Hi again, Is there a way to restric the use of NAT devices such as a linux gateway, winproxy and wingate on a network? Sorry about my "paranoic" questions, but I am setting up a wireless internet service and I want to be sure that people won't fool me. (or at least won't fool me a lot) Thank you, -- Luiz Felipe Ceglia - Staff TereNet lceglia@terenet.com.br - +55-21-9135-3679
