Network Card problem after rebooting my router.

Hello all,

I stumbled upon a problem on my server.

I have a mac running on OS X 10.9 with an ubuntu VM.

It's configured in bridge mode with a specific IP different from the host.

When I loss connection to the router box and reactivate it (hard reboot), the VM become unaccessible from other computers, only the host can access it (apache, through a web browser).

I have to disconnect/reconnect the virtual LAN Card in order to make it working back.

Any clue about that ?

Is there any solution for making the connection permanent, as a server I can't/don't want to fiddle with this hassle, the Virtual bridged LAN Card should reconnect after any LAN/internet access loss.

Cheers.
