You are interested in testing a Many to One NAT configuration. Host A (on the left) should be setup with an IP address of 192.168.101.2 /24 and a default gateway of 192.168.101.1. Host B (on the right) should be setup with an IP address of 192.168.100.2 /24 and a default gateway of 192.168.100.1. The Ethernet interface of Router1 (on the left) should use an IP address of 192.168.101.1 /24 and the Serial interface of Router1 should use an IP address of 192.168.1.1 /24. The Ethernet interface of Router2 (on the right) should use an IP address of 192.168.100.1 /24 and the Serial interface of Router2 should use an IP address of 192.168.1.2 /24. You have a DCE cable connected to Router1. The serial link should have speed of 64K. Configure the routers with RIP; do not advertise the network off of the ethernet 0 interface of Router1. Setup NAT so that all Hosts of off router1’s ethernet 0 interface appears as the IP address of the router1’s serial interface. Make sure that multiple hosts can access the outside world simultaneously.
