Normally, if any one of VPN peers wants to disconnect

 

 

 

the connection, it should follow a serial of packet

 

 

 

exchange procedure to inform each other. However, if the

 

 

 

remote peer disconnect without notice, Vigor router will

 

 

 

by no where to know this situation. To resolve this

 

 

 

dilemma, by continuously sending PING packets to the

 

 

 

remote host, the Vigor router can know the true existence

 

 

 

of this VPN connection and react accordingly. This is

 

 

 

independent of DPD (dead peer detection).

 

ISDN

Build ISDN LAN-to-LAN connection to remote network. You

 

should set up Link Type and identity like User Name and

 

Password for the authentication of remote server. You can

 

further set up Callback (CBCP) function below. This feature is

 

useful for i model only.

PPTP

Build a PPTP VPN connection to the server through the

 

Internet. You should set the identity like User Name and

 

Password below for the authentication of remote server.

IPSec Tunnel

Build an IPSec VPN connection to the server through Internet.

L2TP with …

Build a L2TP VPN connection through the Internet. You can

 

select to use L2TP alone or with IPSec. Select from below:

 

None: Do not apply the IPSec policy. Accordingly, the VPN

 

connection employed the L2TP without IPSec policy can be

 

viewed as one pure L2TP connection.

 

Nice to Have: Apply the IPSec policy first, if it is applicable

 

during negotiation. Otherwise, the dial-out VPN connection

 

becomes one pure L2TP connection.

 

Must: Specify the IPSec policy to be definitely applied on the

 

L2TP connection.

User Name

This field is applicable when you select ISDN, PPTP or L2TP

 

with or without IPSec policy above.

Password

This field is applicable when you select ISDN, PPTP or L2TP

 

with or without IPSec policy above.

PPP Authentication

This field is applicable when you select ISDN, PPTP or L2TP

 

with or without IPSec policy above. PAP/CHAP is the most

 

common selection due to wild compatibility.

VJ compression

This field is applicable when you select ISDN, PPTP or L2TP

 

with or without IPSec policy above. VJ Compression is used

 

for TCP/IP protocol header compression. Normally set to Yes

 

to improve bandwidth utilization.

IKE Authentication

This group of fields is applicable for IPSec Tunnels and L2TP

Method

with IPSec Policy.

 

Pre-SharedKey-Input 1-63 characters as pre-shared key.

 

Digital Signature (X.509) - Select one predefined in the

 

X.509 Peer ID Profiles.

IPSec Security Method

This group of fields is a must for IPSec Tunnels and L2TP

 

with IPSec Policy.

Medium

Authentication Header (AH) means data will be

 

authenticated, but not be encrypted. By default, this option is

 

active.
