Netgear FVS318 FVS318v3 Reference Manual - Page 102

Reference Manual for the ProSafe VPN Firewall FVS318v3 Each CA has its own certificate. The certificates of a CA are added to the FVS318v3 and then can be used to form IKE policies for the user. Once a CA certificate is added to the FVS318v3 and a certificate is created for a user, the corresponding IKE policy is added to the FVS318v3. Whenever the user tries to send traffic through the FVS318v3, the certificates are used in place of pre-shared keys during initial key exchange as the authentication and key generation mechanism. Once the keys are established and the tunnel is set up the connection proceeds according to the VPN policy. Certificate Revocation List (CRL) Each Certification Authority (CA) maintains a list of the revoked certificates. The list of these revoked certificates is known as the Certificate Revocation List (CRL). Whenever an IKE policy receives the certificate from a peer, it checks for this certificate in the CRL on the FVS318v3 obtained from the corresponding CA. If the certificate is not present in the CRL it means that the certificate is not revoked. IKE can then use this certificate for authentication. If the certificate is present in the CRL it means that the certificate is revoked, and the IKE will not authenticate the client. You must manually update the FVS318v3 CRL regularly in order for the CA-based authentication process to remain valid. Walk-Through of Configuration Scenarios on the FVS318v3 There are a variety of configurations you might implement with the FVS318v3. The scenarios listed below illustrate typical configurations you might use in your organization. In order to help make it easier to set up an IPsec system, the following two scenarios are provided. These scenarios were developed by the VPN Consortium (http://www.vpnc.org). The goal is to make it easier to get the systems from different vendors to interoperate. NETGEAR is providing you with both of these scenarios in the following two formats: • VPN Consortium Scenarios without any product implementation details • VPN Consortium Scenarios based on the FVS318v3 User Interface The purpose of providing these two versions of the same scenarios is to help you determine where the two vendors use different vocabulary. Seeing the examples presented in these different ways will reveal how systems from different vendors do the same thing. 6-14 January 2005 Advanced Virtual Private Networking
