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.
