What I am asking is, do you want the wireless clients
to have the same IP subnet as the wired clients?
For example, if you have a LAN with network number 192.168.1.0
(i.e., netmask 255.255.255.0) and you want Wireless clients
to have the same IP address range, eg 192.168.1.2 or 192.168.1.200,
then you need to bridge. I don't know anything about that.
>> Are others bridging wireless to wired?
A more likely example is, you have one routable IP address
for example, 126.96.36.199, and you want m0n0 to *route* from
the Wireless network to the WAN,
(I believe this implies automatic NAT, since the
WAN only has one IP, but the "NAT" screens are not used).

I think what you need to do after you set up WAN and LAN
through the console, is log in via the LAN
and go to the Assign Interfaces screen, and click the
+ at the bottom of the list)
