I think you are trying the right things in the wrong order.
This is how I would do it:
1. Put your OPT on a totally different Subnet (I use 192.168.x.x for
LAN and 172.16.x.x for OPT) - no bridging on OPT interface... Just for
clarity and to avoid fat fingers... 192.168.x.x and 192.169.x.x are
simple to get crossed...
2. Set Belkin to bridge/ap only (no routing) or you may just need to
connect Belkin LAN interface directly to M0n0 OPT interface (i.e.
don't use WAN). Give the Belkin LAN an IP in the 172.16.x.x subnet. I
assume the ap/router has multiple ethernet interfaces (WAN and LAN x
?)... My Belkin AP has one ethernet interface - but it is not a
3. Disable Belkin DHCP - enable DHCP on m0n0wall OPT interface (use a
range that excludes Belkin LAN).
4. Set a firewall rule on m0n0 to pass any traffic on OPT interface
(from OPT subnet) to any destination NOT LAN subnet (check the NOT
OPT Rule Details:
Source: (do not check box)
Type: OPT subnet
Source port range from: any
Destination: not (check box)
Type: LAN subnet
Destination port range from: any
Log: only if you want to track where you wireless guests are going...
I would log to remote if you check this...
Description: Default OPT -> Any (not LAN)
You will be using the Belkin like an access point. Wireless clients
will get IP from m0n0 on 172.16.x.x subnet with m0n0's OPT IP as
gateway and DNS (if DNS forwarding enabled). Firewall rule allows
traffic from OPT subnet to anywhere except LAN subnet (i.e. Internet).
LAN will be able to see OPT clients, unless you edit the default LAN
rule destination to be "NOT OPT subnet"
