VPN Policy Configuration for Auto Key Negotiation

An already defined IKE policy is required for VPN - Auto Policy configuration. From the VPN

Policies section of the main menu, you can navigate to the VPN - Auto Policy configuration menu.

Remote These parameters apply to the target remote FVS114, VPN gateway, or

VPN client.

Remote Identity Type Use this field to identify the remote FVS114. 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 FVS114 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 is the default

• 3DES is more secure

Authentication Algorithm If you enable Authentication Header (AH), this menu lets you to select from

these authentication algorithms:

• MD5 — the default

• SHA-1 — more secure

Authentication Method You may 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 (D-H) Group The DH Group setting determines the bit size used in the key exchange.

This must match the value used on the remote VPN gateway or client.

SA Life Time The amount of time in seconds before the Security Association expires;

over an hour (3600) is common.
