NAT
Network Address Translation (NAT) provides a level of security by hiding the private IP addresses of your LAN behind the single public IP address of your router. All connections pass through the router and are translated by NAT. Network addresses on inbound traffic are translated from public to private IP addresses; while addresses on outbound traffic are translated from private IP addresses to the router’s public IP address.
1.To configure NAT, click NAT on the left navigation pane of the Router Information page. This displays the NAT Settings page. (You can also view the current inbound NAT settings for each protocol in the Current Inbound NAT Setting table.)
2.In the Outbound NAT Setting section of this page, select Enable or Disable to enable or disable NAT for communications from your LAN to the Wide Area Network (WAN).
3.Click Apply.
4.In the NAT Passthrough section of this page, select Enable or Disable to specify whether or not multiple VPN clients are allowed. Enabled, multiple VPN clients are allowed; disabled, only a single VPN client is allowed.
5.Click Apply.
6.On the Wan side of the Inbound NAT Setting section on this page, do one of the following:
•Select the network service you are configuring from the Service
•For Advanced Setup, select a protocol from the Protocol
7.On the Local Machine side of the Inbound NAT Setting section on this page, enter the IP address of the local machine in IP Address.
8.Do one of the following to enter port Information for the selected service:
•Click Add next to Default Port # to use the default port for the specified service.
•Enter the port number on the local machine you want the specified service to use in Port #, and click Add. Leave this field blank if you want the local machine to use the same port number as the WAN.
