# this is my crazy rule, watch out!
var STASH $HTTP_PORTS
var HTTP_PORTS [4323:5000]
alert tcp any any -> any $HTTP_PORTS (msg:"crazy rule"; sid: 
111111111; ... ) var HTTP_PORTS 9999 alert tcp any any -> any 
$HTTP_PORTS (msg:"crazy rule"; sid: 111111111; ... ) var 
HTTP_PORTS $STASH # okay, the craziness is done.


I remember when a certain Snort Rules Nazi did just this with snort.org
rules because commercial IDS vendors were automatically sucking down the
snort rules and claiming they were theirs... But he wasn't so nice with the
rule... I guess that's one way to stop them. :)

Cheers,

Jeff
