Snort is telling me that I have duplicate pass rules.  Do I have to
define the whole rule in order to allow the two pass rules to work?
The first one worked fine until I added the second one.

Oct 22 09:10:28 atlas snort[4680]: FATAL ERROR:
/etc/snort/snort-eth2.conf(58): Duplicate rule with same gid (1) and
no sid.  To avoid this, make sure all of your rules define an sid.


var HOME_NET [172.31.1.0/24,172.31.2.0/24,172.31.3.0/24,172.31.4.0/24,172.31.5.0/24]

# Set up the external network addresses as well.  A good start may be "any"

var EXTERNAL_NET any

#Ignore redirects from the main router to internet gateway
var 3825ROUTER [172.31.1.1/32]
pass icmp $3825ROUTER any -> $HOME_NET any

#Chatty Minolta copiers
var DI200 [172.31.1.223/32,172.31.1.240/32]
pass icmp $DI200 any -> $3825ROUTER any

Thanks in advance.
