How do I ignore arbirtary ports with out rewriting all the rules?
For example, kazza runs on port 1214; how can I make all my rules not
trigger on port 1214 traffic?

pcap filter of 'not tcp and port 1214 '

or

pass tcp any any <-> any 1214
along with using snort -o

Beware that this will open one for attacks due to clever attackers
using 1214 as a source port for the attack.

Someday, snort might be able to tell what kinda traffic it is and
possibly ignore it based on that.
