ok i have switched the cables on unraid, so my pc is now connected to the 1gb intel nic on unraid while the main cable is connected to the 2.5gb, no more packet loss when transferring
i consider this a solution but not the ideal condition

thank you very much for your reply. i was wondering why it stopped working, without changing any parameter in the vpn
and as long as the network connection is normal working in unraid it should work
 
i had also trouble with the modem/router fritzbox 7530ax, i have replaced it with my old device 7560 and reapplied the config the same way..
 
now it works again, so it seemed to be an issue with the static routing but as settings are identically i expect it to be an FritzOS issue
