Now you need to give some random IP address pool series to your DHCP from which it assigns an IP to your computer system ethernet card interface and to Synology NAS box.

Check the HTTP Web server box to get the webserver protocol compatibility.

Select the Ethernet card interface that you used to connect the Synology NAS and click on the Next button.

After running, the DHCP configuration file clicks on the Next button.

Right-click on the dhcpwiz.exe file to configure the DHCP server on your Windows system. Inside the folder, you will find the three files and folder.

Now get back you to the downloaded and extracted DHCP for Windows software folder and open it.

Double click on that ethernet adapter after than on the Details button and you will see under the IP address section you are getting the APIPA ( Automatic Private IP Addressing).

Like in my case it is Ethernet 3 and might be different in yours.

Now identify the Ethernet Adapter for which you have plugged the Ethernet cable from your Synology NAS box.

After extracting, go to Start-> Control Panel- Network & Internet-> Network and Sharing from the right side click on the Change Adapter Settings option.

After downloading the DHCP server portable software which is in ZIP format unzip to extract the files.

When you connect the Synology NAS directly to the PC, both NAS and your Windows PC need unique identification or IP address in order to communicate with each other.

So, we need to create one on our own Windows operating system. But unfortunately neither we have a router nor any external DHCP server. Actually, as soon as you connect the NAS to your computer it starts looking for an IP address from a DHCP server.

Wait until you get a beep that means the NAS system successfully booted up.

Now use an ethernet cable to connect the NAS with your PC.Look at the backside of Synology NAS you will find an Ethernet LAN port.For this tutorial, we are using the Synology DS218j NAS.So here in this tutorial, we will let you how to directly connect your Windows PC with Synology using Ethernet cable but without a router. Recommended: First, try the alternate method given at the bottom and then the first. What will you do at that moment to access the files resides on your NAS? Connecting the Synology via a router and using the Synology Assistant is so easy but what happens when you don’t have a router and external DHCP to provide an IP address to your NAS but still, you want to connect it directly with your personal Windows Laptop or PC.
