68D-Link DCS-5230 User Manual
Section 4 - Security
Note: Because a dynamic WAN IP can change from time to time depending on your ISP, you may want to obtain a
Static IP address from your ISP. A Static IP address is a xed IP address that will not change over time and will be
more convenient for you to use to access your camera from a remote location. The Static IP Address will also allow
you to access your camera attached to your router over the Internet.
4. Open Virtual Server Ports to Enable Remote Image Viewing
The rewall security features built into the DIR-655 router prevent users from accessing the video from the DCS-5230
over the Internet. The router connects to the Internet over a series of numbered ports. The ports normally used by the
DCS-5230 are blocked from access over the Internet. Therefore, these ports need to be made accessible over the
Internet. This is accomplished using the Virtual Server function on the DIR-655 router. The Virtual Server ports used
by the camera must be opened through the router for remote access to your camera. Virtual Server is accessed by
clicking on the Advanced tab of the router screen.
