Question

cisco 2811路由器实验:f0/0 ，f0/1各接一台电脑主机并设置好相应的IP及网关，但是互PING就是无法PING通？

配置如下：
Current configuration : 645 bytes
!
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
!
hostname route
!
boot-start-marker
boot-end-marker
!
enable password route
!
no aaa new-model
!
resource policy
!
ip subnet-zero
!
!
ip cef
!

!
interface FastEthernet0/0
ip address 172.16.0.123 255.255.0.0
ip nat outside
duplex auto
speed auto
!
interface FastEthernet0/1
ip address 192.168.3.1 255.255.255.0
ip nat inside
duplex auto
speed auto

ip classless

no ip http server

!
control-plane

!
line con 0
line aux 0
line vty 0 4

end
模拟器上两台主机都可以ping通，实机就是无法ping通？哪位好心人告诉我一下！谢谢

Answer 1

你先去掉接口下的ip nat inside 和 ip nat outside， 然后确保电脑的防火墙都关闭。

Answer 2

看系统防火墙开了没 ，检查 IP 配置好 就没问题了
