to the right host in a network when they source IP is the same (bc of NAT) and the portnumber is also the same because they both do the same thing, like visiting https sites. They both have the same source ip/port right? How will your router know what packet returnes for who?

[@PracticalNetworking]

You're referring to a Dynamic PAT, and I'll explain all of that in a video that is releasing next week =). If you can't wait, I wrote an article about Dynamic PAT here: www.practicalnetworking.net/series/nat/dynamic-pat/

[@Gurben92]

@@PracticalNetworking i ll start with that thank you!

[@ilham5055]

in the next video , could you please explain the different betwen NAT and VPN (IPSec) . iam so confuse what is different. IPSec also had PHASE2 which mean bring local ip (private) . thank you..🙂

[@PracticalNetworking]

The NAT's within a VPN are the same as the NAT's without a VPN. They are orthogonal choices. But you might enjoy this read which touches on both: www.practicalnetworking.net/stand-alone/vpn-overlapping-networks/

That was really useful! Thanks a bunch!

Thank you for your videos, they are amazing! Hey, I have a question. I have a router at work that for some reason was set up with 2 Ips, apparently one for the router 10.x.x.0/25 and one for the NATs routes 10.x.x.128/29. I have been asked what is the problem that I see with this setup… On the one hand I see is that they can be consolidated to 1 single IP under the same subnet. The other issue is the issue of dropping pareces due to this being setup as dynamic, and the connection drops that can occurs due to the dynamically changing Ips. Can you give me your input on what you can see going wrong with this also? I just have to talk about it with my team and I am a bit nervous I don’t want to sound like an idiot. Thank you in advance!

[@kanimozhi6262]

Thank you so much for the perfect explanation. Just to know , when you say , host b tries to communicate host A , at what real time scenario this happens. Can you give some real-time host A and B and at what situation. Sorry if my qn is irrelevant.

[@PracticalNetworking]

The communication is any network traffic sent between the hosts. Host B could be your phone, and Host A could be a Web Site. Or anything like that. More details about hosts here: kzbin.info/www/bejne/mJuQipmXoM-fosU

[@kanimozhi6262]

Thank you so much

[@rotrose7531]

You explain everything so perfect, if you have any full course about networking, please let me know. I would like to pay for the training.

@@PracticalNetworking what does networking course include? is it only fundamentals or full up to advanced level course

[@robinjohn2587]

Thanks for the tutorial

[@PracticalNetworking]

You're welcome =)

[@voytjse]

Good video, but what you are actually showing in your video is PAT since you are changing the port. Also in many firewalls/routers there is nothing called PAT, there is only NAT where you can also change the ports.

[@PracticalNetworking]

Where are you seeing that the Port changed? Each vendor calls their translations something different. I'm using the default terminology from Cisco. Details here: kzbin.info/www/bejne/gXKYZ56gZ5iFhrc

[@voytjse]

@@PracticalNetworking I’m sorry, i didnt see it correctly. The port dosent change 😊

[@PracticalNetworking]

@@voytjse You would be right to say that if the port _did_ change, _then_ it would be a PAT ;) Static PAT video: kzbin.info/www/bejne/h2O7dqJ4erClqdE
