I am looking for the types of ICMP to filter in order to eliminate ping and traceroute from the Internet. I want to continue to ping and traceroute outbound. I have read several of the archives and seen several messages about filtered ICMP causing path MTU to not function. I have several web servers and mail servers behind the filter router. I don't want to cause any problems with the performance of these services. Also, by filtering these will I eliminate PingFlood attacks? Thanks... __________________________________________________ Do You Yahoo!? Bid and sell for free at http://auctions.yahoo.com
