The very first demand helps site lookup as well second order points out DNS servers to work with.

Establishing NAT for connecting to the web

At this point we now have set up one GNS3 network router to hook up to the net, if you decide to connect even more network routers this router attached to the blur you will find that they aren’t capable speak with websites. The reason is , the actual machine cannot have learned to route the packets generated because of the other routers of GNS3. The best choice because of this is always to do supply NAT on network router connecting toward the blur. Consider the topology below that I will use.

For R2 and R3 to hook up to the online market place origin NAT needs to be designed on R1

For R2 and R3 to hook up to the internet I will be configuring NAT on R1 that is,. the network router connected to the impair.

The software fastethernet 1/0 will be the one c0nnected toward the affect ergo this is the external NAT software.
