MoRoS GPRS 2.1 PRO Functions
12.5.6 Configuring Routing
Routing is the core function of the MoRoS GPRS 2.1 PRO. Routing means that the
MoRoS GPRS 2.1 PRO routes incoming data packets according to certain rules de-
fined by you to certain network devices.
The routes determine whereto packets are forwarded. A network address and the
network mask are used to distinguish, whether a route is applied to an IP packet or
not. If a packet comes in, that has a destination with an existing route, the MoRoS
GPRS 2.1 PRO forwards the packet to the gateway address defined in the route.
Moreover, the MoRoS GPRS 2.1 PRO supports Network Address Translation. If NAT
is enabled, the MoRoS GPRS 2.1 PRO replaces the source address of the packets of
an outgoing connection with its own. The MoRoS GPRS 2.1 PRO 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 original source.
Configuration with the web interface
You can specify a default route. All incoming packets, which cannot be
assigned to a route, 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
operation 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
operation if the routed packets must not be changed.
In order to create a route, 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
GPRS 2.1 PRO switches incoming requests to the specified gateway for
this network.
Save your settings by clicking "OK".
In order to delete an existing route, check in the field "Existing routes" the
checkbox in "delete" in the line of the respective route. The route is de-
leted if you save the settings with "OK".
