Hi Tom,

Good Day Sir, Sir is this posible to block the internal IP to block the access to  the internet? we have two separate Domain, Internet Domain and Trasly Domain. the internet domain is our AD and Trasly domain is our ISA Server the use of ISA server is Proxy and firewall and I want to block the IP address, our IP address range 192.168.1.0 - 192.168.1.255. Now I want to block the range of 192.168.1.101 up to 192.168.1.255. 


Thank You

Tomgudi

You don't need to block them, just don't allow them access.

HTH,
Tom

Sir how can I do that?  because they access the internet  just put a IP address and the proxy setting in IE. By the way I am new in this company and I want to revice the proxy and firewall configuration using ISA Server 2004....


Thanks

There are several ways you can do this, the best way is to configure the allow rule to allow only the addresses (would be better if you had user based authentication) you want to allow outbound access through the ISA Firewall.

HTH,
Tom
