Use Static Address Translation

If you use a notebook for work at the office, it is probable that you also bring it home to connect to the Internet and retrieve emails or surf the web. Since it is most likely that your office’s and your home’s broadband-sharing network subnets are differently configured, you would have to struggle with reconfiguring your TCP/IP settings each time you use the notebook in a different place. The router provides the Static Address Translation (SAT) feature to enable its users to bypass this hassle.

Let's say that the IP address of your notebook is set to 203.120.12.47 at the workplace but the router that is connecting your home network to the Internet, is using an IP address of 192.168.168.1. You have enabled SAT on your router and want to access the Internet without changing the IP address of the notebook as you have to use it at work again on the next day.

Since it is still set to the TCP/IP settings used in your office, the notebook will then try to contact the IP address of your office's gateway to the Internet. When the router finds that the notebook is trying to contact a device that lies in a different subnet from that of the home network, it would then inform the notebook that the gateway to the Internet is in fact itself (the router).

Once the notebook has been informed that the gateway to the Internet is the router, it will contact the latter (the router) to access the Internet, without any change to its TCP/IP settings required.

1.Under the HOME USER FEATURES command menu, click on Static Address Translation.

2.You may then choose to Enable or Disable Static Address Translation here, followed by clicking the Apply button. (Note: SAT is disabled by default)

Note: For SAT to function properly:

!1. The IP address of the notebook should belong to a different subnet from the LAN IP address of the router.

2.The <Default Gateway> in the TCP/IP settings of your notebook should NOT be left blank.
