Model FVL328 ProSafe High-Speed VPN Firewall Reference Manual Revision 2 Table 6-1. IKE Policy Configuration Fields Field Description Remote These parameters apply to the target remote FVL328 firewall, VPN gateway, or VPN client. Remote Identity Type Use this field to identify the remote FVL328. You can choose one of the following four options from the drop-down list: • By its Internet (WAN) port IP address. • By its Fully Qualified Domain Name (FQDN) - your domain name. • By a Fully Qualified User Name - your name, E-mail address, or other ID. • By DER ASN.1 DN - the binary DER encoding of your ASN.1 X.500 Distinguished Name. Remote Identity Data This field lets you identify the target remote FVL328 by name. IKE SA Parameters These parameters determine the properties of the IKE Security Association. Encryption Algorithm Choose the encryption algorithm for this IKE policy: • DES • 3DES is more secure and is the default Authentication Algorithm If you enable Authentication Headers (AH), this menu lets you select from these authentication algorithms: • MD5 -- less secure • SHA-1 - more secure (default) Authentication Method You can select Pre-Shared Key or RSA Signature. Pre-Shared Key Specify the key according to the requirements of the Authentication Algorithm you selected. • For MD5, the key length should be 16 bytes. • For SHA-1, the key length should be 20 bytes. RSA Signature RSA Signature requires a certificate. Diffie-Hellman (DH) Group The Diffie-Hellman groups are MODP Oakley Groups 1 and 2. The DH Group setting determines the size of the key used in the key exchange. This must match the value used on the remote VPN gateway or client. Select Group 1 (768 bit) or Group 2 (1024 bit). SA Life Time The amount of time in seconds before the Security Association expires; over an hour (3600) is common. Virtual Private Networking 6-5 May 2004, 202-10030-02
