Chapter 6. Basic Configuration
Policy For Ping To the Telecommuting Module
Here, you specify how the Telecommuting Module should reply to ping packets to its IP addresses. You can choose
between Never reply to ping, Only reply to ping from the same interface and Reply to ping to all IP addresses.
Only reply to ping from the same interface means that the ping request should originate from a network which is
directly connected to the pinged interface of the Telecommuting Module or from a network to which there exists a
static route from the pinged interface, or the request will be ignored.
Ping is a way of finding out whether a computer is working. See appendix D, Definitions of Terms, for further
information on ping.
Default Gateways
A Default Gateway is the IP address of a router that is used to contact the outside world. This IP address is usually
the firewall. Default Gateway must be an IP address from one of the Directly Connected Networks of the
Telecommuting Module’s interfaces. See appendix D, Definitions of Terms, for further description of
routers/gateways.
The Telecommuting Module must have at least one default gateway to work. You can enter more than one default
gateway. The Telecommuting Module will use one of them until it stops responding, and then switch to the next one.
DNS name or IP address
Enter the DNS name or IP address for the default gateway. If an interface will receive its IP address from a DHCP
server, the Telecommuting Module will get its default gateway from the server, and Default Gateway must be set to
"*".
IP address
Shows the IP address of the DNS name or IP address you entered in the previous field.
Gateway Reference Hosts
The gateway reference hosts are used by the Telecommuting Module to check if the gateways are alive. For each
reference host, test ping packets are sent, using the different gateways.
Reference hosts are only needed when multiple default gateways are used.
DNS name or IP address
Enter the DNS name or IP address for the reference host. The reference host must be located on the other side of the
default gateway.
