Option Description
• Hash
Select None, MD5, SHA1, SHA256, SHA384 or SHA512.
• SA Lifetime
Specify the IKE SA lifetime.
Type the time (seconds) and number of kilobytes (KByte).
• Encapsulation Mode
Select Transport or Tunnel.
• Remote Router IP-Address
Type the IP address (IPv4 or IPv6) of the remote router. Enter this
information only when the Tunnel mode is selected.
SA (Security Association) is an encrypted communication
method using IPsec or IPv6 that exchanges and shares
information, such as the encryption method and encryption key,
in order to establish a secure communication channel before
communication begins. SA may also refer to a virtual encrypted
communication channel that has been established. The SA
used for IPsec establishes the encryption method, exchanges
the keys, and carries out mutual authentication according to the
IKE (Internet Key Exchange) standard procedure. In addition,
the SA is updated periodically.
Perfect Forward Secrecy (PFS)
PFS does not derive keys from previous keys that were used to encrypt
messages. In addition, if a key that is used to encrypt a message was
derived from a parent key, that parent key is not used to derive other
keys. Therefore, even if a key is compromised, the damage will be
limited only to the messages that were encrypted using that key.
Select Enabled or Disabled.
Authentication Method Select the authentication method. Select Pre-Shared Key or
Certificates.
Pre-Shared Key When encrypting communication, the encryption key is exchanged and
shared beforehand using another channel.
If you selected Pre-Shared Key for the Authentication Method, type
the Pre-Shared Key (up to 32 characters).
• Local/ID Type/ID
Select the sender's ID type, and then type the ID.
Select IPv4 Address, IPv6 Address, FQDN, E-mail Address, or
Certificate for the type.
If you select Certificate, type the common name of the certificate
in the ID field.
• Remote/ID Type/ID
Select the recipient's ID type, and then type the ID.
Select IPv4 Address, IPv6 Address, FQDN, E-mail Address, or
Certificate for the type.
If you select Certificate, type the common name of the certificate
in the ID field.
Certificate
If you selected Certificates for Authentication Method, select the
certificate.
You can select only the certificates that were created using the
Certificate page of Web Based Management's Security
configuration screen.
