Ubuntu Networking :: Unlocking Vonage Linksys RT31P2?

I couldn't find any details on how to do this on Ubuntu, so I figured I'd share for anybody who needs to do that. I got this adapter from a garage sale, it's meant for use with vonage service, it has a web interface with disabled voice tab, and a hidden voice admin page. My goal was to access (unlock) those pages, so that I can use it with one of the free sip providers.

The main thread on how to do this is over at bargainshare forums, the only thing I'm adding here is how to do it on Ubuntu as opposed to windows:[URL]... I will write the simplist path using typical defaults, if your setup deviates or if one of the steps below fails, please refer to the original guide at this link to sort things out. Important note: the pc used in the procedure shouldn't be connected to the internet. Internet access is only needed to get files, programs and instructions, either before using the pc for this procedure, or through a separate pc.

Adapter setup:Do NOT connect the adapter to the internet especially if it has been out of service for a while. Connect an ethernet cable to one of the lan ports on the adapter and in a browser go to 192.168.15.1, this is the default lan gateway address. When prompted to log in use admin/admin again that's the default First thing needed is to flash a special unlocking firmware that allows the adapter to acquire clear text configuration file (as opposed to the encrypted vonage one). After downloading the unlocking firmware from guide above, go to the Administration page then the tab for flashing firmware. Select the firmware file you just saved and let it flash, you'll be prompted to log in, I used user/7756112 , more can be found in the guide, if successful, you'll get a message to that effect. Now firmware version should be 1.7.02 and voice 2.09 LId Next we need to get the adapter to get our configuration file, create one as mentioned in the guide above, meister_sd method, put the file in a folder of your choice, we'll need to use that as our tftp root folder later Now we configure the adapter to talk to the pc, under the setup page of the adapter set "Internet Connection Type" to Static IP and assign the adapter a static IP address, e.g. 192.168.1.88, then set the default gateway and DNS1 to a static IP address that you'll later assign to your PC, make sure it's on the same subnet as the IP address you assigned to the adapter, e.g. 192.168.1.99, save the changes Switch the ethernet cable to the wan port of the adapter, so it's connected directly to the pc, no crossover cable needed in my experience, turn off the adapter until we setup the pc

PC setup:First we need dnsmasq package from synaptic. This package can provide dns, dhcp, read only tftp daemons, outstanding piece of software. during the installation, it will automatically start with it's default settings. we'll shut it down so that we can start it with different command line options:

Code:
sudo /etc/init.d/dnsmasq stop Now we configure the pc to act as a gateway and dns server temporarily, System->Preferences->Network connections , then edit the ethernet interface we're using to connect to the adapter, under IPv4 settings, set the method to manual, then add an address entry with the IP address used on the adapter for dns and gateway, ie 192.168.1.99 and gateway and dns as 127.0.0.1 Now we need to start the dns and tftp daemons:
