You can now convert your unlocked BT Home Hub 2.0 to an ethernet router. That means you can connect any ethernet-based WAN connection to ethernet port 4, and NAT (Network Address Translation) will be performed. Examples include your Uni Campus network, Virgin Media, ADSL Modems or BT Infinity! Note, you will need to unlock your BT Home Hub 2.0 first, instructions on how to do this can be found here.

Requirements

A telnet client. On anything running XP or below, you should have the Microsoft Telnet client installed by default. For Windows Vista/2008/7 users, please see this page

Notes

The web interface for the BT Home Hub will become kind of inaccessible after this mod, i.e. visiting it will throw an error 500, internal server error. The easy solution to the problem is to browse to /settings.lp instead, i.e. http://192.168.1.254/settings.lp

Method

Open up your favourite telnet client, on Windows, open the command prompt and type (on Mac OSX, open Terminal instead):

telnet 192.168.1.254

You should now see something like the following:

Now enter admin as the username, then enter, then enter your password followed by enter. Now, enter each line one followed by enter, and you should be done!
