IPsec Protocols (Manual Keys)

Items on the IPsec Protocols page are described in the following table.

NOTE: You cannot use IPv4 address ranges with manual keys. Instead, use a specific IP address.

To use manual keys for key negotiation, use the following steps:

1.Specify IPsec protocol encryption and authentication methods to use for security associations (SA) in this rule. Configuration of manual keys depends on your selections.

2.Click OK, and then configure the manual keys for this template.

Table 5-14IPsec Protocols (Manual Keys) page

Item

Description

 

 

Encapsulation Type

Specify how the selected IPsec protocols (ESP or AH) are encapsulated:

 

● Transport (default): Only the user data in each IP packet is protected, the IP

 

packet header is not protected.

 

● Tunnel: All packet fields are protected, including the IP packet header.

 

 

Cryptographic Parameters

Set the encryption method/strength and the authentication methods used:

 

● ESP IPsec encapsulating security payload (ESP) protocol for IP packets. ESP

 

headers are inserted in packets to ensure privacy and integrity of packet contents.

 

Select among the supported encryption methods/strengths and authentication

 

methods to be used for data protection.

 

● AH IPsec authentication header (AH) protocol for IP packets. AH headers are

 

inserted in packets to protect integrity of packet contents through cryptographic

 

checksums. Select among the supported authentication methods.

 

CAUTION: IPsec AH might not function properly in environments that use

 

network address translation (NAT).

 

NOTE: For manual keys, you can select only one authentication method. You cannot

 

use ESP authentication if AH is enabled. If you enable ESP and AH, you must select

 

an AH authentication method.

 

 

Manual Keys

Items on the Manual Keys page are described in the following table. Use this page to configure encryption keys and Security Associations (SA) manually. Because the applicable hosts are also manually configured, authentication and dynamic key generation are not needed.

Table 5-15Manual Keys page

Item

Description

 

 

SPI Format

Use hexadecimal or decimal values to specify SPI values.

 

 

ESP SPI

(ESP SPI fields are listed if ESP is enabled on the IPsec Protocols page.) A 32-bit

 

field in an ESP header used to identify the IPsec security association (SA).

 

In Value for an SA to use for packets received by the device.

 

Out Value for an SA to use for packets sent by the device.
