Static PAT - Network Address Translation

Static PAT (Port Address Translation) is a 1:1 translation between one [IP address & Port] and another [IP address & Port]. A Static PAT would be used anytime you mean for a specific port to be translated through a NAT device.
In this video we show you the packet flow through a Static PAT, showing you the packet before and after translation -- in BOTH directions (inbound and outbound).
This is a look at Static PAT from a Vendor Neutral perspective. The concepts in this video will apply to any Static NAT translation, on any platform, from any vendor.

excellent explanation in the simplest way to describe. if still somebody cannot understand then i guess nobody can

[@PracticalNetworking]

Thank you for the kind words =). Dynamic PAT / NAT videos releasing this week, by the way =)

[@paritoshd9776]

I am not sure why this video does not have millions of views. It is EXTREMELY helpful for a university student, a working professional, a curious mind you name it!! Have saved this NAT playlist.

[@PracticalNetworking]

Glad you enjoyed it, Paritosh =). If you're willing... Do you mind sharing this video on Linked In, Reddit, Twitter, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ . It would help me get to that million views ;)

[@paritoshd9776]

@@PracticalNetworking Sure, will do. Glad to spread knowledge!

@@paritoshd9776 Thank you kindly =)

It does not show if there are two privates, how does router determine the rule? When i purchase a router i didnt set this up, but how?

[@douglaslawrie3449]

I’m a control systems engineer addressing some gaps in my networking knowledge and these videos have been so so helpful. Thank you. This playlist on NAT has answered a question that has been bugging me for a while. “How do two hosts with the same IP in different local networks establish a connection?”

[@PracticalNetworking]

Awesome, Douglas. Glad these have helped clarify concepts =). Have you seen the Networking Fundamentals series? THat's another great one for cross discipline training: www.practicalnetworking.net/index/networking-fundamentals-how-data-moves-through-the-internet/

[@ciscornBIG]

Honestly, reading your comment makes me feel better about myself and not in a put downy way. You have such an impressive title and didn't know this. I have no title and knew this.

[@FoysalChowdhuryGoni]

Similar to IP port forward, excellent video, Thank you very much

[@PracticalNetworking]

You're very welcome =)

[@afsala.a.6598]

Thank you so much for the presentation . One thing - 8:16 “we could create a third static NAT entry...” actually it’s *PAT entry 😊

[@PracticalNetworking]

Ha! good catch! THat's been up for a while and I don't think anyone has pointed it out. Thank you =). It's probably too late to fix though. But either way thanks for bringing it to my attention.

[@cuspajzz]

Great video 😀

[@PracticalNetworking]

Glad you liked it !

[@afsala.a.6598]

Can we add two mail servers on this inside network and can both use same public IP address?

[@PracticalNetworking]

Same public IP? Yes. Same Public IP & Port? No =/ They would have to be unique ports.

[@IliyaDamyanov]

Very good video.

[@warisgeorge4317]

Thanks

[@PracticalNetworking]

You're welcome, Waris.

[@a13519]

How doyou determine the portto translate? Who makes decisionz?

[@androiddoctor4897]

Is this static pat and port forwarding both are same ?

[@PracticalNetworking]

Yes, for the most part

[@amitpatil1900]

What if two web servers hosting on port 443 but both the servers have different private ip address so in this scenario static PAT will work?

[@PracticalNetworking]

Yes... but you'll need to use a different port number on the shared public IP.

[@unathorizdwatermelon]

In my book it refers to DNAT as destination NAT not dynamic NAT. This is also what I'm seeing on google. Are these terms interchangeable?

[@inderdeepsingh4076]

Thank you!!
