Tor ExitNodes accept ISO country code or Ip address..
Trying to connect Tor ExitNode like..
ExitNodes {X.X.0.0/16},{X.X.0.0/20}
StrictExitNodes 1.
but it's not working. so it is not possible or i'm doing wrong..
According to the torrc
manual page the correct syntax is
ExitNode X.X.0.0/16,Y.Y.Y.0/24
So it should work when you leave out the curly braces.
