Functions
MoRoS ADSL 2.1 PRO
In order to adjust the VPN ping interval, use the entry field "Ping
interval". Enter the interval in the amount of seconds, in which the
OpenVPN client of the MoRoS ADSL 2.1 PRO 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.
In order to adjust the ping restart interval, use the entry field "Ping restart
interval". 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 has arrived during the complete time. The value "0" prevents the
tunnel to be terminated, even if no ping is received any more.
In order to send a ping via ICMP protocol to a domain or an IP address
additionally, enter this into the entry field "Additional ICMP Ping to". It is
recommended to enter a domain name or IP address, which can only be
connected via the tunnel, here. If the ping is not successful, a possibly
existing tunnel will be terminated, and a new tunnel will be established.
The ping interval is 15 minutes.
In order to configure the authentication with certificates, select the radio
button "Authentication based on certificate". It is indicated under the
option here, whether the individual certificates and keys are present
(green checkmark) or not (red cross). Present certificates can also be
downloaded (blue arrow) or deleted again (red cross on white box). The
private key can only be deleted. Alternatively, or in addition to the usage
of a client certificate and a private key, an user name/password
combination can be used for the authentication with the OpenVPN server
(however, the CA certificate is required in any case, which must be
possessed by every participant of this VPN). Enter a user name into the
field "User name" as well as the associated password into the field
"Password" for this. In order to check the certificate type of the remote
terminal, check the checkbox "Check remote certificate type".
