Routing
Routing is the core function of the MoRoS ADSL 2.1 PRO. Routing means that
incoming data packets are routed to certain network devices according to certain
rules defined by you.
The routes determine whereto packets are forwarded. A net address and netmask
are used to distinguish, whether a route is applied to a IP packet or not. If a packet
comes in, that has a destination with an existing route, the device forwards the
packet to the gateway address defined in the route.
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.
Moreover, Network Address Translation is supported. If NAT is enabled, the device
replaces the source address of the packets of an outgoing connection with its own.
The device 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 via the web interface
In order to configure an IPv4 default route, check in the menu "LAN
(ext)" on the page "Routing" the checkbox "Set default route to gateway"
and enter the default gateway behind. The entry field is not visible in DSL
operation.
In order to configure an IPv6 default route, check the checkbox "Set IPv6
default route to gateway" and enter the default gateway behind. The
entry field is not visible in DSL operation.
In order to disable the NAT function for incoming packets, deactivate the
checkbox "Activate NAT for incoming IPv4 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 IPv4 packets". This may be useful
in LAN operation if the routed packets must not be changed.
In order to add a new route, enter in the section "Add new route" the
"net address", the associated "netmask" and a gateway into the
respective fields for IPv4 or IPv6. All fields must be completed that a new
route for the respective IP version is taken over into the table. Save the
route by clicking "OK".
In order to delete an existing route, check under "Existing routes" the
checkbox of the route(s) to be deleted.
Save your settings by clicking "OK".
