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, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
