拓扑图如图所示,这是学习NAT,在R5上对内网IP进行静态IP映射的时候遇到的问题,求助各位前辈。 我这里拿了R1做测试,以下是R1的sh run :
R1(config)#do sh run
Building configuration...
Current configuration : 561 bytes
!
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption

end
以下是R5的sh run:
R5(config)#do sh run

Current configuration : 1099 bytes

为什么R1ping 201.10.10.1不通。
然后我对R1做了以下测试:
R1(config)#do sh run
Building configuration...
Current configuration : 610 bytes
!
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption
!
