MLR 3G 2.0
Function Overview
PPP Leased line operation
The MLR 3G 2.0 can establish and maintain a permanent connection via a
"dial-up line". This makes it possible to communicate with a network via a
dial-up connection such as a "leased line".
Periodic PPP connection setup
The MLR 3G 2.0 can establish and terminate a PPP connection time-
controlled. Fixed times can be set for the connection setup and termina-
tion.
OpenVPN
The MLR 3G 2.0 can be used as OpenVPN server or client. This enables ma-
chines to establish a safe connection to the LAN behind the MLR 3G 2.0
from the outside via an unsafe network. Prerequisite for this is that the
device can be accessed via a packet-switched connection (public IP ad-
dress) or a CSD connection is maintained permanently. The MLR 3G 2.0 can
also connect an entire LAN interception-proof and interference-proof via
an unsafe Internet connection through a VPN tunnel to another network
(e.g. the company network). The MLR 3G 2.0 can connect to an OpenVPN
server as client for this. The authentication when connecting to an
OpenVPN server via a static key, a certificate with user name and pass-
word, or just a certificate is supported with this. The MLR 3G 2.0 can also
establish an OpenVPN connection without authentication.
PPTP
The MLR 3G 2.0 can be used as PPTP server or client. This enables machines
to establish a safe connection to the LAN behind the MLR 3G 2.0 from the
outside via an unsafe network. Prerequisite for this is that the device can
be accessed via a packet-switched connection (public IP address) or a CSD
connection is maintained permanently. The MLR 3G 2.0 can also connect
an entire LAN interception-proof and interference-proof via an unsafe
Internet connection through a VPN tunnel to another network (e.g. the
company network). The MLR 3G 2.0 can connect to a PPTP server as client
for this.
IPsec protocol
The MLR 3G 2.0 can connect two subnets via an insecure internet connec-
tion tap- and interference-proof via an IPsec tunnel. The authentication
when connecting to an IPsec terminal device via certificates or a
passphrase (PSK) is supported with this. Up to 10 tunnels can be estab-
lished at the same time.
IPT protocol
The MLR 3G 2.0 supports the communication via IPT (Internet Protocol Te-
lemetry). The MLR 3G 2.0 can connect to an IPT master as IPT slave and
tunnel payload of the serial Ethernet gateway to another IPT slave.
Dynamic DNS Update
The assigned IP address can be deposited at a dynamic DNS service (e.g.
DynDNS) after the set-up of a PPP connection to an Internet service pro-
vider . The MLR 3G 2.0 can be contacted out of the Internet.
