Hi It might not be a good idea to assign permission based on IP addresses as most people use dhcp and it changes very often. If ISA is a domain member, create permission based on users. Most likely his ip address is listed in your allow policy. -----Original Message----- From: Javeed Khan [mailto:jkhan@xxxxxxxxxxxxxxxxx] Sent: Saturday, January 07, 2006 10:02 PM To: [ISAserver.org Discussion List] Subject: [isalist] Is it possible to bypass Proxy servers ??
