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.
The following table lists the fields available in the
Nat Table
if
Enable NAT
is set to
Yes
.
FIELD EXPLANATION
Source Network /
Address
Enter the numeric IP address, or range of addresses, which the
ZyWAN 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 21 for a description of the available
interfaces on the ZyWAN.
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.
