We're also using the following extended access list (along with anti-spoofing filters) to prevent smurf attacks from originating from our network:
access-list XXX deny ip any 0.0.0.255 255.255.255.0
Folks, this is a bad idea. There are lots of completely valid IP addresses out there that end in .255. True, most of them that end in .255 ARE broadcast addresses, but if people implement this kind of filtering on a large scale, it really breaks classless IP. But that's just IMHO. :) -Jon ----------------------------------------------------------------- * Jon Green * "Life's a dance * * jcgreen@netINS.net * you learn as you go" * * Finger for Geek Code/PGP * * * #include "std_disclaimer.h" * http://www.netins.net/showcase/jcgreen * -------------------------------------------------------------------------
