Hi All,   I have one question regarding IP acces-list logging. I have block IP access of one server with the following command. deny ip host x.x.x.x any log (where x.x.x.x is the server ip).   Now if somebody trying to ssh to the server SSH is denied but the logg is showing that the access list denied ICMP traffic to reach the server(denie icmp x.x.x.x -> y.y.y.y (3/3))   y.y.y.y is the host from where ssh connection is generated. Acl is applied on server vlan interface I failed to understand the reason behind the this. Could somebody help me please.   Regards,   Arijit ... View more
