How to configure PAT on Cisco router

Asked by At

I have a little problem configuring my Cisco Router1 in Cisco Packet Tracer. I want to ping my PC1 from my PC2, which is in a private network.

I have the following schema:

enter image description here

So, I configured my Router1 as followed:

Router1(config)#access-list 1 permit
Router1(config)#access-list 1 deny any
Router1(config)#ip nat pool nat_pool netmask
Router1(config)#ip nat inside source list 1 pool nat_pool overload
Router1(config)#int gigabitEthernet 0/1 
Router1(config-if)#ip nat insi
Router1(config-if)#ip nat inside 
Router1(config)#int gigabitEthernet 0/0
Router1(config-if)#ip nat outside 

I still cannot ping my PC1 from my private network. Between Router1 and Router2 I configured a static route. I am able to ping from PC2 all the interfaces from Router1 and Router2.

Maybe someone can tell me please the correct steps how to configure my Router1 so that I can ping my PC1 from my private network ( PC2 ).

Thanks in advance.

I answer my own question.

There were a few problems:

  • router2 has not had a 'static' route to my public network
  • I always thought I have to use as my nat pool the public network but I have to use any other public ip addresses.
