that is not really true iptables -A INPUT -p tcp -m multiport --destination-port 25 -j REJECT --reject-with icmp-host-unreachable i still brought up http://www.linuxtopia.org/Linux_Firewall_iptables/x4550.html and yes, i use it regulary to block complete machines in cases where they do even not need to know the other side exists ________________ you can even respond like a router with "network unreachable" and use all this things even for outgoing rules, emember that iptables is the base of many routers/firewalls iptables -A INPUT -p tcp -m multiport --destination-port 25 -j REJECT --reject-with icmp-net-unreachable
