Transparent bridge firewall, how to define WAN as unnumbered?
How do you setup a transparent bridge between OPT1-WAN, using the LAN interface for management without assigning an IP to the WAN interface? The GUI complains if you set it to static and don't add IP info.
If I leave the WAN interface at DHCP, my cable modem assigns a 10.x.x.x IP to it but these leads to erratic behavior. I had it working for a while, but with a lot of traffic graphed I couldn't account for with tcpdumps on the host behind the bridge or the pfSense install itself; after a while it stopped altogether.
Or is the better practice from a pfSense perspective to bridge WAN-LAN and manage from OPT1? Either way I need to supply an IP for WAN1 because of the GUI's complaints.
I'm not sure if it is possible on 1.2.x, but on 2.0 beta you could probably configure WAN as "none" for the address type.
