Maybe it should be a pre-defined filter that the manufactures include in the basic software configuration. If we put some pressure on Cisco/Bay/Ascend/Livingston etc....... maybe we can get it done there, so that we don't have to educate new people. Alex P On Thu, 21 Aug 1997, Jon Green wrote:

That is, no more lying about source addresses.Every time I show a customer of mine how to configure a router, I try to educate them on this. We need some kind of massive marketing effort to get this out to people though. People would do it, but nobody knows about it. Maybe we should get CyberPromo to spam all the technical contacts in Internic's database to tell them how to do filtering. :) -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 * -------------------------------------------------------------------------
