Using Internet Setup
In this field…
Do this…
Connect on
demand
Select this option if you do not want the dialup modem to be constantly
connected to the Internet. The modem will dial a connection only under
certain conditions.
This option is useful when configuring a dialup backup connection. For
information, see
Setting Up a Dialup Backup Connection
on page 92.
When no higher
priority connection
is available
Select this option to specify that the dialup modem should only dial a
connection if no other connection exists, and the NetDefend firewall is
not acting as a Backup appliance.
If another connection opens, the dialup modem will disconnect.
For information on configuring the appliance as a Backup or Master, see
Configuring High Availability
on page 119.
On outgoing
activity
Select this option to specify that the dialup modem should only dial a
connection if no other connection exists, and there is outgoing activity
(that is, packets need to be transmitted to the Internet).
If another connection opens, or if the connection times out, the dialup
modem will disconnect.
Idle timeout
Type the amount of time (in minutes) that the connection can remain idle.
Once this period of time has elapsed, the dialup modem will disconnect.
Obtain IP address
automatically
(using DHCP)
Clear this option if you do not want the NetDefend firewall to obtain an IP
address automatically using DHCP.
IP Address
Type the static IP address of your NetDefend firewall.
Subnet Mask
Select the subnet mask that applies to the static IP address of your
NetDefend firewall.
