The fourth experiment nat

Topology design ：

Basic configuration complete ping test

  Default route settings visit isp（pc2）

IP route-static 0.0.0.0 0 12.1.1.2

First use ACL Define private that can be converted ip Address range

[r1]acl 2000

[r1-acl-basic-2000]rule permit source 192.168.0.0 0.0.255.255

[r1]int g0/0/1  The interface of the public network ;acl2000 Private interest in the list ip Address , When transferring out through this interface , Its source ip The address is changed to be public ip

[r1-GigabitEthernet0/0/1]nat outbound 2000

Interface configuration for connecting to the public network

[r1-GigabitEthernet0/0/1]nat static global 12.1.1.3 inside  192.168.1.10

Port mapping ：

[r1-GigabitEthernet0/0/1]nat server protocol  tcp global  current-interface 80 inside  192.168.1.10 80

Warning:The port 80 is well-known port. If you continue it may cause function failure.
