Few weeks back I had to do an installation for my work in the UK.
We had some problems to get the connection correct. And I had to find out which configuration I had to use.
The main problem we found was which configuration we needed. Because me and my colleague are used to configure Dutch Internet Connections with Dutch ISP’s.
But aftersome search I found the correct configuration we needed. And below is what you need to use.
