I would love to know if you got arch running on this box???
And if you did, if it could be supported on archlinuxarm.
I love my NSA325, but a dual core with two eth's would work well... too well to pass up. And I have a relo in the UK who's visiting soon who could bring me one (as we don't have them in the US).
I know a lot of the core ALARM guys are Brits... What does the magic 8 ball say?
Good info here: http://zyxel.nas-central.org/wiki/Category:NAS540
mucho gracias
