I set up a vpn sever on ubuntu on a virtual machine running on a windows server 2008 host and all my hdd are (connected) and installed just in the host system. I can connect to the network by vpn and ping each device in the network.
My problem is that i'd like to mount all my drives, with eg my laptop which has ubuntu running having the mount command in my fstab, automatically. How can I do this? Is it necessary to be already connected to the network to mount the devices by fstab? I mean it's hardly feasible, just to get an idea of it... or is ist possible to mount it afterwards with some special commands ? Or do I have to make any changes to VirtualBox or something? Maybe theres someone out there who had the same problem, help me out!

Thanks for your attention
