Planning Your VPN Using NSM Overview
NSM offers you maximum flexibility for creating a VPN. You can choose your topology, authentication level, and creation method. Because you have so many choices, it’s a good idea to determine what your needs are before you create the VPN so you can make the right decisions for your network.
These decisions include:
- VPN Topology—What do you want to connect? How many devices? How do you want these devices to communicate? Will you have users as VPN members?
- Data Protection—How much security do you need? Do you need encryption, authentication, or both? Is security more or less important than performance?
- Tunnel Type—Do you want an always-on connection or traffic-based connection?
- VPN Manager or Device-Level—How do you want to create the VPN? Maintain the VPN?
The following topics provide information to help you make these decisions.
