translates from the source (internal) network. Each of the four fields must
be a number between 0 and 255. For instance, entering an IP address
network of 172.16.11.0 translates all addresses from 172.16.11.1 through
172.16.11.255.
Source Netmask Enter the subnet mask for the Source Network/Address . Each of the four
fields must be a number between 0 and 255.
Source Interface Enter the name of the network interface which contains the source network
(above).
Destination Interface Enter the name of the network interface which is the destination (external)
side of the network address translation. The public IP address on that
interface has already been defined in the
Ethernet or WiFi sections of the
configuration, or it might be assigned by the cellular provider as part of the
data services activation on that network. The interface names must be
entered such as
eth0 or ppp0 . See Understanding Network Interfaces on
page 22 for a description of the available interfaces on the ZyWAN-G9.
Masquerade
The normal setting for Masquerade is Yes, providing forwarding and
Network Address Translation between the two interfaces.
There may be rare cases where this should be set to
No , which retains the
internal forwarding of packets between the two interfaces, but disables the
network address translation.
Time Synchronization
Select the method of synchronizing the internal clock of the ZyWAN-G9. Available options are: None ,
GPS , and NTP . The GPS option allows the time to be acquired from the GPS receiver (if installed).
The NTP (Network Time Protocol) updates the clock using NTP protocol from a network server. The
following screen capture shows the
Table of NTP Servers table available if Time Synchronization is set
to NTP .
The following table lists the buttons available.
BUTTON
EXPLANATION
Insert Row#
Each of the table rows is numbered. In order to insert a row in the table,
enter a number in the box between 1 and one greater than the highest
number of rows. Then click the
Insert Row# button to insert a blank row.
This row needs to be filled in with all data required.
Delete Row#
In order to delete a row in the table, enter a number in the box between 1
and the highest number of rows. Then click the
Delete Row# button to
delete the row. Once a row is deleted, it cannot be restored without inserting
a row and entering the data again.
Note:
If the clock is not retained after loss of power, it may
either be that the battery link on the main circuit board is
not fitted or that the coin cell battery has failed and
needs to be replaced.
