I've been trying to use a "Block List" (destination set) with Site and Content Rule for external sites. (spammer/hacker) I desire to block these External sites from accessing all the ISA server services rather than use individual "Packet filter or "Application Filter" entries. Packet filters do not have the flexibility to be applied to more than one site at a time and bandwidth rules do not appear to be able to be applied to achieve this. Routing rules do not appear to be capable of redirecting the External site to some other internet location. Hey that would be grand... redirect/send a spammer/hacker to some internet authority. Thanks Darryl .
