Functions MoRoS GPRS 2.1 PRO
Configuration via the web interface
In order to use the OpenVPN client for a connection, check in the menu
"Dial-In", "Dial-Out", or "LAN (ext)" on the page "OpenVPN client" the
checkbox "Activate OpenVPN client".
In order to define the IP address or the domain name of the remote termi-
nal, which you use to have the MoRoS GPRS 2.1 PRO establish the
OpenVPN connection, enter an IP address or a domain name in the field
"IP address or domain name of remote site".
Optionally, an alternative remote terminal can be defined, which will be
used by the MoRoS GPRS 2.1 PRO to establish the OpenVPN connection,
if the remote terminal configured above is not available. Enter an IP ad-
dress or domain name into the "Alternative remote site" field for this.
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)".
The OpenVPN transmission protocol is selected with the radio buttons
"UDP" or "TCP". We recommend to use UDP to minimize latency.
In order to set a default route, check the checkbox "Set default route (redi-
rect-gateway)". The complete data traffic will be routed through the tunnel
then.
It is not obligatory to provide the local port and the IP address of the
OpenVPN connection. If you want to leave the use of ports and the IP ad-
dress free, uncheck the checkbox "Bind to local address and port".
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
