You should block RFC 1918 addresses at your perimeter routers.
I used to have a list of the reserved addresses, but cannot find them right
now.
Multicast and broadcast should be blocked, unless needed for some reason.

Subject: How to block Spoofing ??
Hi All,
I have seen many IP addreess tried to establish connection with my
network, I came to know this from my firewall log but these are not really
from Original hosts. I feel somebody is spoofing the IP and attacking my
network.. hence I would like to block this spoofing,
Is anybody know how to block this spoofing? and IS there any special
software available to identify spoofing?
I feel the spoofing option provided by checkpoint is not effective..
Since it can block pockets which arrives to external NIC with Private
IP/LocalNet IP addresses only...
Any input regarding Spoofing is appreciated..
Thanks & regards,
MOHi
