For forwarding network communication through a router, it is necessary to note
that corresponding routing entries must be provided not only for the router, but
also for the respective endpoints of the communication. The routing entries of the
endpoints must ensure that the desired network data packets are sent via the
router, both when the connection is established and with the replies.
Host route example:
A host route is a route to an individual host. In the following example, a route to a
host with IP address 192.168.1.2 is to be specified. The route passes through a
gateway that can be reached via address 10.0.1.3. To configure a host route to
the destination host on a controller connected to the gateway, the following
settings must be made:
Destination Address: 192.168.1.2
Destination Mask:
Gateway Address:
Gateway Metric
Network route example:
A network route is a route to a subnet, which can contain multiple hosts. In the
following example, a route to a subnet should be specified with network address
192.168.1.0. The route passes through a gateway that can be reached via
address 10.0.1.3. To configure a network route to the destination network on a
controller connected to the gateway, the following settings must be made:
Destination Address: 192.168.1.0
Destination Mask:
Gateway Address:
Gateway Metric
Besides configuration of static routes, the controller also supports IP
masquerading. This can be enabled for selected network interfaces of the
controller. Network data packets that depart the controller through a network
interface for which IP masquerading has been enabled are given the IP address
of the network interface as their sender address. If network data packets are
forwarded through the controller, the network behind the controller is
encapsulated under a single address.
Furthermore, the controller permits configuration of port forwarding entries. For
port forwarding, the destination address and, if relevant, destination port of a
network data packet that arrived at the controller via a previously configured
network interface are overwritten. This makes it possible to forward network data
packets through the controller to other addresses and ports. Forwarding can be
configured for the TCP or UDP protocols.
