I wanted to route multicast between subnets with pfsense 1.22 , but it was not working. So I bridged my wifi (opt1) to lan and added some rules to permit dhcp & multicast to work for a freenas-itunes server on lan to wifi.

I also was having some throughput issues with the onboard pfsense netgear wa311 (802.11B pci) wifi(opt1) so i added a dlink router configured as a access point to help (802.11g+).

Here is a screenshot of my initial lan rules that solved my problems.
Thanks again to all on the message boards & the dev's.
