Network Setup > Masquerading

Masquerading is a process which allows a whole network to hide behind one or several addresses preventing the

identification of your network topology from the outside. Masquerading enables the user to enter only one source network. All

services are automatically included in the transition. The translation takes place only if the packet is sent via the indicated

network interface. The address of this interface is used as the new source of the data packets.

On this screen you can select networks or network groups to be masked to selected network cards. Masquerading is

especially useful for connecting private networks to the Internet. It allows you to hide internal IP addresses and network

information from the outside network.

Masquerading

Select one of the networks already defined in the Networks menu. Select a network from each box (from

and to networks).

Add

Click the Add button. The Masqueraded network route displays below.

Edit or Delete a Route

Select Masqueraded network route from the lower box and click the Edit or Delete button. When deleting

a Masqueraded network route, the interface adapts accordingly.

Example

In this example, the sent packet does not contain any internal information. The reply to the request is

recognized by the RouteFinder and is passed on to the requesting computer.

Computer A with the address XY is inside a masked network within the RouteFinder.

It starts an HTTP request into the Internet. Computer A - and all computers in this network - use the only

official IP address. For all data packets that are to go into the Internet, the IP address of the sender is

exchanged for the IP address of the external network card.
