Wireless bridge issue

[nanomu]

So I'm trying to setup a seemingly simple wireless bridge between two floors in my house. Both routers are ALIX 2c0 with pfsense 1.2 release. I am including below my current topology and attempted configurations. Router 2 (upstairs) is able to receive an IP from the DHCP server on router 1 and associates just fine, but neither router, or the machines behind them are able to ping the other. Pings fail with a "host is down" error, which leads me to believe router 1 is not receiving the ARP request from router 2.

(internet) - (DHCP | 192.168.1.1) - - (wireless) - - (192.168.1.2 | 192.168.1.3)
…..................................|........................................................................|
......................(Downstairs LAN)..................................................(Upstairs LAN)

Router 1:
WAN: DHCP
LAN: 192.168.1.1
OPT1: Bridged to LAN
DHCP server: 192.168.1.1xx

Router 2:
WAN: 192.168.1.2, gw 192.168.1.1, assigned to ath0, BSS mode, "block private networks" unchecked
LAN: 192.168.1.3
OPT1: N/A, ath0 assigned to WAN (have also tried with ath0 assigned here)

Firewalls on both routers are "wide open" (all interfaces have any<-->any rule).
I have attempted this with "filtering bridge" both on and off.
I have attempted this with both Auto outbound NAT and Manual outbound NAT on router 2.
Both routers and all machines on both LANs are on same subnet (192.168.1.x).

So.. What obvious configuration setting am I missing to enable this setup to work?

You cannot bridge in Infrastructure or Ad-hoc mode.
So your second router will never be able to bridge it's WAN(wireless) and LAN(wired).

The best is probably if you just have multiple subnets and route them.

something like:

downstair 192.168.1.0/24
                      |
                      |
                      |
              192.168.1.2
                    2c2
              192.168.10.1
                      |
                      |wireless_link
                      |
              192.168.10.2
                    2c2
              192.168.2.1
                      |
                      |
                      |
        upstair 192.168.2.0/24

Then create on the pfSense downstairs a static route pointing to the IP of the upstairs-pfSense for the upstairs subnet.

I have some basic config files located on this post.
