A wildcard of 0.0.0.0 means that the entire IP address must be examined
A wildcard of 255.255.255.255 means that the entire IP address will not be examined


Likewise, if you want to filter all hosts in a subnet that uses subnet mask 255.255.252.0, the wildcard mask 0.0.3.255 matches the network and subnet bits.

Get it?
So if you want to filter out all hosts on 255.255.255.0 subnet, the wildcard mask is 0.0.0.255.
 
Thanks celticfan, that made some sense.... im trying to figure the applying mechanisms like to put it on which interface and in/out direction...

Also Hi EP and people. I found this place again while looking through a oooollllllldddd backup. I have filled over 10TB and was looking at my collection of antiques. Any bids on the 500Mhz Win 95 fix?
Any of the SP crew still out there?
