SA

To display: [Utility][Administrator][Network][TCP/IP Setting][IPsec][IPsec Setting][SA]

Configure SA (Security Association) required for encrypted communication. Up to 10 groups can be registered for the SA.

Setting

Description

[Name]

Enter the SA name (using 1 to 10 characters, excluding ").

[Encapsulation Mode]

Select the IPsec operation mode (default: [Transport]).

[Security Protocol]

Select a security protocol.

[Key Exchange Method]

Select the key replacement method to securely create a common key used to encrypt communications (default: [IKEv1]).

[Tunnel End Point]

If [tunnel] is selected in [Encapsulation Mode], enter the IP address of the IPsec gateway that is used as a peer.

[Lifetime After Establishing SA]

Enter the lifetime of a common key used to encrypt communications (default: [3600] sec.).

[IKE Setting]

Configure IKE settings used for this SA. This is required when [IKEv1] or [IKEv2] is selected in [Key Exchange Method].

  • [Authentication Method]: Select the authentication method.

  • [Local Authentication Method]: Select the authentication method of this machine when [IKEv2] is selected in [Key Exchange Method].

  • [Peer Authentication Method]: Select the peer authentication method when [IKEv2] is selected in [Key Exchange Method].

  • [ESN]: When applying the 64-bit extended sequence number, set this option to ON.

  • [Replay Detection]: When enabling replay defense, set this option to ON.

  • [ESP Encryption Algorithm]: If you select [ESP] for [Security Protocol], configure the ESP encryption algorithm.

  • [ESP Authentication Algorithm]: If you select [ESP] for [Security Protocol], configure the ESP authentication algorithm.

  • [AH Authentication Algorithm]: If you select [AH] for [Security Protocol], configure the AH authentication algorithm.

  • [Perfect Forward-Secrecy]: When increasing the IKE intensity, set this option to ON. Setting to ON increases the time spent for communication.
