Configuring a Periodical DSL Connection Establishment
The EBW-E100 can establish and terminate the previously configured DSL
connection time-controlled. The DSL connection is established and terminated daily
at a certain time.
This function initiates individual events, regardless whether other times have
already been defined for the connection termination. Example: If you already
configure a daily connection termination at 14:00 and a daily connection
establishment at 16:00, other settings and events can also initiate a connection
establishment within this period, e.g. a packet, that complies with the dialling filter.
The connection is also terminated, if the configured "Idle time" has expired, for
example.
Configuration via web interface (menu "LAN (ext)", page "DSL")
In order to establish a daily connection at a certain time, check the
checkbox "Connect automatically once a day at" and enter a time for the
connection setup into the entry fields for hours and minutes.
In order to terminate a daily connection at a certain time, check the
checkbox "Disconnect automatically once a day at" and enter a time for
the disconnection into the entry fields for hours and minutes.
Save your settings by clicking "OK".
12.2.5
Routing
Routing is the core function of the EBW-E100. 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.
Due to the "stateful firewall" it is possible that changes to these
functions will not become effective immediately. This may happen if
connections or connection attempts have already been made.
