Securing Cisco Routers http://www.cisco.com/warp/public/707/21.html http://www.cisco.com/warp/public/707/3.html http://www.cisco.com/warp/public/707/4.html 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.

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..
