Masquerading
If the user of the LT-4200 system has configured a data connection to a pc or service which has a preferred
way of access to the Internet, then masquerading may be of use. Masquerading allows the user to change
the IP address for services targeted by port forwarding. The source IP address will be changed to the IP
address of the LT-4200 LAN port. This forces the service to use the LT-4200 data service. An example of this
is illustrated in Figure 51. With masquerading active the connected PC can only see the LT-4200 LAN port IP
address and is forced to use it to access the IP data.
