When the nat re-writes packets these can be seen by the firewall as bad trafic... You wont have this problem if you have configured your local lan as a trusted network though - NB this is the same as having app level control as all packets will be allowed...
There is no point having a firewall behind a nat IMO...... Waste or resorces.... i do recomend that a firewall is run for app control but it should be set to allow local trafic....
Firewalls behind a nat can cause a multitude of problems !!
