Non stable VPN traffic

Hi all,
I am using an Endian for eWON 100 to create just a VPN. We have 23 users and lastly we have some problems with the communication to the eWONs because it seems that the connection is not too stable. See enclosed the traffic graphs of the endian (incoming traffic) as after 10sec or so reciving data (endian traffic 2) the connection goes down several times (endian traffic) and the same situation again.

Another router (Vigor Draytek) takes over the network security so the Endian is complete open and free to allow all the traffic through the VPN. If I ping the eWONs (200 packages) I get around 12% of losses what is an issue to reach some divices behind the eWON.

Thanks in advance,
Alberto
