VoIP gateway IP400 version 5.01
4.2.7 The remote maintenance facility in the standard
configuration
In the standard configuration, the
PPP
ISDN interface is configured to dial-up up
for remote maintenance. This allows the gateway to be configured remotely from
any PC with an ISDN card and a PPP remote data transmission programme (e.g.
Windows DUN).
The settings for this are configured in the logical interface PPP0, which you can
view and modify as desired under
IP Interfaces > PPP0 Interface
.
• Calls are answered on the
PPP
interface (
ISDN port
is
PPP
,
Allow
incoming calls
checkbox is ticked).
• Calls are accepted to every MSN (
Subscriber number
is empty).
• The calling party is assigned an IP address (
192.168.0.253
) (the
Assign
remote IP address
checkbox is ticked).
• Calls are accepted from all remote entities (
Check remote Number
is
blank).
• As
User
admin
is used and as
Password
ip400
.
• Reverse authentification does not take place (the fields under
Outgoing
calls
are blank).
• The called gateway itself is assigned the IP address
192.168.0.254
.
Tip
The standard setting for this is disabled. To activate the preconfigured remote
maintenance facility, uncheck the “Disable” option in the configuration applet
under
IP Interfaces > PPP0 Interface > Interface name and general
config
.
Tip
Under normal circumstances this IP address should not overlap with the
address of a device on the LAN. If however, there is a device on the network
with the IP address
192.168.0.254
, the gateway itself will not be able to
communicate with this device. This address is programmed permanently into
the gateway. This ensures that a gateway can always be addressed, under this
IP address, via the remote maintenance facility, regardless of which IP
address is set on the Ethernet interface of the gateway.
