    Best NAS with dual nic's for 2 networks

    I have a client with 2 separate networks, 1 network is isolated from the internet and the other isn't. I want to be able to share their data between both networks since each user has 2 desktop PC's.

    What NAS with dual nic's are capable of doing this?

    I have researched almost all of the NAS's out there, but I am not 100% sure that these NAS's can use both nic's at the same time. It seems majority are fail-over or load balancing type setups.

    Thanks in advanced.

    Netgear Business dual NIC NAS products will support multiple networks and/or VLAN. Alternatively the dual ports can be used for teaming/failover. The Netgear consumer products support dual networks only.

    I'm fairly sure QNAP and Synology are fairly similar to Netgear Business products.

    Thanks for that info, looks like the QNAP's is the way to go for my scenario.

    One more question,

    do you know if its possible on these 4-bay systems to use only 2 bays for a RAID 1 setup for file sharing and use the other 2 bays for a stand alone data drive, i.e; possible backup drive?

    Thanks

    Generally, no.

    While it is certainly possible to setup a raid 1 volume with 2 disks, and another raid 1 with the other 2 disks (or 2 individual raid 0 volumes), raid is not designed to be have the disks be removed/readded in such a manner as you desire.

    Also, this may prevent any future expansion capabilities of the main array.

    Your best bet is to find a device with usb and/or esata and use the builtin backup scheduler to backup to the usb/esata drives.

    Backdoor

    will this leave a backdoor open to the closed network (that currently does not have internet)?

    or is it impossible to get from wan to nas and via nas to closed network and to a pc or server connected to closed network?

    Nothing is impossible, however the two NICs will be on separate networks or VLAN which is designed to isolate the two. However all bets are off if the NAS vendor has code issues that can be exploited.

    Scenario

    Great, thanks for reply.

    The following scheme I am worried about:

    I have the NAS connected to 2 separate networks

    NIC 1 is connected to 10.0.0.3
    and
    NIC 2 is connected to 192.168.1.10

    These are 2 separate networks with their own wiring and their own internet-connection.
    One has internet from e.g. AT&T and the other one from Orange.
    So two completely separate networks.

    I have windows 7 machines on both networks.

    The network with "10.0.0.3" is a closed network with strong firewall, and with limitations of use on proxy-server etc etc.
    The network with "192.168.1.10" is ordinary network with hardware firewall and firewalls on windows machines.

    I am a bit worried if someone can use the NAS and access computers on network 1 via the network 2 NAS-NIC. But this should almost be impossible?

    Its a ReadyNAS NVX from Netgear.

    Best regards
    Morten
