employees must be able to access the resources from any location across the world. The network infrastructure requirements for this purpose like VPN appliances and software needs to be identified. The management would like to know the different products which are available for achieving the solution and a detailed methodology which would include additional requirements like public ip addresses, changes to be made on the perimeter router for allowing the VPN traffic and other additional requirements to make the solution work.
