MLR 3G 2.0
Function Overview
HTTP and HTTPS proxy with URL filter
The proxy is used to limit the access to web addresses for applications in
the local network of the MLR 3G 2.0, and to avoid connection timeouts.
The MLR 3G 2.0 supports the HTTP and HTTPS protocols. The proxy of the
MLR 3G 2.0 maintains connections during the connection setup of the
communication device to prevent a premature timeout. The proxy will not
work as a cache for frequently accessed websites
Log files
The system messages of the MLR 3G 2.0 can be downloaded as text files
via the web interface.
Downloadable configuration files
The configuration of the MLR 3G 2.0 can be downloaded as binary or ASCII
file. The file can be used as backup copy to configure the MLR 3G 2.0 after
a factory reset, or for convenient loading of the same configuration into a
different MLR 3G 2.0. The ASCII configuration file can be edited and offers
a comfortable option for an alternative configuration.
Firmware update via web interface
The firmware of the MLR 3G 2.0 can be updated via the web interface. An
update can be performed locally or remotely.
Automatic daily update
The MLR 3G 2.0 allows a daily automatic update of firmware files, configu-
ration files (binary and ASCII) or sandbox image files that are provided ac-
cordingly on a server.
An optional, redundant communication device may be connected.
You can connect a second INSYS communication device via the serial inter-
face at the MLR 3G 2.0, to secure the dial-out and dial-in communication
through redundancy and to increase the availability.
Freely programmable sandbox
The MLR 3G 2.0 provides a freely programmable sandbox. The sandbox is a
kind of a virtual machine, which runs on the MLR 3G 2.0 and allows to start
programs, collect data and offer services in the sandbox, which do not ex-
ist in the actual system.
Debugging tools for analysing network connections
The MLR 3G 2.0 offers several tools for analysing problems with network
connections. Ping packets can be sent, routes of IP packets can be traced,
DNS information can be queried and network packets can be recorded
with this.
