Static NAT

In this post I will configure a Static NAT entry on Router1 for the Win7 host. I'll be using the network in the diagram below.



First I remove the NAT configuration from my last post.


router1(config)#no ip nat inside source list NAT pool NAT_POOL overload
Dynamic mapping in use, do you want to delete all entries? [no]: y


Now I configure NAT to map Win7 (10.0.2.1) to 10.0.1.240


router1(config)#ip nat inside source static 10.0.2.1 10.0.1.240


I verify I can reach the internet from the NAT'd host and check the NAT translations


router1(config)#do sh ip nat tran
