To configure #NAT #Overload (#PAT):

Step 1: If you have not installed Cisco Packet Tracer on Windows, Linux, and macOS before, please refer to the following videos.

Windows ➦ https://www.youtube.com/watch?v=pNLhTixgCXg
Linux / Debian ➦ https://www.youtube.com/watch?v=aMnumAyFxCQ
Linux / Linux Mint ➦ https://www.youtube.com/watch?v=VRmN0pDgLgo
Linux / Ubuntu ➦ https://www.youtube.com/watch?v=rwGuAbiGPdc
macOS High Sierra ➦ https://www.youtube.com/watch?v=cXaqjFukSAI

Step 2: After installing it, add two Cisco Routers and one Cisco Switch to its workspace.

Step 3: Connect the Cisco Routers to each other with a cross cable.

Step 4: Configure the Cisco Switch and PC connections.

Step 5: Configure the 192.168.10.0/24 network for the local network and the 10.0.0.0/24 network for the WAN.

Step 6: Assign IP addresses to the computers from the 192.168.10.0/24 network.

Step 7: Assign the 192.168.10.1 IP address to the Router's GigabitEthernet0/0 interface.

Step 8: Assign IP addresses from the 10.0.0.0/24 network to WAN interfaces of Routers.

Step 9: Before configuring NAT Overload, test the network connection by pinging R1 from the computers.

Step 10: Computers will not be able to ping R1 without configuring PAT (NAT Overload).

Step 11: Open the R0 CLI command prompt to configure NAT Overload.

Step 12: Run the following commands to configure PAT (NAT Overload) on Cisco Router.

Router# conf t
Router(config)# interface gigabitethernet 0/0
Router(config-if)# ip address 192.168.10.1 255.255.255.0
Router(config-if)# ip nat inside
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# interface gigabitethernet 0/1
Router(config-if)# ip address 10.0.0.1 255.255.255.0
Router(config-if)# ip nat outside
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# access-list 1 permit 192.168.10.0 0.0.0.255
Router(config)# ip nat inside source list 1 interface gigabitethernet0/1 overload
Router(config)# end

Step 13: After configuring PAT, ping the R1 again from the computers and examine the results.

Step 14: You can use the following show and debug commands to verify the configuration.

➦ show ip nat translation
➦ show ip nat statistics
➦ clear ip nat statistics
➦ clear ip nat translation *
➦ debug ip nat
