Hello,

Last couple of weeks i'm getting more and more spoofed scans on my
firewall. All scans are icmp or port 53 (domain). Mostly 'they' first send
a few icmp packets and then a scan for port 53 trying to do a reverse
lookup for my ip.

Are there more seeing this type off scans and is there a way to substract
the real scanner (ip) from the list ip's ???

Greetings,

Richard.
