Enterprise Multi-WAN VPN QoS Router
120
When users set this VPN tunnel to use any encryption and authentication mode, users
must set the parameter of this exchange password with that of the remote. Setting methods
include Auto (IKE) or Manual. To do the settings, select any one from the two options.
IKE Protocol
：
Click the shared key generated by IKE to encrypt and authenticate the remote user. If
PFS (Perfect Forward Secrecy) is enabled, the Phase 2 shared key generated during the IKE
coordination will conduct further encryption and authentication. When PFS is enabled,
hackers using brute force to capture the key will not be able to get the Phase 2 key in such
a short period of time.
Perfect Forward Secrecy:
When users check the PFS option, don't forget to
activate the PFS function of the VPN device and the VPN Client as well.
Phase 1/ Phase 2 DH Group:
This option allows users to select Diffie-Hellman
groups: Group 1/ Group 2/ Group 5.
Phase 1/ Phase 2 Encryption:
This option allows users to set this VPN tunnel to
use any encryption mode. Note that this parameter must be identical to that of the
remote encryption parameter: DES (64-bit encryption mode), 3DES (128-bit
encryption mode), AES (the standard of using security code to encrypt information).
It supports 128-bit, 192-bit, and 256-bit encryption keys.
