Hyper-V synthetic nic can't handle 'resets'

Hi.

Using Hyper-V with Astaro Security Gateway, works well,
but everytime my cable modem resets, for firmware upgrade, or whatever,
Astaro loses connection with the network interface that Hyper-V provides.

The moment my cable modem resets, the NIC in Windows that has the Virtual Switch Protocol enabled, says 'Cable Disconnected', followed by 'Cable Connected'. But from that moment on, Astaro remains disconnected.

Strangely enough when I manually disable that adapter and then Enable it again, Astaro picks this up, and the connection is running again.

Is this a bug that can be fixed? Would be great!

Cheers,
