Harold, Fully agree with you, it's for an unusual telco regulatory requirement in the middle east, and to be fair more of a 'tick in the box exercise'. I was only looking at this as a very tactical option to provide more time to plan out a dual-stack deployment, however, everything is pointing to scrapping this and going dual-stack day 1. I then became curious as to why the config wasn't working, more for my own curiosity but guess some things aren't worth spending too much time on. Many thanks and all the best, Andy

Has anybody configures dynamic/hide IPv4 to IPv6? I have a requirement for IPv4 only hosts to connect to IPv6 Internet sites, I originally tried to lab NAT-PT with DNS ALG. <IPv4 only host> --- <Cisco Router with NAT-PT> ---- IPv6 Internet NAT-PT DNS is ALG configured IPv6 NAT service for DNS IPv4 NAT works fine IPv6 from the router works fine From an IPv4 Linux host, the IPv4 NAT isn't working. Lab config: Inside interface: interface GigabitEthernet0/1 ip address 10.0.0.5 255.255.255.252 ip nat inside ip nat enable ip virtual-reassembly in duplex full speed auto media-type rj45 ipv6 nat ! Outside Interface: interface GigabitEthernet0/2 ip address dhcp ip nat outside ip nat enable ip virtual-reassembly in duplex full speed auto media-type rj45 ipv6 address <IPv6 address>/64 ipv6 enable ipv6 nat ! ipv6 route ::/0 <IPv6 G/W> ipv6 nat v4v6 source list 75 pool v6pool ipv6 nat v4v6 pool v6pool <IPv6 start address> <IPv6 end address> prefix-length 64 ipv6 nat v6v4 source<IPv6 address> <External IPv4 address> ipv6 nat prefix<IPv6 address>/96 This is a stop gap for an immediate requirement until we can get a proper Dual-Stack design and implementation in place. Any advice would be greatly appreciated.
