Currently we have a Vigor 3300 router that acts as our VPN server. At the moment we set up connections for home workers manually in the device.
What I would like to do is remove this extra step and instead allow them to use their Active Directory credentials to login to the VPN. I understand RADIUS is the way to do this. Unfortunately the manual for the Vigor is quite cryptic, although it give details on how to set up the unit itself I am unsure about how I set up the actual RADIUS server.
Can any one offer some generic advice on how to do this, or point to a resource on the internet that is idiot proof.
