I had ATT DSL service in Dallas, and was told that I could use the same DSL modem (Netopia, marked 3347-02-1002, S/N 32683792, MAC 00:0F:CC:F2:B7:10 with labels on the modem, software version 7.6.1r7 and product ID 1225 according to the modem home page) for my ATT DSL service in Austin.
In Dallas, my DSL service was configured for a static public IP address, which required that the modem configuration address be changed from the default 192.168.1.254 to 126.96.36.199 Although the modem still responds to ping at this address (indicating that the problem is not with the local network configuration) I have been unable to access the modem configuration either thru the web interface or via telnet, neither will connect. Note that while in Dallas I had no problem accessing the web configuration via the 188.8.131.52 address.
The only resolution to this I can see is to do the hardware reset (by pressing the recessed button on the rear of the modem). Before I do this, I would like to find out what, if any, settings particular to ATT DSL service (ie, which were changed by ATT before the modem was delivered) will be lost and need to be restored before attempting to connect the modem to the phone line for initial DSL service setup. The only documentation I have been able to find for this modem refers to a different firmware version (7.7.4) and is unclear on the effect of doing the hardware reset:
"If you press the factory default button for 1 second, when you release it, the Gateway will perform a factory reset, clear all settings and configurations, and reboot. Do not hold the button down too long (5 –10 seconds). This will destroy any saved default settings as well." (Administrator’s Handbook Embedded Software Version 7.7.4 Motorola Netopia 2200, 3300 and 7000 Series Gateways, page 206)
There is no explanation of the difference between "settings and configurations" and "saved default settings". I would guess that any ATT service specific settings would be part of the "saved default settings", but I would like to find out for sure before proceeding.
Also, I will require the modem to operate in "bridge mode" ie, passing the public IP address which it obtains via DHCP (note, my Austin service is DHCP and not static public IP address) thru to a firewall device on my local network which will handle NAT and local network DHCP. I assume that this can be accomplished by means of the Ethernet Bridge/Enable System Bridge setting in the modem configuration (page 105 of above referenced documentation), and that this will need to be configured before connecting the modem to the phone line for initial DSL service setup. If these assumptions are incorrect and/or incomplete, please advise.
