Hello, I am not trained in networking but I have to install our new network equipment.
We currently have Comcast Business Class cable modem internet service. We have purchased a Sonicwall NSA 220W device and 2 Cicso SG102-24-NA 24-port switches. To add to this, we have a Synology DSW213+ NAS device used for centralized file storage. I have planned to connect the Sonicwall NSA 220W WAN port to the Comcast modem LAN port with a straight ethernet patch cord. Then connect one of the Sonicwall LAN ports to the first port of Cisco 24-port switch with a straight Ethernet patch cord. Then connect the first Cisco switch from one of it's ports to the first port of the second Cisco switch with another straight Ethernet patch cord. Then lastly I'm not sure where I should connect the Synology NAS? To one of the switches or directly to the Sonicwall? I am asking for the correct/best way to connect these devices and the correct type of Ethernet cable to use? The Sonicwall or Comcast modem will be providing DHCP with a Sonicwall IP of 192.168.1.1 as the Gateway and providing a range of 192.168.1.2 thru 192.168.1.254. Thanks for your help!
