[44net] Linux tunnel gateway configuration?

Does anyone have a step-by-step set of instructions for configuring a Linux host as a tunnel subnet gateway for AMPRNet?

I'd like to have a proven list of all the commands that have to be entered to set one up.

I think it would be very helpful and I don't have such a document in my archives.

Thank you! - Brian
