The video demonstrates a method to interface IPv6 to IPv4 network using NAT-PT on Cisco router. We will cover the basic 1-to-1 static NAT, dynamic NAT, and PAT primarily translating IPv6 source IP to IPv4. We will then look at DNS ALG feature that helps rectifying an embedded IP as DNS reply crosses IPv4-IPv6 boundary, while analysing it by Wireshark. We will configure IPv4 Mapped NAT feature to automate destination NAT process by mapping the entire IPv4 address space to IPv6 /96 subnet. The lab finishes with modification of the NAT global timeout values.
