| 9.5 |  | Port Address Translation (PAT) |
| 9.5.2 |  | PAT using outside interface addresses |

| Administrators can use the IP address of the outside interface as the PAT address by using the interface option of the global command. This is important for configuring DHCP, which allows for the DHCP retrieved address to be used for PAT. In Figure , source addresses for hosts on network 10.0.0.0 are translated to 192.168.0.2 for outgoing access, and the source port is changed to a unique number greater than 1024.

| Lab Activity e-Lab Activity: PAT Configuration In this activity, the student will configure PAT to allow all internal hosts to share one IP address.
