asav931 ipv6 配置 nat-pt

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
