Block specific IP address with Sonicwall

Posted on 2011-05-02

I need to completely restrict internet access on my terminal server for all users.  I think the easiest way is to use my SonicWall firewall NSA240.  I assume that it would be done with the IP address or possibly the MAC address of the server using the access rules.  However I'm not to sure about what I'm doing with them, so be pretty direct.

If there's an easier way, of course I would like that!!

    A firewall access rule is probably the fastest. Go to the sonicwall then to Firewall > Access Rules. Click on the LAN to WAN matrix. Add a new rule and confirm it's marked as Deny. Then, choose Service as Any. Choose Source as New Network. Give your new address object a name and select Type as MAC. Place the MAC of the terminal server in the field and click OK. Then, choose Destination as Any. Users Allowed All. Then, click OK. That should do it. If you have challenges with the MAC address object. Go bat to Network > Address Objects and change the object from MAC to Host and enter the IP address of the TS.
