DMZ PAcket Filtering

blueorder
I have a mail/web server and my wireless network on a DMZ.  I have packet rules setup for the server and Xbox on the wireless for access.

Code:

DMZ_Network_ {Server Services}    Any Allow
DMZ_Network_ {Xbox Live Services} Any Allow


Now, I want to add a "catch all" rule to drop any traffic from the DMZ network to the Internal network (even those allowed to go out to the Externa Interface).  Would I put that before or after the two previous rules?

And, would the rule look like: 

 Code:

DMZ_Network_ Any Internal_Network_ Drop


Thanks

    It depends.

    If you put the block rule first, then you won't get {Server Services} and {Xbox Live Services} through from the DMZ to the Internal network.

    If you put the drop rule after the two service allow rules, then those two service groups will get through from the DMZ to the Internal net.
