I've created a set of interface aliases (eth2:0-eth2:13). How can I use these aliases to control traffic on their respective interfaces? For example, when I say: $IPTABLES -A INPUT -i eth2:0 -j DROP I get a message telling me that I have a wierd character and that alias are not allowed. Is there a way to use aliases in the manner similar to the above or must I block entirely by IP? Thanks, Charles
