Once a data packet matches a rule, the data is acted upon
according to that rule and is not subjected to higher-numbered
rules.
4.
From the IFName drop-down list, select the interface on the
device to which this rule applies.
Typically, NAT rules are used for communication between your
LAN and the Internet. Because the device uses the WAN
interface (which may be named
ppp-0
or
eoa-0
) to connect your
LAN to your ISP, it is the usual IFName selection.
5. In the Local Address From field and Local Address To fields,
type the starting and ending IP addresses, respectively, of
the range of private address you want to be translated. Or,
type the same address in both fields to specify a single value.
To specify that data from all LAN addresses should be
translated, type 0 (zero) in each From field and 255 in each To
field.
If you have several non-sequential private addresses, you can
create an additional napt rule for each address.
These addresses should correspond to private addresses
already in use on your network (either assigned statically to
your PCs, or assigned dynamically using DHCP, as discussed
in the Quick Start).
6. In the Global Address From and Global Address To fields,
type the public IP address assigned to you by your ISP.
If you have multiple WAN interfaces, in both fields type the IP
address of the interface to which this rule applies. This rule will
not be enforced for data that arrives on other PPP interfaces.
If you have multiple WAN interfaces and want the rule to be
enforced on a range of them, type the starting and ending IP
addresses of the range.
