Is anyone else using the AT&T (well, now comcast) @home service from a linux box, and occasionally (actually, fairly frequently in my case) getting high (say, 50%) packet loss ? If you do, I might have a workaround. I'm guessing that windows users are not affected by this AT&T broadband bug, due to subtle differences in the behaviour of their ARP cache. When I finally understood what happens and how to fix the issue, I thought it was fairly funny :) I still have no idea what this network behaviour is supposed to accomplish though.
