One thing to be aware of when bridging Option-1 interface to to WAN
interface: Any ports forwarded via NAT to the LAN interface are not usable
on the Option-1 interface. I had port 80 forwarded to one of my LAN hosts
and had to remove this NAT rule before I could get any of the Option-1
Public IPs to work on port 80. Otherwise WAN to Option-1 bridging is working
great and hosts on the LAN can talk to the Option-1 hosts.
