Bridge WAN to your OPT interface, keeping the configuration on your
servers the same.  Enabled filtered bridge.

Due to ARP caching on your ISP's router, you may have to wait several
hours before the WAN interface will respond since the MAC address will
change.  The ideal solution would be getting the ISP to clear the ARP
table on the router, but depending on the situation and ISP, that
might be difficult to get done.
