Hi everyone,

I have TWO linux machines in my office. One is on LAN (only locally-accessible) and the other on WAN (WWW-accessible). On the WAN, I have an apache server running but I also mounted a hard drive from the LAN machine using NFS so that I can easily access and transfer data files between the two machines.

My question is:

Is the hard drive from the LAN machine mounted on the WAN computer accessible from outside LAN? In other words, if an hacker breaks into my server on the WAN machine, will (s)he be able to access data on my NFS-mounted hard drive from the LAN machine? I would assume that since IP assigned to my LAN machine is only accessible locally, access from outside LAN to this hard drive will not be available. What do you think?

Thank you for your suggestions.
