I have a little experience in networking but by no means a networking engineer hence would appreciate your help and advice.
At present, we have four small offices under one business; each having an ADSL2 connection provided by their ISP. I believe that it is an MPLS network at their end.
The connection allows the staff Internet access and also access to a secure web-based database which can only be accessed via this link (in other words, the application cannot be accessed from home or elsewhere) which is a business requirement.
The ISP are responsible for configuring the 'meshing' to allow routing between the sites.
We are hoping to host their servers in our offices and each of the sites would be purchasing a separate business fibre broadband line. It is hoped that we would route all the traffic required for their database traffic through the existing ADSL2 line and all Internet and local server traffic via the new fibre line.
My questions are on the lines off
1) firstly if this is achievable, what try of Cisco switch would I look at purchasing to carry out the routing?
2) would I need any other hardware for both the client office and our office?
3) most importantly, how would I configure the network and traffic separation on the clients side?
I realise there will be more questions you will need to clarify therefore I will try my upmost to respond as soon as I can.
