hi,

you can simply accomplish this by removing the condition ALL USERS from your outbound rules and change it with ALL Authenticated Users or by users/groups from your active directory.

HTH,
Tarek

Thanks elmajdal for your reply
all users are Authenticated users as they are a domain users, so changing ALL USERS to all ALL Authenticated Users didn't change any thing,
what happened is that i have just installed ISA Server and i'm using Firewall client instead of SecureNAT and i want all users to go throw the ISA Server and if the user is not Firewall Client the ISA Server should prevent hem form accessing the internet

please advice

Actually i am wondering how your clients are still able to go to the internet !

Rule # 2 will block HTTP . so how ur internal clients are still able to access the internet ?
