I added the firewall rule but I still can't ping the LAN address.  Do I
need to turn on proxy arp on the m0n0wall or make any other changes to
get my workstation to see the other side?

Don't NAT at all.  Assuming your workstation is on the 10.x.x.x network,
if you disable NAT and put in the appropriate firewall rules, you'll be
able to get to anything behind m0n0wall.

If you want to do it without disabling NAT, 1:1 NAT for each AP is
probably the best solution.

Given that the WAN side is on a private IP network, you probably don't
want to be NAT'ing anyway since you'll then end up double NAT'ing when
users go out to the Internet, and that just gets ugly...
