It works! It works! Thank you!

No problem. It's very chatty on startup, but that's DEBUG builds for =
you. I'm not
complaining.

I could do that!

Cool. =46rom where do I clone?

Its going to be a combination build-box (occasionally) and =
firewall/gateway (permanently on).
I'm retiring an old, power-hungry PC and I want a gateway that can do =
double-duty as a background
buildibox. "Console" here doesn't imply graphics; just enough to do =
basic administration.

I chose it because of its capabilities :-) the price is acceptable.

I also have RPIs, WandBoards and so on, but these aren't much good for =
building. Pretty, though!

Naah. It will be routing DSL broadband for a living.

Aah, OK. I have zero knowledge of that myself. :-(
