Hello Guys/Gals
I have a little problem to set up one of my Windows-Machines as a little data-center (DC) running Win10
My motherboard has two Network-Ports and the PC is located in a big university network and is connected by wire to it.
In the same room are three analysis machiches which produce some nice amounts of data(Data-Producers(DP)) running Win 8.1
My plan was now the following:
1. connect the analysis computer DP using a Network Splitter and a shared Folder on the DC so that the DPs can send data via cable directly to the DC. (cant make it work )
2. connect the DC to the University-Network for Internet and Off-Site access ( accomplished) (fixed IP, Subnetmask, Gateway necessary)
3. Use the Internet-Access from the DC to forward internet to the DPs (for convenience)
The problem now is, that the DPs cant find the DCs shared folders and (of course dont get an internet connection)
Anybody an idea how i can solve the problem ?
Yours sincerely

Hi,
>>Plugging the two Ethernet interfaces to the different networks will work as long as the two LAN are using different IP ranges. There is a significant risk that both LANs are using the same range of RFC 1918 addresses. (RFC 4193 introduce a method to avoid such conflicts, but that is for IPv6 only.)
If the two LANs are using the same IP addresses, you first need to reconfigure one of the routers, such that they no longer use conflicting addresses.
Once you have ensured that the two LANs use non-conflicting addresses, you can plug in the server. You should configure the server with static IP addresses on each Ethernet interface. The IP address obviously need to match the LAN it is connected to, and it need to be assigned an IP address which is not in the range used by DHCP.
Each LAN has a default gateway. On the server you only configure the default gateway on one of the interfaces, that will be the one it will use for internet connectivity. If you want to, you can configure individual routes, that will let the server reach some remote destinations through the other router.
One caveat to notice in this setup is that the clients on the two LANs will need to use different IP addresses to reach the server. You can get around that if you can configure a static route on one of the routers.
For example if the routers are 192.168.1.1 and 192.168.2.1, and the server has IP addresses 192.168.1.2 and 192.168.2.2, you can configure a static route on 192.168.1.1. That static route will say that in order to reach 192.168.2.2 the gateway to use is 192.168.1.2.
If configured like that, then clients on both LANs can reach the server using 192.168.2.2.

Thank you very much for the fast reply.
So if i understood correctly.
1. The Data-Servers(DC) first NIC (which goes into the university network) is configured how it has to be to gain access there.
2. The second NIC is configured with a "totally" different IP-Range, but uses the IP from the first NIC as a gateway?
3. The second NIC goes into a switch ( i dont have a second router in between) and the Analysis-PCs are also connected to the same switch.
4.Setting the IP-Addresses on the Analysis-PCs in the same range then the second NIC of the DC and the IP-address of the first NIC as a gateway ?
5. When i now want to access the the shared drive on the DC i have to use the IP from the 2nd NIC, since this is connected to the switch.
Did that made sense or did i miss something again?
Thank you so much again for the detailed explaination.
Sincerely
Sack
