Greetings Sir, PAT ke regarding ek chota sa doubt tha.
We all know that Layer 4 pe Source and Dest ports add hote hai, right.
And in PAT, it adds a port no with the Public IP, right.
So agar aisa hai to phir 2-2 source and destination port ho jayenge na, ek PAT ka add kiya hua r dusra Transport layer pe add kiya hua. I am very confused.

[@PMNetworking]

PAT ek apna port number lgta hai reply identify krne ke liye, like http ko ek request bheja hai uske liye port number 1 use kr liya av jab reply me destination port 1 rahegi to usse phirse translate kr sake

[@maxnoob1982]

can we say GRE also use for connect 2 diffrent branches ?? over isp

[@PMNetworking]

Yes

[@networksecurity778]

Sir why don't you create a complete VPN playlist ???????

[@PMNetworking]

Sure, I will

[@shewittesfay4039]

pleas clarify and difference and similarity CSMA/CD and CSMA/CA

[@PMNetworking]

CSMA/CD is works after collision to stop next collision and CSMA/CA is work before collision to avoid collision.

[@PMNetworking]

CSMA/CD is used in a wired network and CSMA/CA is ised in wireless network

[@MariaGomez-lg2ug]

“I’m not clear on something. Why don’t you mention the public IP that was translated at the ISP and not at the router? I understand NAT perfectly, but it’s not clear to me if NAT operates with the public IP from the local outside interface because that is something provided by the ISP’s router. How can a router that manages the LAN know the public IP? This part is confusing to me.”__??????????????????

[@PMNetworking]

You will purchase the public ip for wan interface
