Restricted Management Access - Hirschmann RS20 Reference Manual

Security
2.4 Restricted Management
Access
This dialog allows you to differentiate (restrict) the management access to
the device based on IP address ranges and individual management services.
When you activate this function, you can only use the specified IP address
ranges to access the management services activated for these address
ranges. The device rejects other requests. You can create up to 16 entries in
the list, permit or forbid specific management access for each address range,
and activate or deactivate the individual entries separately.
The following management services support restricted management access:
http
snmp
telnet
Note: The CLI access via the V.24 interface is excluded from the function
and cannot be restricted.
Note: You require the http service to start the Web-based interface in a
browser.
Afterwards, you require the snmp service to access the device with the Web-
based interface. When you start the Web-based interface outside the
browser, you only require snmp.
In the default setting, the restricted management access is deactivated. In
this case, anyone with the correct administrator logon data has access to all
management services.
If you have activated the function, and if there is at least one active entry
whose IP address range matches the request and for which the requested
management service is allowed, the device processes the request.
Otherwise the device rejects it.
