This seems to be in line with my observation that no one (to my knowledge) ever reported a deterioration in performance with largish ACLs (or rules, etc.). I simply wonder if going from 700 entries to 7,000 would incur a ten-fold penalty -- whether this is discernable or not depends on the hardware used, obviously. > Since I've been letting the program run automatically to block > IP's I have blocked 3 clients.

Thanks for reporting on your current project status. Sorting and then determining IP ranges makes sense although it is not trivial, as I see it. What language are you using, btw? > Terry Fritts Guy To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
