pf logging only no active filtering

[Malte Graebner]

Hello folks,
is there an option, to only log all stuff going on via "log" command and 
without taking any action to traffic flow itself ?

I'm migrating an existing iptables firewall, and i want to set the new 
one in front of it and bridge the traffic to the old one. Meanwhile I 
want to test my iptables -> pf ruleset and snooping the bridge traffic 
with pflog and tcpdump, but the "new" firewall needs to let the traffic 
flow without take any actions except logging.


br,
