IPB 203 - The Death of NAT

Network Address Translation (NAT), a foundational element of IPv4, faces critical reassessment as IPv6 deployment shifts the landscape. Ed and Tom evaluate the evolving role of NAT, questioning whether traditional translation models remain necessary when stateful packet inspection offers more robust, transparent security solutions.
