MoRoS GPRS 2.1 PRO Functions
ing transmission, how big the tunnel packets are to be, and in which time intervals
the OpenVPN server sends VPN pings. In addition, you will have the option to dis-
play the OpenVPN status, to display the current configuration file, to create a con-
figuration for an OpenVPN remote terminal, and to display a log of the last connec-
tion. You can use the generated configuration file to create an OpenVPN configura-
tion file for exampple, which can be used as basis for the operation of an OpenVPN
instance on a client PC. The OpenVPN packet for Windows clients can be
downloaded from the INSYS MICROELECTRONICS web site:
www.insys-tec.de/en/en/driver/
This program is used as remote terminal, if you want to establish an OpenVPN con-
nection to a Windows PC.
Configuration via the web interface
In order to use the OpenVPN server for a connection, check in the menu
"Dial-In", "Dial-Out", or "LAN (ext)" on the page "OpenVPN server" the
checkbox "Activate OpenVPN server".
In order to define the local port at the MoRoS GPRS 2.1 PRO as well as
the port at the remote terminal, enter a value for the required port into the
entry fields "Tunnelling over port (local / remote)" (default setting 1194).
The OpenVPN 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
setting is disabled, a communication can only be initiated from the net-
work of the server.
In order to enable remote OpenVPN 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 compressible data (e.g. text) is transmitted, the compression
may significantly reduce the transmitted volume of data. Switch the com-
pression off, if the remote 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
packets sees the IP address of the tunnel end as sender then, not the ad-
dress of the original sender.
In order to use a different encryption method than the preset method
"Blowfish 128 Bit" for the OpenVPN connection, select one of the follow-
ing encryption types in the drop-down list "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
