just block all the connection to yahoo msg server: scs-fooa.yahoo.com scs-foob.yahoo.com scs-fooc.yahoo.com scs-food.yahoo.com scs-fooe.yahoo.com scs-foof.yahoo.com that is the list I got so far, I am rejecting the connection to those servers after my DNS chain rules so when we put the servers name instead of ip address, it can resolve all the ip address to that server. if you just want to block certain range of ip from the LAN, check the lates patch-o-matic for iptables. http://www.netfilter.org/ regards.
