  Can't be done.  Cygwin runs entirely in user mode; it has no ability to
run applications in kernel mode or to act as a windoze device/filter driver.

  Having said that, you might be able to half bodge together a leaky and
semifunctional one using the ip receive hooks, but it'd be shot through with
holes.

  In short:  use a windoze firewall.


    cheers,
