Here is the scenario. One small office with 30 employees. The office is divided to 3 departments. DepartmentA , DepartmentB and DepartmentC lets say. They have an internet connection ADSL corporate 512Kb/512Kb download/upload.
They want from me to divide the internet connection bandwidth as follows: 60% internet bandwidth utilization for Dep.A, 30% for Dep.B and the rest for Dep.C . They also need to setup a VPN connection for VOIP through IP cordless phones so they can communicate with their main office to avoid the cost of external calls. Also Dep.B must be connected to the internet through a wireless connection only.
They need all these by having at my disposal 2 unmanaged switches, one Cisco 871W wireless router and the corporate internet connection 512Kb/512Kb download/upload.
Can I implement this solution according to what I have? I asked them to put at least another home ADSL connection just for VOIP but they said the ministry of communication forbids the use of home ADSL connection to companies.
I will give the points to the one who has setup something similar or at least to know for sure how this is going to work as I need only advice for the time being.
