"Nat pass" not working in pf?

nat pass on fxp0 proto tcp from (ed0:network) to any -> (fxp0:0) static-port 
Still, filtering rules are still being used. I create rule: 
"pass in log quick on ed0 from (ed0:network) to any keep-state allow-opts 
By pfctl -s state I can see, that state for packet is created, but incoming 
packets are not using it, because they are being dropped on external interface 
fxp0, despite the "set state-policy floating".
