Client addresses are different but what if multiple clients establish TCP connections from same source port(eg:26650)? A distinction is very necessary. A NAT device will always pick another port number so that 26650 wouldn't be repeated in the NAT translation table.
I got a little confused in router's table. What is hardware address D? Since router cannot know destination server's MAC address, what may that be? Thanks!
If i have more than 1 host the public ip os going to be the same but just changing the ports? Or the clients ports are the same? Or different? Asking that because u used 1024 for every example
I'd argue PAT is layer 4 since a device implementing it must be aware of layer 4 protocols and interact with their headers in order to perform its function. Ports are after all a transport layer concept.
can the NAT have 2 mac addresses?, because you say first it has mac address B internally and then C externally, so i was just wondering if this is really possible..
Now is it possible to find the original IP using the NAT? I’m trying to monitor activity in my Xbox servers, and can’t seem to find a valid IP address, I was thinking that maybe I’m receiving the fake IP like what you’re talking about in the video. I’m new to computers btw, so sorry if I sound like I have no idea what I’m talking about, because I don’t
Cesar Ramirez from what I heard from the video, it sounds like the difference, is that a proxy acts as it’s own client. In other words it’s like a middle man

Happy to see women in tech. Your ability to communicate such complex information so simply is wonderful. Thank you for making these videos.
Laura, good job explaining this in a concise and non confusing manner. Thank You.
Great Video to understand the difference between Proxy and NAT. Thanks for sharing.
Well done Laura! Impressive content, well articulated!
Lovely beautifully explained. Thanks for your work in producing this.
This is fantastic, simple and easy to understand. That you very much for explaining the routing and differences
Well done
5:16 Why do we need to assign ports if NAT offers different addresses inside the local network?

Nice explanation!!! Thumbs up!
It's great explanations. Thanks
Excellent explanation! Worth seeing it.

is the port number generated unique for every host in the subnet? when it sends out an outbound packet to outside host.
Excellent
Great Explanation👌👍

Is mac important for external activities(internet)? What if knows the ip already?
Are the ports from devices unique or differents?

Thanks, best explanation ever.
Thanks Laura
Fantastic Video!
Thank you.! Understood How NAT difference from a PROXY.
Great explanation!
Please let us know difference between PAT , SNAT and DNAT
Hello, I'm trying to get started with wireshark, which book of yours do you recommend first? Thanks
Wireshark 101
Laura Chappell thanks for responding
Great Explanation

G R E A T JOB!
what a Proxy does and PAT does seems pretty similar though

Thanks :)
realy difficult
I just use croxyproxy and dont mind it all)
cute
