Your rules have no "sid" keyword in them. You must put an sid number in

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.

pass icmp $DI200 any -> $3825ROUTER any

Thanks in advance.
