Thanks,  I have another query, if the last rule does not include a queue 
directive will the the traffic pass through altq or will it just pass 
thought the system bypassing the queue (see example rules below)?


Thanks

Tom

pass in on em0 from any to any queue normal
pass out on em0 from any to any queue normal

pass in on em0 from 172.17.0.123 to 10.0.0.123 queue vidconf
pass out on em0 from 10.0.0.123 to 172.17.0.123 queue vidconf

pass in quick on em0 from 172.17.0.0/16 to 10.0.0.0/16
pass out quick on em0 from 10.0.0.0/16 to 172.17.0.0/16
