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
