Group 5: Uses a 1536-bit Diffie-Hellman prime modulus group.

Preshared Key:

The first key that supports IKE mechanism of both VPN gateway and VPN client host for negotiating further

 

security keys. The pre-shared key must be same on both VPN gateways and clients.

Remote ID:

The Type and the Value must be the same as the Type and the Value of the Local ID of the remote VPN

 

gateway.

Local ID:

The Type and the Value must be the same as the Type and the Value of the Remote ID of the remote VPN

 

gateway.

Extended Authentication:

With the xAuth feature, the VPN client (or initiator) needs to provide additional user information to remote VPN

 

server (or VPN gateway) for extended authentication. The VPN server would reject the connect request from

 

VPN clients because of the unknown user, even though the pre-shared key is correct. This function is suitable

 

to remote mobile VPN clients. You can configure a VPN rule with a pre-shared key for all remote users using,

 

but you can also designate only someone is permitted to establish VPN connection with VPN server.

xAuth - None:

Disables Extended Authentication (xAuth).

xAuth - Server Mode:

Select this checkbox if the device behaves as a VPN server, and will verify the legality of user information

 

from VPN client. The user information that is provided by VPN client needs to match to user information that

 

is in local user database of VPN server. You can press “XAUTH account” button to edit local user database.

 

Please note that only VPN clients with xAuth can establish VPN connection with the device if this checkbox

 

has been selected.
