[44net] Linux Gateway Tutorial

I'm trying to decide how to write a "How To" guide for setting up a Linux Gateway for the Wiki. I'm planning on basing it on the excellent guide found here (with Credit): http://marc.storck.lu/blog/2013/08/howto-setup-an-amprnet-gateway-on-linux/ But I'm wondering what level of Linux Administration and IP Networking Expertise I should assume. If I assume zero, it's going to be a looong guide, probably too long. Below is a link to the diagram I was planning to base the guide off of.
