In the Policies Tab >Right click and add for new Firewall Policy> I given name Internet Site Block


Than Click Rules Tab> in here we can see original firewall rules> Click Add Rule. the "Add Firewall Rule Wizard" will open,Click Next


There are 4 Rule Type in here, Application,Host,Network Service and Blank Rule. Choice Host and click Next


In the Address Type: Choice "DNS Domain"   than write your want to block internet address for example *.facebook.com and click Next.


We will see Trusted Host Rule Complate Screen and DNS names which we add before. We can add more Domain Names, Just click "Add More" button. Click Finish

Now we can see our internet site blok rule in number 8 and name Rule 0.


We should change name for remember it and Click Move Up Button for First Firewall Rule. Than Rigth Click in Action Tab and Select "Block" Therefore we Block this domain name.


When we Click OK Button SEP Manager ask to us for assign this policy now. Click Yes and Choice Group (in the picture i choice test group)

Yes. You can apply different policy for different locations.  However, you can monitor the logs under Monitor> Logs > Network Threat Protection and Attacks/Packets.

Hello NTC
First of all if you write questions in forum you can take fast reply :)
you can create locations. and each locations have got diffrent firewall policy. for your laptop users you can create 2 rules. one of them "in office" rule another is "out of office rule"
therefore the user cannot access www.examplesite.com in company but when he go to home the location will change and sep firewall rule will change automaticly.
Best Regards.

I cannot log on to it..and one thing more, I cannot see any more the green dot on the sep clients..that means they are not connected to the management console…Is there a way to reset the password? And can any one tell what is the solution to this problem..

Thanks and more power

you can monitor it from SEP Manager ;)

Dec 28, 2009 03:54 AM

Is a good article :)
By the way how we can monitor it ? Or pull the report from the firewall or ips where we block the site from SEPM ?

You can also use Intrusion Prevention Signatures. Just create a customized signature. Please see the image below. Inser this line in the content:
rule tcp, dest=(80,8080), msg="Accessing Google Website", content=www.google.com
