1、环境准备：

asav 9.31

vcenter 6.0

2、拓扑

3、配置asa

interface GigabitEthernet0/0
 nameif outside
 security-level 0
 ip address 192.168.1.100 255.255.255.0 

interface GigabitEthernet0/1
 nameif inside
 security-level 100
 no ip address
 ipv6 address fec0::/64 eui-64

route outside 0.0.0.0 0.0.0.0 192.168.1.1 1

object network ipv4_outside_network
 subnet 0.0.0.0 0.0.0.0

object network ipv6_outside_mapped
 subnet 201b::/96

object network ipv4_outside_network
 nat (outside,inside) static ipv6_outside_mapped dns

object network ipv6_inside_network
 subnet fec0::/64
 nat (inside,outside) dynamic interface

4、配置pc

DNS: 201b::df05:505--->201b::/94 加上 223.5.5.5

任意ipv4在转换为ipv6时，是将ipv4转换成十六进制后再加上201b::/94前缀
