Option Description
• 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,
Certificates, EAP - MD5, or EAP - MS-CHAPv2.
EAP is an authentication protocol that is an extension of PPP.
By using EAP with IEEE802.1x, a different key is used for user
authentication during each session.
The following settings are necessary only when EAP - MD5 or
EAP - MS-CHAPv2 is selected in Authentication Method:
• Mode
Select Server-Mode or Client-Mode.
• Certificate
Select the certificate.
• User Name
Type the user name (up to 32 characters).
• Password
Type the password (up to 32 characters). The password
must be entered two times for confirmation.
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.
