햳
Open a telnet session to the
ELSA LANCOM. Use the following IP address for this
purpose:
– '172.17.17.18', if you have not defined an IP address for the PPP client. The
ELSA
LANCOM automatically uses this address if no other address has been defined.
The calling PC then responds to the IP address '172.17.17.17'.
– Raise the IP address of the PC by one, if you have defined an address. For
example: If you have defined the IP address '10.0.200.123' for the PPP client, the
ELSA LANCOM will respond to '10.0.200.124'. Exception: If the digits '254' are
at the end of the IP address, the router responds to 'x.x.x.1'.
햴
You can configure the
ELSA LANCOM remotely just like all other devices.
Limiting remote configuration
The PPP connection of any other remote site to the router, of course, will only succeed if
the device answers every call with the corresponding PPP settings. This is the case using
the factory default settings because the default protocol (default layer) is set to PPP.
You may, however, want to change the default layer for LAN-to-LAN connections, for
example, to a different protocol after the first configuration run. Then the device will no
longer take calls on the dial-up connection using the PPP settings. The solution to this is
to agree upon a special calling number for configuration access. If the device receives a
call on this number, it will always use PPP, regardless of any other settings made on the
router. Only a specific user name which is automatically entered by the
ELSA LANconfig
program during call establishment will be accepted during the PPP negotiations.
햲
In the 'Management' configuration group select the 'Security' tab.
햳
In the 'Configuration access' field, choose whether the configuration is fully
accessible, read-only or not accessible from remote networks.
Alternatively, enter the following command during a telnet or terminal connection:
set /Setup/Config-module/Wan-config [on][read][off]
If you wish to block access to the router from the WAN entirely, set configuration access
from remote networks to 'denied'.
햴
As the calling number in the 'Configuration access' area, enter a MSN or EAZ of your
ISDN connection which is not used by the router, the
LANCAPI or the a/b ports.
Alternatively, enter the following command:
set /Setup/Config-module/Farconfig (EAZ-MSN) 123456
햵
You can protect the configuration of the device by assigning a password.
