it possible to specify a negative variable value for a variable? Meaning: var EXTERNAL_NET !HOME_NETThe bang is just an idea of something that would negate the value so that my external_net variable would be any ip/subnet that isn't part of the home_net variable. Is there anything in place to allow for this? Could there be? Since so many of the rules are based on the external_net variable, it's very frustrating that it must be set to ANY for my configurations because I can't specifiy every subnet on the Internet...or can I?
Yes, you can do that.. lots of people use that exact setting. 1) make sure HOME_NET has proper braces around it if it's multiple IP ranges. 2) make sure HOME_NET isn't "any".. because !any is nothing. ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
