Yup, tama lang na Bridged yung modem and the router hosts the connection. This is the ideal setup. If you use the Prolink as a router, then put the LAN IP address of the CCTV equipment on the "local IP", and then port range to 8080-8080 for local and public ports. I think you can skip putting values in the remote IP address. You can also try putting the CCTV LAN IP on the DMZ of the router to test if you can access it remotely.
