How to start the bridge in pfsense 1.2

[afvadmin]

I have setup my vpn and it works fine i need to access some of the domain resources and the only way i can do this is through a wins server or a network bridge, and well im going with the network bridge i need some help on bridging pfsense. i noticed people say to follow this

To create a bridge in FreeBSD, you need to have the tap and bridge drivers in the kernel. The easiest way to do that is to let the ${PREFIX}/etc/rc.d/openvpn.sh script do it for you. Setting openvpn_if="tap bridge" in /etc/rc.conf will do that.

but were do i get this in pfsense
