Planning a VPN
When you set up a VPN, it is helpful to plan the network configuration and record the
configuration parameters on a worksheet:
To set up a VPN connection, you must configure each endpoint with specific identification and
connection information describing the other endpoint. You must configure the outbound VPN
settings on one end to match the inbound VPN settings on other end, and vice versa.
This set of configuration information defines a security association (SA) between the two VPN
endpoints. When planning your VPN, you must make a few choices first:
•
Will the local end be any device on the LAN, a portion of the local network (as defined by a
subnet or by a range of IP addresses), or a single PC?
•
Will the remote end be any device on the remote LAN, a portion of the remote network (as
defined by a subnet or by a range of IP addresses), or a single PC?
