NAT(第一篇)

NAT的三个实验

【静态NAT】

1、ip nat inside source static 192.168.10.10 209.165.200.225      netmask  255.255.255.0

2、interface s0/0/0

     ip nat inside

3、interface s0/1/0

     ip nat outside 

【动态NAT】

1、ip nat pool pool-name 209.165.200.100 209.165.200.225 netmask 255.255.255.0

2、access-list 1 permit 192.168.10.0 0.0.0.255

3、ip nat inside source list 1 pool pool-name

4、interface s0/0/0

     ip nat inside

5、interface s0/1/0

     ip nat outside 

【过载NAT（PAT）】

I:

1、access-list 1 permit 192.168.10.0 0.0.0.255

2、ip nat inside source list 1 interface s0/1/0 overload

3、interface s0/0/0

     ip nat inside

4、interface s0/1/0

     ip nat outside

II:

1、ip nat pool pool-name 209.165.200.255 209.165.200.225 netmask 255.255.255.0

2、access-list 1 permit 192.168.10.0 0.0.0.255

3、ip nat inside source list 1 pool pool-name overload

4、interface s0/0/0

      ip nat inside

5、interface s0/1/0

      ip nat outside
