[newbie] OT: Port Scan?

[Chris Ruzin]

I've got a D-Link DI-604 router for my small home network.  I have it 
automatically send me the log file when it reaches a certain size.  In 
the last few days, I've been getting a copy of a the log file several 
times a day.  And it's always the same thing:

Feb/09/2004 22:06:32
 Drop TCP packet from WAN src:66.65.215.6:62986 dst:162.40.161.66:8980 
Rule: Default deny
Feb/09/2004 22:06:32
 Drop ICMP packet from WAN src:216.176.95.198:3 dst:162.40.161.66:1 
Rule: Default deny
Feb/09/2004 22:06:32
 Drop ICMP packet from WAN src:216.176.95.198:3 dst:162.40.161.66:1 
Rule: Default deny
Feb/09/2004 22:06:31
 Drop ICMP packet from WAN src:216.176.95.198:3 dst:162.40.161.66:1 
Rule: Default deny
Feb/09/2004 22:06:30
 Drop TCP packet from WAN src:24.192.222.186:4697 
dst:162.40.161.66:6346 Rule: Default deny
Feb/09/2004 22:06:28

Of course, the log file is MUCH bigger, but the vast majority of 
entries are like this.  Is this a port scan of somekind?  I don't know 
how to read firewall log files like this.  Can anyone shed some light 
on this for me?

Thanks,
Chris
