[Snort-users] Pass Rule not working?

I've been getting alerts in ACID because of ICMP packets. The message is 
ICMP Destination Unreachable (Communication Administratively Prohibited)
I know this particular issue has been addressed previously and I think I 
understand why it's happening. The servers on my Home Net are trying to 
ping to places that they aren't allowed to ping and the packets are being 
returned by an intermediary device. Trying to be clever, I wrote a pass 
rule in my local.rules file:

pass icmp any any -> *.*.*.* any (itype: 3; icode: 13)

I'm still getting errors.

What'd I do wrong?
