Think I'll need to RTFM concerning pass rules. Haven't used them before.pass rules are pretty straight forward, just make sure you pass the -o parameter to snort's command line.Also think your pass rules through carefully.. make sure you don't wind up with a rule that is the equivalent of "pass any any -> any any".
After reading a bit I ended up with a pass rule like below: pass icmp $ICMP_WHITELIST any -> $HOME_NET any (dsize: >800; sid:499;) I kept the sid in order to know what alert rule I'm letting pass.
