Chapter 6. Administration of the Telecommuting Module
No.
The No. field determines the order of the lines. The order is important in deciding what
is logged and warned for. The Telecommuting Module uses the first line that matches the
configuration traffic.
Perhaps you want to configure the Telecommuting Module so that configuration traffic from
one specific computer is simply logged while traffic from the rest of that computer's network
is both logged and generates alarms.
The rules are used in the order in which they are listed, so if the network is listed first, all
configuration traffic from that network is both logged and generates alarms, including the
traffic from that individual computer. But if the individual computer is listed on a separate
line before the network, that line will be considered first and all configuration traffic from
that computer is only logged while the traffic from the rest of the computer's network is both
logged and generates alarms.
DNS Name Or Network Address
Enter the DNS name or IP address of the computer or network from which the Telecommut-
ing Module can be configured. Avoid allowing configuration from a network or computer on
the Internet or other insecure networks, or use HTTPS or IPsec to connect to the Telecom-
muting Module from these insecure networks.
Network address
Shows the network address of the DNS Name Or Network Address you entered in the
previous field.
Netmask/Bits
Netmask/Bits is the mask that will be used to specify the configuration computers. See
chapter 3 of the User Manual for instructions on writing the netmask. To limit access so that
only one computer can configure, use the netmask 255.255.255.255. You can also specify
the netmask as a number of bits, which in this case would be 32. To allow configuration
from an entire network, you must enter the network address under Network address, and
a netmask with a lower number here. To allow configuration from several computers or
networks, create several lines for the information.
Range
The Range shows all IP addresses from which the Telecommuting Module can be config-
ured. The range is calculated from the configuration under DNS Name Or Network Ad-
dress and Netmask/Bits. Check that the correct information was entered in the DNS Name
Or Network Address and Netmask/Bits fields.
Via IPsec Peer
Here, you can select an IPsec Peer from which this connection must be made. If an IPsec
peer is selected, you will only be able to configure the Telecommuting Module from this IP
address through an IPsec tunnel.
