Re: address spoofing

but the uglier symptoms are packets from my own address space

  deny ip 147.28.0.0 0.0.255.255 any (6 matches)

I have vague memory of an old attack using ping with source address
equal to broadcast address of the target net.

That is over and above TCP connection hijacking, server attacks with
half openned TCP connections and such fumy things.  On the other hand,
given you seem to have only 6 incidences, looks more like screw up than
real attack.

John Leong
