Select Custom, IKEv1 High Security or IKEv1 Medium Security. The setting items are different depending on the selected template. The default template differs depending on whether you chose Main or Aggressive for Negotiation Mode on the IPsec configuration screen. 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 IKEv1. • 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). • Protocol Select ESP, AH, or AH+ESP. 443
