The
VPN transmission protocol
is selected with the radio buttons "UDP" or
"TCP". We recommend using UPD to minimise latency.
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
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.
In order to
adjust the interval up to the key renegotiation
, use the entry field
"Interval for renegotiation of data channel key". This interval configures the
time in seconds, which must expire before new keys are created.
In order to adjust the VPN ping
interval
, use the entry field "Ping interval". En-
ter the interval in the amount of seconds, in which the VPN Server of the Mo-
RoS LAN PRO 2.0 sends ping packets to the remote VPN terminal. The frequent
ping is used to keep the connection open via several routers and gateways,
which may participate in the connection and would close the channel in case
there was no communication. We recommend entering a value of a few min-
utes, depending on the used network and the used infrastructure.
In order to adjust the ping restart
interval
, use the entry field "Ping restart in-
terval". The ping restart interval configures the time in seconds after which
the tunnel is to be established again, if no ping from the remote terminal ar-
rived during the complete time. The value "0" prevents the tunnel to be ter-
minated, even if no ping is received anymore.
