[R1-acl-ipv4-basic-2000]rule 0 permit source any

[R1-acl-ipv4-basic-2000]quit

[R1]int gi 0/1

[R1-GigabitEthernet0/1]nat outbound 2000

[R1-GigabitEthernet0/1]nat server protocol tcp global 202.1.100.3 80 inside 10.0.0.1 80

[R1-GigabitEthernet0/1]nat server protocol tcp global 202.1.100.3 443 inside 10.0.0.1 443

[R1-GigabitEthernet0/1]quit

[R1]acl basic 2001

[R1-acl-ipv4-basic-2001]rule 0 permit source 192.168.200.0 0.0.0.255

[R1-acl-ipv4-basic-2001]rule 1 deny source any

WAN：

<H3C>sys

[H3C]sysname WAN

[WAN]int gi 0/0

[WAN-GigabitEthernet0/0]description <connect to R1>

[WAN-GigabitEthernet0/0]ip address 202.1.100.1 28

[WAN-GigabitEthernet0/0]quit

[WAN]int gi 0/1

[WAN-GigabitEthernet0/1]ip address 202.103.224.254 24

测试：

内网终端填写IP地址：

外网终端填写IP地址：

内网终端能PING通外网终端：

外网终端无法PING通内网终端：

内网终端打开浏览器，分别使用：https://192.168.200.254和https://202.1.100.3访问SW1的WEB服务

注意：192.168.200.254是内网地址、202.1.100.3是外网地址

1、使用192.168.200.254访问

2、使用外网地址202.1.100.3访问

由上面俩图可以看出，内网终端可以分别使用内网地址和外网地址访问SW1的WEB服务！

至此，双向NAT典型组网配置案例1已完成！
