I have just added a third nic to my m0n0wall. I would like to have one 
nic accepting my inet connection, and the other two serving my two pcs. 
Obviously I would like both pcs on a LAN being able to share resources, 
and sharing the WAN connection. All three nics are showing up and being 
recognised.

Do I need to bridge the Optional 1 interface (OPT1) with the LAN 
interface in order to get this to work, or assign the OPT1 interface its 
own ip, and create its own set of firewall rules?

Thanks
