Authentication
If a call is received, PPP authentication is carried out with the connection partner depend-
ing on the configuration, before the call is accepted. Your device needs the necessary data
for this, which you should enter here. First establish the type of authentication process that
should be performed, then enter a common password and two codes. You get this informa-
tion, for example, from your Internet Service Provider (ISP) or the system administrator at
your head office. If the data you entered on your device is the same as the caller's data, the
call is accepted. The call is rejected if the data is not the same.
Default Route
With a default route, all data is automatically forwarded to one connection if no other suit-
able route is available. If you set up access to the Internet, you must configure the route to
your Internet Service Provider (ISP) as a default route. If, for example, you configure a cor-
porate network connection, only enter the route to the head office or branch office as a de-
fault route if you do not configure Internet access over your device. If, for example, you
configure both Internet access and a corporate network connection, enter a default route to
the ISP and a network route to the head office. You can enter several default routes on
your device, but only one default route can be active at any one time. If you enter several
default routes, be aware of differing values for Metric.
Activating NAT
With Network Address Translation (NAT), you conceal your whole network to the outside
world behind one IP address. You should certainly do this for your connection to the Inter-
net Service Provider (ISP).
Only outgoing sessions are allowed initially if NAT is activated. To allow certain connec-
tions from outside to hosts within the LAN, these must be explicitly defined and admitted.
Connection Idle Timeout
The connection idle timeout is determined in order to clear the connection automatically if it
is not being used, i.e. if data is no longer being sent, to help you save costs where neces-
sary.
Block after Connection Failure
You use this function to set up a waiting time for outgoing connection attempts after which
your device's connection attempt is regarded as having failed.
