CHAPTER 23. Firewall NAT 

242

 

© SAMSUNG Electronics Co., Ltd. 

 
The PAT configuration shown in Figure 23.5 includes:   

 

Private network address: 10.1.1.1-10.1.1.3   

− 

PAT address: 50.1.1.5 

 

Method: 1-Specifying NAT address with the policy 
command  

To configure this method of PAT, add the policy with the source IP address 
range, then specify the nat-ip

 

address in the 

policy

 command.   

 

Router/configure# firewall corp 
Router/configure/firewall corp# policy 2 out address 
10.1.1.1 10.1.1.3  
any any nat-ip 50.1.1.5 
Router/configure/firewall corp/policy 2 out# exit 2 
Router/configure# 

 

Method: 2-Attaching nat pool to the policy   

To configure the second type of NAT, create a NAT pool with type pat

 

and 

specify the IP address. Then add the policy with the source IP address range. 
Finally, attach the NAT pool to the policy.
