Vpn Policy - NETGEAR SRXN3205 - ProSafe Wireless-N VPN Firewall Wireless Router Reference Manual

IPSec Host: The router is authenticated by a remote gateway with a username and password
combination. In this mode, the router acts as a VPN Client of the remote gateway.

VPN Policy

You can create two types of VPN policies. When using the VPN Wizard to create a VPN policy,
only the Auto method is available.
• Manual. All settings (including the keys) for the VPN tunnel are manually input at each end
(both VPN Endpoints). No third party server or organization is involved.
• Auto. Some parameters for the VPN tunnel are generated automatically by using the IKE
(Internet Key Exchange) protocol to perform negotiations between the two VPN Endpoints
(the Local ID Endpoint and the Remote ID Endpoint).
In addition, a Certificate Authority (CA) can also be used to perform authentication (see
"Managing Certificates" on page
from the CA. For each certificate, there is both a public key and a private key. The public key is
freely distributed, and is used to encrypt data. The receiver then uses its private key to decrypt the
data (without the private key, decryption is impossible). The use of certificates for authentication
reduces the amount of data entry required on each VPN endpoint.
Managing VPN Policies
The VPN Policies screen allows you to add additional policies—either Auto or Manual—and to
manage the VPN policies already created. You can edit policies, enable or disable policies, or
delete them entirely. The rules for VPN policy use are:
1. Traffic covered by a policy will automatically be sent via a VPN tunnel.
2. When traffic is covered by two or more policies, the first matching policy will be used. (In this
situation, the order of the policies is important. However, if you have only one policy for each
remote VPN Endpoint, then the policy order is not important.)
3. The VPN tunnel is created according to the parameters in the SA (Security Association).
4. The remote VPN Endpoint must have a matching SA, or it will refuse the connection.
VPN Policy Table
Only one Client Policy may configured at a time (noted by an "*" next to the policy name). The
Policy Table contains the following fields:
• ! (Status). Indicates whether the policy is enabled (green circle) or disabled (grey circle). To
Enable or Disable a Policy, check the radio box adjacent to the circle and click Enable or
Disable, as required.
