Hi, It is OK, I knew that it wasn't an alarm system, it is just that those connections are so expensive in my country these days, you only see them used for alarms

This is a whole new situation, as I and our fellow members, probably did not realise that you had a dedicated connection (line).

Now, I have a few more questions:

1. Do you need two computers at home to connect, or could you manage with one? I would include connecting the two at home if required, as a local network.

2. I assume that you need the two at work to be effectively independent?

Please ignore my comments on IP addresses, with a dedicated static link the addresses remain the same unless you choose to change them.

Also, as a dedicated line, there is no internet, so no security risk, UNLESS you let something onto a machine that does connect to the internet.
