Log-input keyword in the ACL will log any packets entering this interface. -----Original Message----- From: 345345 () gmail com [mailto:345345 () gmail com] Sent: July 3, 2005 10:09 AM To: security-basics () securityfocus com Subject: Cisco ACL doubt Hello people, I have the following ACL attached to the external serial (ISP link) of my Cisco 805 Router. access-list 102 remark Egress Filtering ACL access-list 102 permit ip host 100.100.20.34 any access-list 102 permit ip host 100.100.14.102 any log-input access-list 102 deny ip any any log-input And I keep getting lots of log messages from the router (just like the one here!) 2005-07-02 14:13:37 Local5.Info 192.168.0.254 12112: 012109: *Mar 1 17:38:03.975 GMT: %SEC-6-IPACCESSLOGP: list 102 denied tcp 200.227.70.210(0) (Serial0 DLCI 100) -> 100.100.20.53(0), 1 packet As far as I can see, those messages tell that the router has blocked an incoming packet on Interface Serial 0. The Big question is: Why does the router reports this incoming packet related to ACL 102 if this ACL is attached to the Serial 0 OUT??? interface Serial0 ip access-group 102 out Thanks in advance for any help.
