fw monitor -m iIoO -e "accept dst=192.168.27.198;"
fw monitor -m iIoO -e "accept dst=192.168.2.3;" -o /var/tmp/SOCD00008413514
fw monitor -m iIoO -e "accept src=192.168.160.45 or dst=172.16.160.45;"

fw monitor -m iIOo -e 'accept src=10.33.76.82 and dst=10.33.76.82;'

The little "i" means the packet is incoming to the interface specified.

The big "I" means the packet is incoming to the checkpoint filter

The little "o" means the packet is leaving the filter
