I mean, sure, asking for 45 USD for a CD with the source is technically complying with the GPL -- but it does seem a bit strange in this day and age. Not to mention that for the source code to be useful, one would hope one could build a working routerOS image from it -- and it doesn't appear that the CD will enable a user to build a running image -- and therefore not facilitate changing the product.
But apart from that, my first thought was -- can this thing run BSD -- because pf is quite a bit friendlier than iptables (even if the latter has gotten a lot better lately).
Does anyone know if there are any recommended alternatives to soekris for running a bsd switch/router (preferably running at ~gigabit speeds) ?
