Hi All ,

What is the  CGNAT ? . what is the main difference between NAT and CGNAT .

[Seb Rupik · Accepted solution]

Hi there,

NAT can be thought of as a single translation between two networks, typically private <-> public .

CGNAT is a term to cover the NAT implemented by ISP, where two distinct network boundaries are crossed to reach the public internet. private (customer) <-> private (carrier) <-> public (internet)

CGNAT was conceived to mitigate the threat of IPv4 address exhaustion.

cheers,

Seb.
