H3C NAT配置实验
H3C NAT配置实验
实验拓扑
实验需求
- 按照图示配置 IP 地址
- 私网 A 通过 R1 接入到互联网,私网 B 通过 R3 接入到互联网
- 私网 A 内部存在 Vlan10 和 Vlan20,通过 R1 上单臂路由访问外部网络
- 私网 A 通过 NAPT 使 Vlan10 和 Vlan20 都能够使用 R1 的公网地址访问互联网
- 私网 B 通过在 R3 上配置 EASY IP 访问互联网
- 私网 A 配置 NAT SERVER 把 FTPA 的 FTP 服务发布到公网,使 PCB 可以访问
实验步骤

port link-mode bridge
port access vlan 20
#
interface GigabitEthernet1/0/3
port link-mode bridge
port link-type trunk
undo port trunk permit vlan 1

nat outbound 2000 address-group 1
私网B 配置EASY IP
#
acl basic 2000
rule 0 permit source 192.168.1.0 0.0.0.255
#
interface GigabitEthernet0/0
nat outbound 2000
私网A 配置NAT SERVER
#
interface GigabitEthernet0/1
nat server protocol tcp global 100.1.1.1 20 21 inside 192.168.1.1 20 21
