We currently use a bunch of WRT54GLs as wireless clients and to bridge
the wireless and wired interfaces, we set "option wds 1" (and "option
mode sta") in /etc/config/wireless. This wiki page has slightly more
details [1]
My understanding is that this uses 4 address frames, and that the access
point must also be configured with "option wds 1", or support 4 address
frames. I haven't explored ARP NAT, but my understanding is that this
might enable bridging wireless and wired interfaces even if the access
point doesn't support 4 address frames?
Also we use the brcm47xx platform, this wiki page [2] has documentation
on WDS with the brcm-2.4 platform, but I haven't tried that either.
We also use the instructions from this wiki page [3] to put all wired
interfaces in the same VLAN ("lan")

I was wondering if it wa possible to successfully bridge between a wired
and wireless ports on a WRT54GL. I've tried this before but never got it to
work. I've also found some reports that the hardware onteh WRT54GL can't
handle it.
Last I checked:
- this works fine if the WRT54GL's wifi card is in "master" mode
(i.e. it is the access point).
- OTOH it does not work if the wifi card is a client connecting to some
existing network.
Also the first case is well supported under OpenWRT, so I suspect you're
in the second case situation.
All hope is not lost, since a few years have passed since last time
I checked.

seems to say that it can now be made to work using some ebtables magic.
