Thanks for the reply. I bought it from Newegg. There was no mention of a special provider. Nevertheless, after I messed with it for a while, the configuration menus simply appeared out of nowhere. There is obviously some firmware problems so I upgraded it to the latest which is supposed to be version 3.2.1 (Build: 5757EX). However, I noticed after upgrading that all the Google Voice setup menus disappeared.
I still don't have it working per se, but at least now I can get to the configuration menus. Here is what I did to get where I'm at:
1) First, plug the computer directly into the LAN port of the 302 and access it at 192.168.10.1 .
2) Go into System Management->Device Admin and change AccessFromWAN to checked.
3) Submit, Reboot.
4) Unplug the computer from the 302's LAN port and then plug the 302's WAN port into the router or switch. (Yes, plug it into the WAN port not the LAN this time.)
5) Now the device can be accessed from anywhere on your Lan.
6) On my router, it came in as 192.168.1.101, and shows up in the Tomato device list as an Obi202.
There was definitely something flakey about the firmware not showing the config menus. I hope that they got it fixed in the latest version of the firmware.
