We will Explain How to block ping On Your Server and incoming and outcoming ICMP .

(IP Security)

To block all PING traffic to and From a computer you need to create an IPSec policy that will block all ICMP traffic.
Check to see if the computer responds to PING requests by pinging it:



To configure a single computer follow these steps:



Configuring IP Filter Lists and Filter actions
1. Open an MMC window (Start > Run > MMC).



2. Add the IP Security and Policy Management Snap-In.



3. In the Select which computer this policy will manage window select the local computer (or any other policy depending upon Your needs). Click Close then click Ok.



4. Right-click IP Security Policies in the left pane of the MMC console. Select Manage IP Filter Lists and Filter Actions.



5. You do not need to configure a specific IP Filter for ICMP (the protocol used by PING) because such a filter already exists by default - All ICMP Traffic.


However you might want to configure a more specific IP Filter for ICMP. For example, lets say you wish to prevent a Server From answering all PINGS except for specific PINGs sent by a specific computer used by the Help Desk department. In that case you should add a new IP Filter and use Your defined source and Destination IP Addresses, and the ICMP protocol

6. In the Manage IP Filter Lists and Filter actions review Your filters and if all are set, click on the Manage Filter Actions tab. Now we need to add a filter action that will block our designated traffic, so click Add.




7. In the Welcome screen click Next.
8. In the Filter Action Name type Block and click Next.

9. In the Filter Action General Options click Block then click on Next.


10. Back in the Manage IP Filter Lists and Filter actions review Your filters and if all are set, click on the Close button. You can add Filters and Filter Actions at any time.




Next step is to configure the IPSec Policy and to assign it.


Configuring the IPSec Policy

In the same MMC console right-click IP Security Policies on Local Computer and select Create IP Security Policy.




2. In the Welcome screen click Next
3. In the IP Security Policy Name enter a descriptive name, such as "Block PING". Click Next


4. In the Request for Secure Communication window click to clear the Active the Default Response Rule check-box. Click Next




5. In the Completing IP Security Policy Wizard window, click Finish.



6. We now need to add the various IP Filters and Filter Actions to the new IPSec Policy. In the new IPSec Policy window click Add to begin adding the IP Filters and Filter Actions.

7. In the Welcome window click Next.
8. In the Tunnel Endpoint make sure the default setting is selected and click Next.



9. In the Network Type windows select All Network Connections and click Next


10. In the IP Filter List window select "All ICMP Traffic" (or any other IP Filter configured in step #5 at the beginning of this article). If, for some reason, you did not previously configure the right IP Filter, then you can press Add and begin adding it now. When done, click Next.



In the Filter Action window select "Block". Again, if you did not previously configure the right Filter Action, you can now press Add and begin adding it now. When done, click Next.


Notice how the IP Filter has been added.



Again, you can add any combination of IP Filters and Filter Actions you like.
Notice that you cannot change their order like in other full-featured firewalls. Even so, this configuration works perfectly as you will soon discover.
The next phase is to assign the IPSec Policy.

Assigning the IPSec Policy
In the same MMC console, right-click the new IPSec Policy and select Assign.


Done, you can now test the configuration by trying to surf to restricted and unrestricted websites.
