How does the router count "matched" packets on an ACL?
I have an ACL applied to the Internet facing serial connection of a 7204. I have deny statements in place blocking IP for a couple of class C addresses that hit us with heavy spam. Before placing the ACL we had far more inbound spam messages than are reflected by the counters on the ACL. Does anyone no why the number of matches on the ACL would be so much less? Is a match counted against every packet that comes through the interface and meets the criteria of an ACL statement?
