Caveat: You can't accomplish this with the busybox-as-'ip'-replacement used by default on the FR, you need the complete iproute2 version. (busybox version doesn't support 'table' or 'rule') I've not noticed if it's made it into a feed yet, I always install http://newkirk.us/om/iproute2_2.6.26_armv4t.ipk which I built a few months ago and keep at the 'FR stuff' link in my sig. j > On Tue, Jan 13, 2009 at 4:34 PM, Al Johnson > <[email protected]> wrote: >> On Tuesday 13 January 2009, Leonti Bielski wrote: >>> Hello! >>> Is it possible to use multiple internet connections on Freerunner at >>> the same time? >> >> There are several possible ways depending on circumstances.
