IKEv2 Settings for an IPsec Template
Option Description
Template Name Type a name for the template (up to 16 characters).
Use Prefixed Template Select Custom , IKEv2 High Security , or IKEv2 Medium Security .
The setting items are different depending on the selected template.
Internet Key Exchange (IKE) IKE is a communication protocol that is used to exchange encryption
keys in order to carry out encrypted communication using IPsec. To
carry out encrypted communication for that time only, the encryption
algorithm that is necessary for IPsec is determined and the encryption
keys are shared. For IKE, the encryption keys are exchanged using the
Diffie-Hellman key exchange method, and encrypted communication
that is limited to IKE is carried out.
If you selected
Custom in Use Prefixed Template , select IKEv2 .
Authentication Type • Diffie-Hellman Group
This key exchange method allows secret keys to be securely
exchanged over an unprotected network. The Diffie-Hellman key
exchange method uses a discrete logarithm problem, not the
secret key, to send and receive open information that was
generated using a random number and the secret key.
Select
Group1 , Group2 , Group5 , or Group14 .
• Encryption
Select DES , 3DES , AES-CBC 128 , or AES-CBC 256 .
• Hash
Select MD5 , SHA1 , SHA256 , SHA384 or SHA512 .
• SA Lifetime
Specify the IKE SA lifetime.
Type the time (seconds) and number of kilobytes (KByte).
Encapsulating Security • Protocol
Select ESP .
ESP is a protocol for carrying out encrypted communication
using IPsec. ESP encrypts the payload (communicated
contents) and adds additional information. The IP packet
comprises the header and the encrypted payload, which follows
the header. In addition to the encrypted data, the IP packet also
includes information regarding the encryption method and
encryption key, the authentication data, and so on.
• Encryption
Select DES , 3DES , AES-CBC 128 , or AES-CBC 256 .
• Hash
Select 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.
