IP Spoof logs ~~~

[scjlin]

Currently I am running NetScreen 25 as my firewall. I start experiencing the strange log at my NS25 since last month. The log are continuing logging every 15 seconds.
These are detail logs:

* 2004-02-16 11:08:31 alert ip spoof, From 10.2.2.2 to 224.0.0.10, using protocol 88 (on zone Untrust,interface ethernet3) occurred 1 times
* 2004-02-16 11:08:26 alert ip spoof, From 10.2.2.2 to 224.0.0.10, using protocol 88 (on zone Untrust,interface ethernet3) occurred 1 times
* 2004-02-16 11:08:21 alert ip spoof, From 10.2.2.2 to 224.0.0.10, using protocol 88 (on zone Untrust,interface ethernet3) occurred 1 times

The IP Spoof is from my router interface which is 10.2.2.2 (Next to my NS25 trust interface 10.2.2.1).

Any suggestions, comments or solutions are appreciates,

Thanks,
