Summarized: Cisco NAT/PAT
Cisco NAT/PAT (Network Address Translation)/(Port Address Translation)
Types of NAT
1. Static NAT
2. Dynamic NAT

Static NAT: Allows you to map an individual IP address from your private network (inside) to a global IP address.
In the image below the laptop with IP 10.1.1.100 is being translated by the router to the global IP address of 222.31.238.15
Copyable Cisco Commands
Router(config)# int f0/0
Router(config-if)# ip nat inside
! Setup Outside Interface (Ex: G1/0)
Router(config)# int g1/0
Router(config-if)# ip nat inside
! Setup Static Translations
ip nat inside source static local-ip global ip
Router(config)# ip nat inside source static 10.1.1.100 222.31.238.15
Router(config)# ip nat inside source static 10.1.1.200 222.31.238.16
