Cisco ASA message
Posted on 2011-09-30
I have a Cisco ASA-5520 running version 8.4(1). I've been seeing quite a few of these messages in my syslog lately. What has me concerned is that the message says that the packet originates from the inside interface & that the source is 10.37.131.58. I have no such address space on my internal network. 192.168.1.7 is the router facing the Cisco ASA. Can someone enlighten me as to what is going on?
%ASA-4-313005: No matching connection for ICMP error message: icmp src inside:192.168.1.7 dst Outside:10.37.131.58 (type 11, code 0) on inside interface.
Original IP payload: tcp src 10.37.131.58/61004 dst 22.214.171.124/443.
