NAT Overload Configuration on Cisco RouterNAT Overload is probably the most used type of NAT. You can configure NAT overload in two ways, depending on how many public IP addresses you have available. The first case, and one of the most often seen cases is that you have only one public IP address allocated by your ISP. In this case, you map all your inside hosts to the available IP address. The configuration is almost the same as for dynamic NAT, but this time you specify the outside interface instead of a NAT pool. Router(config)#access list 1 permit 192.168.2.0 0.255.255.255 Router(config)#ip nat inside source list 1 interface serial 0/0/0 overload Router(config)#interface FastEthernet 0/2 Router(config-if)#ip nat inside Router(config-if)#interface Serial 0/0/1 Router(config-if)#ip nat outside For more information about NAT Overload, check out NAT Overload (PAT) Configuration in Packet Tracer Comments are closed.
