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.

Setup > One-to-One NAT

One-to-One NAT

One-to-One NAT  Select Enable to use the One-to-One NAT function.

Private Range Begin  Enter the starting IP address of the internal IP address range. This is the IP address of the first device that

Public Range Begin  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 1.

Click Add to List, 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.
