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.

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.
