eNSP實現靜態NAT轉換實驗

eNSP是圖形化網絡仿真平臺,該平臺通過對真實網絡設備的仿真模擬。網絡轉換技術也叫做NAT技術，他的作用就是實現私網IP和公網IP 的轉換來達到網絡的互通

實驗環境：

pc:172.16.1.1/24

R1:g0/0/0 172.16.1.254/24 g0/0/1 192.168.1.254/24

server:192.168.1.1/24

pc和server在不同的網段，現在通過配置靜態NAT實現網絡互通。

網絡配置

pc端

R1端

[R1]int GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0]ip add 172.16.1.254 24
[R1-GigabitEthernet0/0/0]
May 21 2020 14:46:37-08:00 R1 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP 
on the interface GigabitEthernet0/0/0 has entered the UP state. 
[R1-GigabitEthernet0/0/0]int g0/0/1
[R1-GigabitEthernet0/0/1]ip add 192.168.1.254 24
[R1-GigabitEthernet0/0/1]
May 21 2020 14:46:47-08:00 R1 %%01IFNET/4/LINK_STATE(l)[1]:The line protocol IP 
on the interface GigabitEthernet0/0/1 has entered the UP state. 

server端

配置NAT

將192.168.1.20（公網）與172.16.1.1（私網）地址進行綁定

[R1-GigabitEthernet0/0/1]nat static global 192.168.1.20 inside 172.16.1.1

測試

PC>ping 192.168.1.1

Ping 192.168.1.1: 32 data bytes, Press Ctrl_C to break

由此，NAT轉換配置成功！
