Cisco路由器上配置网络地址转换(NAT,Network Address Translation)通常用于隐藏内部网络的IP地址,以便对外提供服务或保护网络安全。以下是使用Cisco IOS模拟器进行基本NAT配置的一些常见命令:
1. **启用NAT**:
```
enable
configure terminal
nat
```
2. **全局NAT配置**:
- 配置PAT(端口地址转换):
```
ip nat inside source static [protocol] [inside-source-ip] [outside-source-port] [outside-destination-ip] [outside-destination-port]
```
- 或者配置静态NAT (SNAT):
```
ip nat inside source list [list-name] [interface] [translated-address]
```
3. **NAT池配置**:
```
ip nat pool [pool-name] [start-ip] [end-ip] [netmask] [default-gateway] [leasetime]
```
4. **NAT映射规则(动态或 PAT)**:
```
ip nat outside
translate address [inside-source-ip] [outside-source-ip]
map [dynamic | protocol [port]]
```
5. **配置NAT访问控制列表(ACL)**:
```
access-list [access-list-name] permit/deny [source-address(es)] [destination-port]
ip nat inside source list [access-list-name] [interface] [translated-address]
```
6. **查看当前NAT状态**:
```
show ip nat statistics
show ip nat translations
```
请注意,实际配置可能会因网络环境和需求的不同而有所变化。在进行任何配置之前,建议参考具体的路由器型号文档,并了解你的网络拓扑。
