Created: 12 Sep 2012 | 13 comments


i need to know how to block some web pages with sepm 12.1.

i have ISA server 2004 but some users run the internet explorer/firefox with a user password that have acceses to facebook, (run as).

So i want to use the sempm 12.1 to block that.

I tried some of your articles and have had no luck.

A Quick Note: It is important to have the Application and Device control and Firewall Installed on each Client machine. 

Here are few Articles for the same:

How to Restrict Users to Specific Web Sites by Creating Firewall Rules for Managed Clients
How to block all website and allow only certain websites using Network Threat Protection Firewall rule.

There are few Threads on the same issue as well, I would suggest a quick look into the same.

Check this thread

Thanks In Advance

It is very silly question to ask but at times we tend to look forget to look at small things, is NTP installed on the client?

Some proposals:

Delete IE and firefox; people could use different browsers (Chrome, Safari, Opera ...)

In the Host column, delete all source hosts (origen) because the rule shall apply to all of them anyway ("*.*").

Furthermore, as far as I know the DNS host entry in the Host column doesn't accept wildcards. Thus "*.*" and "*" don't work. However, DNS domain entries do accept wildcards, so take "*" as DNS domain. Change the facebook entry to "*.facebook.*" or "*.facebook*.*".

Good luck!

SEP is not proxy aware, you will need to modify your rules to include the port your traffic is going out through.

Please click the "Mark as solution" link at bottom left on the post that best answers your question. This will benefit admins looking for a solution to the same problem.

Make a simplified test rule with these most important items:

Action Application Host Service Log
Block * All Destination: *.facebook.* * Any Write to traffic log

Apply it to a test group and try if it works.

As another possibility (but not probable), you should check if your clients are in Server Control mode or at least in Mixed control (Clients > Group > Policies > Location.specific Settings > Client User Interface Control Settings). If the clients are in Client control mode, they alone are in charge of firewall rules and the SEPM rules are ignored.
