Routing example
This example illustrates a typical network architecture of routers and default gateways in several networks. The following points are illustrated in Figure 3
- Company XYZ has a single network using the private class C address of 192.168.1.0.
- The router is performing NAT to translate the address of Host C to a legitimate address on the external network when Host C uses the Internet.
- The network is not subnetted.
- Company ABC uses the same private class C network, but has subnetted it to provide two networks, one at each site.
- The router is performing NAT to translate the addresses of hosts from both private networks to addresses on the external network when the hosts access the Internet.
