Hi Phil.

As Loris explained some days ago on the mailing list 
(http://www.winpcap.org/pipermail/winpcap-users/2005-July/000202.html) we 
are definitely planning to add such feature, but it won't be available in 
the upcoming WinPcap 3.1. The idea is putting some ACLs on the npf devices 
to selectively allow/deny tx and rx through a control panel applet (or 
something similar).

Have a nice day
