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 No-IP.com or DYNDNS.org which require users to go to those sites and create user accounts which are then added to the router configuration.
