12.2.5 Configuring Routing
Routing is the core function of the MoRoS LAN PRO 2.0. Routing means that the MoRoS
LAN PRO 2.0 routes incoming data packets according to certain rules defined by you to
certain network devices.
The routing rules determine whereto connection requests are forwarded. A network ad-
dress and the network mask are used to distinguish, whether a rule is applied to a packet
of the request or not. If a packet comes in, that has a destination with an existing rule,
the MoRoS LAN PRO 2.0 forwards the packet to the gateway address defined in the rule.
Moreover, MoRoS LAN PRO 2.0 supports Network Address Translation. If NAT is enabled
and a "Default Route" exists, the MoRoS LAN PRO 2.0 replaces the source address of the
packets of an outgoing connection with its own. MoRoS LAN PRO 2.0 stores the actual
source address in its NAT table. If it receives a reply packet of the remote terminal of this
connection, it replaces the destination address of the packet with the address of the ori-
ginal source.
Configuration with the web interface
In order to
create
a
route
or a routing rule, enter in the "LAN (ext)" menu on
the "Routing" page in the field "Add new route" the net address, the netmask
address belonging to it, and a gateway into the respective entry fields. The
MoRoS LAN PRO 2.0 switches incoming requests to the specified gateway for
this network.
You can specify a
default route . All incoming packets, which cannot be as-
signed to a rule, are sent to this gateway. If you have connected a DSL modem
to the LAN ext interface, you can set the default route to the DSL modem. For
this, activate the checkbox "Set default route to gateway". The following entry
field is invisible in DSL operation.
In order to
disable the NAT function for incoming packets , deactivate the
checkbox "Activate NAT for incoming packets". This may be useful in LAN op-
eration if the routed packets must not be changed.
In order to
disable the NAT function for outgoing packets , deactivate the
checkbox "Activate NAT for outgoing packets". This may be useful in LAN op-
eration if the routed packets must not be changed.
Save your settings by clicking "OK".
In order to delete an existing route , activate in the field "Existing routes" the
checkbox in "delete" in the line of the respective route. The route is deleted if
you save the settings with "OK".
