Configuring VPN Security Associations Entering information on the Advanced tab 13-64 Configuring Virtual Private Networks 2. In the IPSEC Hashing Algorithms area, select an algorithm from the Available list of available hashing algorithms, and click the ==>> button to move it to the Accept list. You can have multiple algorithms in the Accept list. Use the Up and Down buttons to organize the algorithms according to your preference. The first algorithm that appears in the Accept list will be used. The Advanced tab defines some of the more arcane points of a VPN association. As a general rule only administrators that are highlyschooled in the nuts and bolts of VPN should modify the information on this tab. The information on this tab is only used with automatic key exchange (that is Authentication Method = Password, Certificate + Certificate Authority, or Single Certificate on the Authentication tab). The Advanced tab contains the following fields and buttons. Phase 1 (ISAKMP) Rekey data fields Hard Limits—Indicates how often the system must negotiate for new ISAKMP keys and how much ISAKMP traffic this phase can protect. The defaults are 3600 seconds (1 hour) and 0 (meaning no limit to the amount of traffic). Soft Percentage—Indicates how far in advance of the hard limit to begin negotiating for new keys. This makes sure you have some new keys on hand by the time the hard limit expires. P1 Crypto—Specifies the crypto algorithm to use during Phase 1. P1 Hash: Specifies the hash algorithm to use during Phase 1. P1 Oakley—Indicates the Diffie-Hellman group to use for the PFS derivation of ISAKMP keys. Force XAuth on Rekey—Select this option to force XAuth to be performed each time the phase 1 session is started or renegotiated. Phase 2 (IPSEC) Rekey data fields Hard Lifetimes—Indicates how often the system must negotiate for new IPsec keys and how much traffic it can encrypt. The defaults are 700 seconds and 0 (meaning no traffic limit). Soft Percentage—Indicates how far in advance of the hard limit to begin negotiating for new keys. This makes sure you have some new keys on hand by the time the hard limit expires.
Example VPN Scenarios Example VPN Scenarios Negotiate As Single Host—If this option is enabled it indicates that every possible combination of source and destination must establish a separate VPN association. Do not use this option unless directed to do so by Secure Computing Corporation. Forced Rekey—Forces the association to rekey when the limits are reached, even if no traffic has passed through the VPN since the last rekey. Important: SCC strongly recommends enabling the Forced Rekey option if you are using SafeNet SoftRemote and have XAUTH configured. Caution: Do not enable the Forced Rekey option if you have One-To-Many configured and are using static IP addresses for your VPNs. Doing so will cause all Sidewinder G2s in the cluster to attempt to instantiate the VPN at the same time, resulting in failure. PFS—(Perfect Forward Secrecy) If this option is enabled it ensures that the key material associated with each IPsec security association cannot be derived from the key material used to authenticate the remote peer during the ISAKMP negotiation. If a key is compromised by a hacker, the information available to that hacker is dependent on whether you select Identity or Key Only. — Identity: Indicates that a Phase 1 negotiation is performed for every Phase 2. This means the identity will not be revealed even if the key is compromised; only the data protected by that key will be accessible. The downside is that system performance may be hurt because of the many negotiations. — Key Only: Phase 1 negotiations are not performed for every Phase 2. This will increase performance but may allow access to the identity if the key is compromised. Oakley Group: Indicates the Diffie-Hellman group to use for the PFS derivation of IPsec keys. Available only if the PFS option is enabled. The following sections describe three typical VPN scenarios. Each scenario begins by describing a particular VPN requirement. It then explains how to implement the solution using the Admin Console. These scenarios assume the following: The VPN feature is licensed for your Sidewinder G2. The CMD server is enabled on the Sidewinder G2. (This server will be enabled by default.) Configuring Virtual Private Networks 13-65
