10/100 8-Port VPN Router

Consider a LAN for which the ISP has assigned the IP addresses range from 209.19.28.16 to 209.19.28.31, with

209.19.28.16 used as the Router’s WAN IP (NAT Public) Address. The address range of 192.168.168.1 to

192.168.168.255 is used for the machines on the LAN. Typically, only machines that have been designated as

Public LAN Servers will be accessible from the Internet. However, with One-to-One NAT, the machines with the

internal IP addresses of 192.168.168.2 to 192.168.168.15 may be accessed at the corresponding external IP

address.

Note: The Router’s WAN IP (NAT Public) Address may not be included in a range.

One-to-One NAT: Enable: If you check the box, you will enable One-to-One NAT.

Private Range Begin: Enter the beginning IP address of the private address range being mapped in the Private

Range Begin field. This will be the IP address of the first machine being made accessible from the Internet.

Public Range Begin: Enter the beginning IP address of the public address range being mapped in the Public

Range Begin field. This address will be assigned by the ISP. The Router’s WAN IP (NAT Public) Address cannot be

included in the range.

Range Length: Enter the number of IP addresses for the range. The range length may not exceed the number of

valid IP address. Up to 64 ranges may be added. To map a single address, use a Range Length of 1.

Note: One-to-One NAT does not change the way the firewall functions work. Access to machines on the LAN from

the Internet will not be allowed unless Network Access Rules are set, or Authenticated User sessions are

established. You can click Add to List button or Delete selected range.

Click the Save Settings button to save the settings or click the Cancel Changes button to undo your changes.

Setup Tab - MAC Clone

Some ISPs require that you register a MAC address. This feature “clones” your network adapter's MAC address

onto the Router, and prevents you from having to call your ISP to change the registered MAC address to the

Router's MAC address. The Router's MAC address is a 12-digit code assigned to a unique piece of hardware for

identification. See Figure 6-17.

Input the MAC Address in the User Defined WAN1 or WAN2 MAC Address field or select MAC Address from this

PC.

Click Save Settings to save the MAC Cloning settings or click the Cancel Changes button to undo your changes.
