Description
The time interval before the SA (security association) expires. (It is
automatically reestablished as required.) While using a short time
period (or data amount) increases security, it also degrades
performance. It is common to use periods over an hour (3600 seconds)
for the SA life-time. This setting applies to both IKE and IPSec SAs.
• If this check box is selected, security is enhanced by ensuring that
the key is changed at regular intervals. Also, even if one key is
broken, subsequent keys are no easier to break. (Each key has no
relationship to the previous key.)
• This setting applies to both IKE and IPSec SAs. When configuring
the remote endpoint to match this setting, you might have to specify
the key group used. For this device, the key group is the same as the
DH Group setting in the IKE section.
Enter a unique name to identify this policy. This name is not supplied to
the remote VPN endpoint. It is used only to help you manage the
policies.
• The remote VPN endpoint must have this VPN gateway's address
entered as its remote VPN endpoint.
• If the remote endpoint has a dynamic IP address, select Dynamic IP
address. No address data input is required. You can set up multiple
remote dynamic IP policies, but only one such policy can be enabled
at a time. Otherwise, select an option (IP address or domain name)
and enter the address of the remote VPN endpoint to which you want
to connect.
• If you want to ensure that a connection is kept open, or, if that is not
possible, that it is quickly reestablished when disconnected, select
this check box.
• The ping IP address must be associated with the remote endpoint.
The remote LAN address must be used. This IP address will be
pinged periodically to generate traffic for the VPN tunnel. The remote
keep-alive IP address must be covered by the remote LAN IP range
and must correspond to a device that can respond to ping. The range
should be made as narrow as possible to meet this objective.
Enter the network mask.
• Enter the IP address for a single address, or the starting address for
an address range. A single address setting is used when you want to
make a single server on your LAN available to remote users. A range
must be an address range used on your LAN.
• Any. The remote VPN endpoint might be at any IP address.
