KEYLOK HID Mode Dongle work only on lan e not on opevpn connection

Hi i'm using virtualhere server on windows pc (no firewall) with 4 different dongle:

1.KEYLOK HID, HASP HL 3.25, KEYLOK II and another one. Every thing works well on lan and on VPN exept for Keyloc HID mode dongle that dont work.

Latency is 70ms on vpn, but the application that use keylock HID won't start on vpn. The same application use keylock II dongle work perfect on vpn, but when i use the other one no.

I've optimized everything on vpn connetion, use split configuration,udp buffer etc. 

There is something that i can do on virtualhere server/client configuration to use this dongle.

Thanks
