Looks like the cleanest thing to do to workaround non-cooperative software, as you write. I'ts a pitty to be forced to that, but, at first read it looks well done. I didn't try it because nowadays I only use computers with ar most one eth and one wifi. Just found typos in a comment: # We need to passes to allow interface swappin should be # We need two passes to allow interface swapping Well done. -- Didier _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
