You can either apply the iprange patch from patch-o-matic or, if you do
not want to or cannot patch, break it into several rules using subnets. 
I've used SubnetCreator (http://subnetcreator.sourceforge.net) to help
calculate subnets from ranges, e.g., 
192.168.0.2/31
192.168.0.4/30
192.168.0.8/31
192.168.0.10/32
