Hello, all. I recently got my Buffalo wireless router/AP up and running at home and the log has given me the few entries of note the last couple of days:

IP SPOOFING attack: 10.130.192.1 255.255.255.255 2007/07/18 11:44:29 - 2007/07/18 12:19:19 1130

The Smurf attacks and the NMAP port scans I get. Is my router perhaps causing the IP spoofing episodes above? I assume there's no need to worry in any case since the router is denying the events from happening. Still, I am curious if I should report them to my ISP.

Thanks.
