Backwards - the * means to everyone. Obviously, if we knew who was 
sending us the packets, it would defeat the entire purpose of Tor. This 
lets you set up certain IP ranges so packets can't be sent to them 
(commonly, localhost and other LAN IP blocks - occasionally, 
Tor-disliking sites like Slashdot or Wikipedia.)
