What i am looking for is a feature that basically prevents spoofing by = looking the route for the source and match the incoming interface.=20 A firewall solves the problem but adds alot of administrative overhead = and=20 leaves room for error. Is this feature even possible on FreeBSD? - Sten To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
