This name is not supplied to the remote VPN endpoint. It is used only to help you
manage the policies.
•
From the Address Type list, select Fully Qualified Domain Name, Dynamic IP
Address or Fixed IP Address.
You can set up multiple remote dynamic IP policies, but only one policy can be
enabled at a time.
•
If you want to ensure that a connection is kept open, or, if that is not possible, it is
quickly reestablished when disconnected, select the IKE Keep Alive check box and
fill in the Ping IP Address field.
The ping IP address has to be associated with the remote endpoint. Either the WAN
or a LAN address can be used; a LAN address is preferable. This IP address is
pinged to generate some traffic for the VPN tunnel.
5.
Specify the Local LAN settings:
•
From the IP Address list, select Subnet address, Single address, or Range
address.
•
Fill in the Single/Start IP Address field.
•
If you are specifying a range, fill in the Finish IP Address field.
This range must be an address range used on your LAN. For a single IP address, do
not fill in the Finish IP Address field.
The remote VPN endpoint must have these IP addresses entered as its remote
addresses.
6.
Specify the Remote LAN settings.
•
From the IP Address list, select Single PC -no Subnet, Single address, Range
address, or Subnet address.
If there is no LAN (only a single computer) at the remote endpoint, select the Single
PC -no Subnet option. The Single address option is typically used to access a server
on the remote LAN.
•
If you want to specify a range, fill in the Finish IP Address field.
This range must be an address range used on the remote LAN.
•
Fill in the Subnet Mask field.
The remote VPN endpoint must have these IP addresses entered as its local addresses.
7.
Specify the IKE settings:
•
From the Direction list, select either Responder only or Initiator and Responder.
The modem router uses this setting to determine if the IKE policy matches the current
traffic. With the Responder only setting, incoming connections are allowed and
outgoing connections are blocked. With the Initiator and Responder setting, both
incoming and outgoing connections are allowed.
•
Ensure that the remote VPN endpoint is set to use Main Mode.
