I have two independent networks that, due to security reasons, cannot allow access to each other. Yet, I have a QNAP NAS on the Public network (A), which needs to be accessed from the second "in-house" network (B). I have a computer running Windows Server 2008 which connects to both networks and tried using the 'routing and remote access' feature to allow network (B) to access the NAS on network (A) with no success.

Network (A) has its IP addresses assigned to it through a DHCP Server (Not the local windows server 2008). Example of QNAP NAS: IP: 10.26.71.63 (DHCP Assigned IP) Subnet Mask: 255.255.255.0 Default Gateway: 10.26.71.1

Network (B) has all static IP addresses. Example of a single machine on network (B): IP: 192.168.0.27 (Static IP) Subnet Mask 255.255.255.0 Default Gateway: none

The local Windows Server 2008 has two network cards: Server Network (A) DHCP Assigned IP IP: 10.26.71.109 Subnet Mask: 255.255.255.0 Default Gateway: 10.26.71.1

Server Network (B) Static IP IP: 192.168.0.1 Subnet Mask 255.255.255.0 Default Gateway: none

I tried using RRAS with the lan option, and when i set the gateway on a Network (B) machine to 192.168.0.1 I could then ping the other network card (10.26.71.109) on the Windows Server 2008 Machine, but could not reach any IP beyond that for network (A). I know that bridging the cards would allow me to accomplish this, but I cannot allow the computers on Network (B) to interact with Network (A) other than this one instance.

How can i utilize Windows Server 2008 to make this work? Thanx.

  • By NAS, I assume you mean a shared folder? Or do you want to share an entire drive? You should be able to just Share it an have it visible on both networks. IE. \\10.26.71.63\share and \\192.168.0.1\share should point to the same location. – YetiFiasco Aug 8 '14 at 12:41
  • Wouldn't he need to look at setting up some rules and routes because the networks have been separated for security purposes... – Kinnectus Aug 8 '14 at 12:58
  • No, both networks point to the server and can connect to the server, as far as the server is concerned, it's both 10.26.71.63 AND 192.168.0.1, so unless any rules or permissions are put in place, both IP addresses would lead to available shares. – YetiFiasco Aug 8 '14 at 13:09
  • It is a QNAP NAS Box which is connected to network (A) and has it's IP assigned by a DHCP Server. It is utilized for our database system, backups, etc. and i would like to be able to directly access it from network (B). I will try Mapping it as a drive on the server then sharing it, but if i recall correctly, you can't share a mapped drive. – T.Copeland Aug 11 '14 at 15:13
  • Okay, I was able to successfully connect to the NAS by setting up RRAS-NAT on the windows server 2008. This enabled me to connect to the NAS through the server's IP address and keep the security i needed. Now, i am having problems with the name resolution of the QNAP NAS. Its name on the network is KP-NAS yet i can only connect to it through explorer by using its IP address. What settings have i missed? – T.Copeland Aug 12 '14 at 18:35
