I have a modem/router which has 4 LAN ports. Port 1 goes to my desktop computer right next to it and port 2 goes to my Ethernet smart switch TL-SG1024DE. I then have all of my Ethernet coming out of the switch, I have just installed a CCTV which has a stand alone NVR and supports all my Cameras via POE. Which is the best way to structure this from an IP address, have an understanding of it, just need guidance. Thanks
