Quick and dirty fix: # route add 1.2.3.4 127.0.0.1 All ACKs to 1.2.3.4 would not be able to reach their destination, and no TCP connections could be established this way. Moreoever, no UDP or ICMP packets would reach the blocked IP address. You can also block a whole subnet this way. The real solution is to enable a firewall at the interface level, or perhaps even add an ACL on your router (if you control your upstream router). -- Cordula's Web. http://www.cordula.ws/ _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
