Does that mean you could reproduce the problem just with bce0 and no jail+vnets at all just with IPv4, IPv6, and ipfw on the main host? If you cannot, would starting a vnet-jail (without the bridge and connecting the epair), just starting a jail in persist mode, make a difference; or would strating a jail and applying the ipfw rules therein start the problem? > Does anyone have any ideas? I'm out of ideas. y best guess is to move the thread to freebsd-ipfw (Cc: and Reply-To: set) and see if people pick it up there some more and also finding the minimalistic case to reproduce. /bz
