Remote access made simple with ELSA LANconfig and its wizards
For the configuration of individual access accounts, there is a wizard in ELSA LANconfig
which makes all required settings in the software for you and takes the peculiarities of
TCP/IP networks into account. Once you have started the wizard (automatically or by
clicking
Tools
왘
Setup Wizard ) select the entry 'Provide Dial-in access (RAS)'. The
wizard will now prompt you for the required data, including the network protocol in use.
Step by step: which settings do you configure on the router?
햲
First of all specify your own call number for incoming and outgoing calls in the
Router-interface-list (configuration area 'Communication', 'General' tab):
cd /Setup/WAN-module/Router-interface-list
set S0-1 123321 ON
When specifying several call numbers the first number is used for outgoing calls.
The 'Y connection' option is enabled in this instance so that simultaneous connections to
two different teleworkers are also possible.
햳
Remote access should also be possible without verification of the incoming call
number since field service employees at least sometimes will require access to the
company network from different locations. It is therefore not possible to assign call
number recognition to a layer which uses PPP. Check the values for the default layer
and set them to the required values if required:
cd /Setup/WAN-module/Layer-list
set DEFAULT trans PPP trans none HDLC64K
This ensures that every caller that is not entered in the name list is immediately
welcomed by PPP negotiation.
If the router determines that the remote station is calling via GSM, the
Trans
APPP Trans no V.110 9600
protocol settings will be used automatically for
the call establishment.
햴
For callback to GSM mobile telephones, a layer will be needed later that is set up
for connections using the V.110 protocol:
cd /Setup/WAN-module/Layer-list
set RAS_GSM Trans APPP Trans none
or
comp. V.110 9600
햵
The entry in the name list for each RAS remote station designating the remote
station, layer ('DEFAULT' or 'RAS_GSM') and the callback option 'Name' allows the
ELSA LANCOM to call back the computer of the field service employee. This forces
a protocol negotiation using PPP, the call number for callback remains blank in the
name list and can be specified by the field service employee himself. If a field staff
