Setup > One-to-One NAT
One-to-One NAT (Network Address Translation) creates
a relationship that maps valid external IP addresses to
internal IP addresses hidden by NAT. A device with an
internal IP address may be accessed at the corresponding
external valid IP address.
To create this relationship, define internal and external
IP address ranges of equal length. Once the relationship
is defined, the device with the first internal IP address is
accessible at the first IP address in the external IP address
range, and so forth.
For example, you have a Local Area Network (LAN) for which
the ISP has assigned the IP address range of 209.19.28.16
to 209.19.28.31, with 209.19.28.16 used as the Wide Area
Network (WAN) or NAT public IP address of the Router.
The address range of 192.168.168.1 to 192.168.168.255 is
used for the devices on the LAN. With One-to-One NAT,
the devices with the internal IP addresses of 192.168.168.2
to 192.168.168.15 may be accessed at the corresponding
external IP addresses.
NOTE:
The Router's WAN IP address should not
be included in the range you specify.

NAT function.
Prvate Range Begn Enter the starting IP address of the
internal IP address range. This is the IP address of the first
device that
Publc Range Begn
Enter the starting IP address of the
public IP address range. This IP address is provided by the
ISP. (Do not include the Router's WAN IP Address.)
Range Length
Enter the number of IP addresses in the
range. The range length cannot exceed the number of
valid IP addresses. To map a single address, enter .
Click Add to Lst, and configure as many entries as you
would like, up to a maximum of 64. To delete an entry,
select it and click Delete selected range.
NOTE: One-to-One NAT affects how the firewall
functions work. Access to LAN devices from the
Internet is allowed unless access rules are set.

Setup > MAC Clone
Some ISPs require that you register a MAC address, which
is a 12-digit code assigned to a unique piece of hardware
for identification. The MAC Clone feature "clones" your
network adapter's MAC address onto the Router, so you
don't have to call your ISP to change the registered MAC
address to the Router's MAC address.
For the WAN port, you can assign or clone a MAC address.
