I have a Windows 2012 R2 server which has 4 NICs. Two of these NICs are connected to seperate private networks(not connected to internet). NIC3 is connected to 192.168.137.1 (Subnet mask: 255.255.255.0) and NIC4 to 192.168.1.1(same subnet mask). All the PCs in NIC3 and NIC4 are configured with static IPs corresponding to the network they are in.

I want to access a printer on NIC4 (IP: 192.168.1.200) from my PC in NIC3 having IP: 192.168.137.171. I am unable to ping the printer.

I have tried everything from bridging the connections of NIC3 and NIC4 to enabling sharing of Internet connection of NIC4 with NIC3. Nothing works. What can be done here?

  • Assuming your computers are connected to a local switch, you should add a static route on your switch, otherwise you won't be able to access one network from the other one – Bogdan Stoica Jul 10 '18 at 05:15
  • How can I do that? I dont think we have managed switches – Abhishek Agarwal Jul 10 '18 at 05:26
  • I don't know your actual setup from there so it's pretty hard to say. They should be connected somehow right. Your network has to has a gateway defined right for each of your subnets... – Bogdan Stoica Jul 10 '18 at 05:28
  • The gateways are taken by default as I have left them blank on the configuration of NIC3 and NIC4 cards on server – Abhishek Agarwal Jul 10 '18 at 05:31
  • Who's responsible for providing the gateways? There should be a computer or a server or a switch or whatever that is doing that.... – Bogdan Stoica Jul 10 '18 at 05:32
  • I just checked on my PC in NIC3 has the default gateway same as the IP address of NIC3 configured in server(192.168.137.1). I think the default gateway is the same as IP of NIC based on the network you are in – Abhishek Agarwal Jul 10 '18 at 05:34

    Enable routing on the server then set the default gateway of all machines to be the IP address of each corresponding NIC on the server. https://www.dell.com/support/article/us/en/19/how10169/configuring-windows-server-2012-r2-as-a-router?lang=en you just don’t want to use NAT between the two networks. You can also use the server as a DHCP server so you can get rid of those god forsaken static IP addresses. – Appleoddity Jul 10 '18 at 06:30
