Thanx Jim.
I'm trying to develope some addtional features on ISA, for example
Auto-Blocking Spammers, Intruders and Worm attacks on Web Proxy...
This means that I have to create a Packet Filter for each Intruder IP on
each External IP Address of each Server of the Array...
Can this affect server performance, as each packet has to be checked with
all the filter conditions before being allowed to pass?
Thanks Again
Max
