Explanation of why NAT is not needed in IPv6.
I am pondering how to utilize NAT with IPv6. Looks like you do not even need it anymore. So, what exactly is the idea behind firewall configurations in IPv6 environments?
There is some widespread confusion regarding NAT, so to answer your query of why is NAT not needed in IPV6 - NAT has never been meant to be utilized as a security feature. However, it so occurs that in most cases (not all), when a machine has access to the Internet through NAT only, it is somehow "protected."
