I have the first setup you mentioned up and running smoothly at home.
I didn't have to tweak anything about DMZ and stuff.
The modem has IP 10.0.0.138 (default),
The SPA3102 has 10.0.0.139 on the modem side, 192.168.0.1 on the
The wireless router has 192.168.0.2 on the SPA-side, 192.168.50.1 on the
In my HOSTS-file I have entered the following (air-code!):
