7. VPN Configuration
Overview
Virtual Private Network (VPN) is a connection between two end points. It allows private data
to be sent securely over a public network, such as Internet. VPN establishes a private
network that can send data securely between two networks by creating a “tunnel”. A VPN
tunnel connects the two PCs or networks
Note:
The SP880B VPN Router uses industry standard VPN protocol. However, due to
variations in how manufactures interpret these standards, many VPN products are not
interoperable. Although the SP880B VPN Router can interoperate with many other VPN
products, it is not possible for SP880B VPN Router to provide specific technical support for
every other product.
Planning the VPN:
When planning your VPN, you must make sure of the following items first.
1.
If the remote end was a network, the two-endpoint network must have different LAN IP
address ranges. If the remote endpoint is a single PC running a VPN client, its
destination address must be a single IP address, with subnet mask of
255.255.255.255
2.
If you will be using the Internet Key Exchange (IKE) setup, or Manual Key, in which you
must specify each phase of the connection.
3.
At least one side must have a fixed IP address. The other side with a dynamic IP
address must always be the initiator of the connection.
4.
The encryption level you are planning to use (DES or 3DES)?
