Recently i have installed ISA Server a Windows 2000 Server, which is connected to network.
After installation i found that all traffics from ISA Server to and out was blocked by default access rule, so i created the following access rules under firewall policy.
Priority : 1 Name : Restricted Internet Access Action: Deny Protocol: All outbound Traffic From: Internal To: External Except: Allowed Domains Rules Applies: Restricted Users
Priority: 3 Name: Internal-External Action: Allow Protocol: All Outbound Traffic From: Internal, Localhost To: External Rule Applies: All Users
Priority: 4 Name: Global Action: Allow Protocol: All Outbound Traffic From: Internal, Localhost To: Internal, Localhost Rule Applies: All Users
## Default Rule ##
Priority: Last Name: Default Rule Action: Deny Protocol: All Traffic From : All Networks (and Localhost) To: All Networks (and LocalHost) Rule Applies: All Users
To the above, i have enabled caching on ISA Server and not applied any network template.
