With help from Manuel Kasper, here is the setup that works with three 
radios and two relays:

10.3.2.4  GW 10.3.2.1
                                             GW x.x.x.25

Internet router is x.x.x.1.
DNS is x.x.x.2 (Authoritative)
        x.x.x.3 ...
        x.x.x.4 (Caching)
        x.x.x.5 ...

m0n0wall is x.x.x.6.
NetNimble WRIP 1 is x.x.x.22.
NetNimble WRIP 2 is x.x.x.26.

Clients are DHCP with 10.1.x.2-254, GW 10.1.x.1.

So far everything is working except for the ability to telnet/http to 
my two NetNimble relays from my wired network.  I can ping them just 
fine, but I can't access them.  I have my firewall wide open currently. 
  I can access them from anywhere on the wireless network. Strange.

Anyway, thanks Manuel!
