The key, I think, is the capability of your wireless router. Can it act as
a bridge? If so, you may have the choice of setting it up with or without
an ip address. Normally, you would want it with a ip address, so that you
can easily http in and reconfigure it as necessary.

If you can set it up as a bridge with an ip address, the address will be on
the internal network, 192.168.1.0, not the DMZ network. 

If you cannot set it up as a bridge, it will need two ip addresses, the
"external" address on the DMZ network, and the "internal" network on the
192.168.1.0 network. It will then do NAT'ing, which will require you to put
a route on your firewall, letting it know where to send the 192.168.1.0
traffic.

Good luck
