I have PIX 515E with 2 interface, inside, outside, I have PAT from inside - outside and NAT from outside to inside.
I have installed CISCO ASDM, when I am monitoring the status syslog and droped packet rates I found that, ACL drop packet rate is very high, and I have too much syslogs messages for the following errors.
