Please note that I am broadly familiar with PC networking and TCP/IP, so I don't need the idiots guide to do network configuration, I just need to know the basics for making the following change happen.

I have NTL broadband which is working perfectly. Unfortunately (or not) I have a need to use a VPN tunnel to connect to a remote location. Problem is that VPN won't work because both sides of the VPN tunnel are using the same IP subnet (192.168.0.x/255.255.255.0). So one of them has to change.

Configuring my end of the network I have no problem with, until I get to the NTL cable modem bit. I don't even know what it's IP address is but I guess it'll be on the 192.168.0.x subnet (feel free to correct me if I'm wrong!). I'm assuming that I will have to change the CM's local IP address.

So, how do I go about connecting to this cable modem to carry out a change of its IP address? I seem to recall from when the CM was installed it was configurable via a browser, but for the life of me I can't remember the details. If I could get to the CM's control panel I'm sure I can figure the rest out.

I'm on a 10M connection and the CM is a small blue box about 4x5x1in. No make or anything I can find. It has both an RJ45 and a USB socket on its rear end (only the RJ45 is connected). I'm sure this is a regular NTL CM.

So basic information about how to get to the CM control panel (with passwords if necessary) would be gratefully received.

Cheers,
Andrew
