配置静态NAT遇到的问题

sokillwhat

具体配置如下：



Router1 Serial0 : 10.1.1.1/24
Router1 Ethernet0 : 192.168.1.1/24

Router2 Serial0: 10.1.1.2/24

Router3 Ethernet0: 192.168.1.2/24

三个路由器已经设置RIP/Clock Rate，并且三个路由器可以任意PING的通：）

这个实验的目的是在Router1上设置了Router2被NAT过的IP，从而从Router2上Telnet到Router3时，在Router3上面看到的是被NAT过的Router2的IP：）

具体在ROUTER1上的NAT设置：

R1#show ip nat translations
Pro Inside global Inside local Outside local Outside global
--- 172.172.172.172 10.1.1.2 --- ---

R1#show ip nat statistics
Total active translations: 5 (0 static, 5 dynamic; 5 extended)
Outside interfaces: Ethernet0
Inside interfaces: Serial0
Hits: 5 Misses: 5
Expired translations: 5
Dynamic mappings:
-- Inside Source
Access list + 0interface refcount 0
******************************


可是无论是从Router2上Telnet 到Router3上，还是从Router3上Telnet到Router2上，都显示：“Telnet not available”,求专家们帮忙～！～！

3台路由器都是CISCO的2501型

R3添加：

ip route 172.172.172.172 0.0.0.0 192.168.1.1
语法有错误的话自己改。

ssffzz1

哦。也许是ip route 172.172.172.172 255.255.255.255 192.168.1.1
忘记了。

添加了，还是不好用啊

你用的模拟器，还是真机。

模拟机，用的是Boson的。。。。

是不是只要有我的那些设置，应该telnet 不成问题吧？

ssffzz1

组要不要用模拟器来做。这个只适合于你熟悉命令行。

已经验证，上述配置无问题。R3可以通过172.172.172.172来访问R2.
