Port Forwarding
This lists the fixed rules for port forwarding.
With port forwarding the following takes place: the header of
incoming data packets from the external network which are
intended for the external IP address (or one of the external IP
addresses) of the SINAUT MD740-1 and for a particular port of the
SINAUT MD740-1 are rewritten in such a way that they are
forwarded to the internal network to a particular computer and to a
particular port of this computer. That means that the IP address
and port number in the headers of incoming data packets are
changed.
This method is also called Destination NAT.
