I read this post http://forum.pfsense.org/index.php/topic,12101.0.html
titled "wireless not giving IP when bridged with LAN" and it took me a long time to figure out how to implement it on my box, so I offer this clarification.
I'm running 2.0-ALPHA-ALPHA-nanobsd built on Sept 15th, 2009 on an ALIX 2D3 board.
I have attached below an image of my "interfaces assign" page from the web GUI. This setup defines OPT1 (renamed WLAN) as my wireless interface, OPT2 as one of my 10/100 interfaces.
The bridge interface includes OPT1 and OPT2.
I didn't have to create ANY new firewall rules for this to operate smoothly. Clients on the wired LAN or WLAN can get to the internet and can get to each other.
The second image is from the System => Advanced => System Tunables page.
The DHCP server setting are unchanged from the default settings (running on the LAN interface.)
