Let's look at how we will achieve this. Previously, we showed how to configure routing to allow data to flow between the two subnets by using a gateway (we defined the two interfaces “indium” and “tin” to accomplish this). Figure 13.1 shows the network at the stage where we had successfully connected all the systems together and had implemented any required routes and gateways.
Figure 13.1. The existing network—a reminder.
We will now use “xenon” to perform a similar function, but this time to the external network. Once this has been set up, all the other machines will be able to access the external network using this route. This is ...
