Functions
MLR 3G 2.0
www.insys-tec.de/en/en/driver/
This program is used as remote terminal, if you want to establish an OpenVPN connec-
tion to a Windows PC.
Configuration with the web interface
In order to use
the OpenVPN server for a connection
, check in the menu "Dial-
In" or "Dial-Out" on the page "OpenVPN server" the checkbox "Activate
OpenVPN server".
In order to
define the local port at the MLR 3G 2.0 as well as the port at the
remote terminal
, enter a value for the required port into the entry fields "Tun-
nelling over port (local / remote)" (default setting 1194).
The
VPN transmission protocol
is selected with the radio buttons "UDP" or
"TCP". We recommend using UPD to minimise latency.
In order to
inform the clients about the route to the network behind the
server
, check the checkbox "Inform clients about server network". If this set-
ting is disabled, a communication can only be initiated from the network of
the server.
In order to
enable remote VPN terminals to change its IP during a connection
("
Floating
"), check the checkbox "Remote terminal is allowed to change its IP
address (float)". This setting is activated by default.
In order to
enable or disable LZO compression
, check or uncheck the checkbox
"Activate LZO compression". If already strongly compressed data (e.g. jpg) is
transmitted, the compression will have hardly any effect; however, if com-
pressible data (e.g. text) is transmitted, the compression may significantly re-
duce the transmitted volume of data. Switch the compression off, if the re-
mote terminal does not support LZO compression.
In order to
mask the packets with the virtual tunnel IP address
, check the
checkbox "Masquerade packets before tunnelling". The recipient of the pack-
ets sees the IP address of the tunnel end as sender then, not the address of the
original sender.
In order to
use a different encryption method
than the preset method "Blow-
fish 128 Bit" for the VPN connection, select one of the following encryption
types in the drop-down menu "Cipher algorithm":
(Blowfish 128 Bit), DES 64 Bit, DES EDE 128 Bit, DES EDE3 192 Bit,
DESX 192 Bit, CAST5 128 Bit, IDEA 128 Bit, RC2 128 Bit, RC2 40 Bit, RC2 64 Bit,
AES 128 Bit, AES 192 Bit, AES 256 Bit
In order to configure the
detail level of the messages in the connection log
,
enter the detail level into the field "Log level", where "0" disables the log re-
cord completely and "9" records the most detailed information.
In order to define a certain
fragmenting size for the VPN tunnel packets
in
bytes, use the entry field "Fragment packets". Enter the required maximum
packet size in bytes here. If you don't enter a value, the VPN packets will have
a maximum size of 1.500 bytes. The actually transmitted amount of user data
is lower, because VPN creates a "protocol overhead", which means that the
protocol information that is transmitted as well is a part of the packet size.
