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 access point 

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 access point 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 access point 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 (Access Point).  

 

 

For SAT to function properly: 
1.  The IP address of the notebook should belong to a 

different subnet from the LAN IP address of your 

access point. 

 

2.  The <Default Gateway> in the TCP/IP settings of your 

notebook should NOT be left blank.
