Can someone explain why I might be getting the following syslog from my ASA 5510:
<166>%ASA-6-110001: No route to 127.0.0.1 from <IP address of ASA 'outside' interface>
We do not have failover configured, however the 'internal control 0/0 interface is up/up with 127.0.1.1' (although all of my other ASAs have this interface and IP address, but do not generate the syslog)
Could this be a device (PC or printer) on the 'inside' which is trying to ping its own loopback address, but instead is getting forwarded out through the ASA?
