I followed the directions to set up pfsense in bridged / transparent mode per the instructions at http://doc.pfsense.org/index.php/Configuring_pfSense
However I can not get a dhcp address from my internet router.
It works fine if I set my machine to a static address – I have internet connectivity.
But if I set to dhcp, I never get an address. I can get an address fine if I plug directly in to the WAN side of the network.
Any ideas?

Part of DHCP is broadcast traffic.
Relevant excerpt from pfsense forums: http://forum.pfsense.org/index.php?topic=13351.0
Firewall rule recommended to add:
UDP * 67 - 68 * 67 - 68 * pass dhcp traffic
You may also have issues with UPNP and other broadcast traffic if your use is across the bridge. (Print server or network shared drive on router.)
