tcpspy log interpretation

[Hanasaki JiJi <hanasaki@hanaden.com>]

The below log entries are from tcpspy in syslog.  What do they mean? 
they are from the firewall which is running a transparent squid proxy 
and iptables.

noone inside the firewall could have hit those external IPs for any reason.

thanks
