Remote Management
By default, the Eicon 1550/1551 does not allow remote devices to access its
configuration interfaces via the external network. This feature can be enabled;
however, this does not affect traffic on the local LAN created by the Eicon 1550/1551. If
the local LAN is connected to other networks, these computers will continue to have
access to the Eicon 1550/1551, even if remote management is disabled. Consider the
following topology:
In the above example, all computers on the two LANs have access to the
Eicon 1550/1551 configuration interfaces. However, remote computer A is blocked as it
must go through the external network to access the Eicon 1550/1551.
Note: Remote security is implemented using IP filtering. In the web interface, expand the ‘IP’ section
and click ‘Filters’.
