I doubt the modem is smart enough to single out and only DNS packets (although not impossible of course), in my experience it's probably something like dropping all UDP packets, or all small IP packets, or something more "generic". Apart from an IOS and modem firmware upgrade, can you also crank up the debugging voodoo to see if it happens just before/after/during a PPP or IPoE session flap, or ATM line resync? Cheers, James.
