NAT-PT IPv6

Basic NAT-PT configuration

When pinging from inside IPv6 network in the example below with an address to fc00:abcd::172.16.5.66 the NAT-PT will translate the IPv6 packet coming on fa0/1 to a IPv4 packet with destination 172.16.5.66 on fa0/0.

ipv6 nat prefix fc00:abcd::/96
!
interface fastethernet 0/0
description IPv4 only network

ipv6 nat
!
interface fastethernet 0/1
description IPv6 only network
