Port Forwarding

Port Forwarding Info

  • IF an ISP does not allow user configuration of a device then the device must be put into “Bridge” mode and a second router must be added so that configuration can take place.
  • In the case of DSL and Cable there must be an open port for either an NVR/DVR or Camera to connect.
  • YOU MUST have a PC with you to configure router. This CANNOT be done via the DVR/NVR.
  • Some Devices only require one port such as the http port. Other devices require http and media port. Others can require http, media/rtsp and server ports.
  • Where you go next can vary greatly. Some routers put port forwarding under “Applications and Gaming”. Others under Advanced Options/Pin Holes or Advanced Options/Port Forwarding. Refer to Router user Manual.
  • The CCTV device to which you are forwarding needs to have a static address. You cannot have DHCP enabled on device.
  • DHCP (Dynamic Host Communications Protocol) means the device is “set to obtain IP address automatically (computers are set this way by default).
  • Which address is assign to which device is dependent which device boots faster. It is very likely that device will a different address causing ports to be forwarded to wrong device.
  • If you can connect to the DVR/NVR/IP Camera across the network but do not get video then one of the ports may not be forwarded correctly.
  • It may be necessary to reboot the device in order for network changes (like changing the RTSP port) to take effect.
  • Many routers support services that will allow a user to create a name that will be associated with a changing Public IP address. Most (D-Link has their own server) use third part servers such as or which require users to go to those sites and create user accounts which are then added to the router configuration.
