DNS server
This function is only supported by the DSL firmware.
The router's DNS server functions allow you to set up links between IP
addresses and names of computers or networks. The correct route can be
directly assigned in the event of queries for known computer names.
The DNS server can also serve as an effective filter for the users in your local
network. Access to specified domains can be denied to individual computers
or complete networks.
Routing: Line connection and management
The router checks all data on the network to determine whether they have to
be sent to another network or computer. If data transfer is necessary, the
router establishes the connection itself and closes the connection once the
transfer is complete. Any partly used call charge units are used up fully if call
charge information is transmitted during the connection.
To reduce transfer costs, the router offers various filter options depending on
the mode of operation. These filters can be used to exclude data from being
tranmitted to all or part of the network. Data that belongs to specific services
(e.g. printing services) can also be excluded from transfer.
NetBIOS proxy
ELSA routers offer a special feature for the interconnection of Microsoft
peer-to-peer networks. With the integrated routing of IP NetBIOS packets,
the linking of Windows networks becomes child's play. The remote stations
relevant for the exchange of data are entered in a list to ensure that not every
NetBIOS packet results in the establishment of a connection.
As a NetBIOS proxy, the router answers the queries for known workstations
locally to prevent unnecessary connections from being established.
Accounting
Most data transfers through the ELSA router take place via dial-up connec-
tions, where the charges are calculated based on the online time, or via static
connections, where the charges are calculated based on the transferred data
volume. Only a small portion of users use true leased-line connections with
flat-rate charging.
For many users it is important to determine which of the immediate LAN com-
puters use the connection to the router and what charges they incur.
