I don't think you can bridge the LAN to the WAN. You can only bridge
an OPT interface to another interface (LAN, WAN, or other OPT). You
would need to add a 3rd NIC, bridge to WAN, and set firewall rules to
meet your needs.

If you only want to use the bridged network, then the LAN interface
would become a "Management" interface/network... and for all practical
purposes the OPT interface would be your "LAN" (although it wild be
labeled "OPT" or what ever you renamed it - I don't think you can
rename the "LAN")...
