Using The Dvc-1100 With Routers, Gateways Or Modems - D-Link DVC-1100 Manual

Using the DVC-1100 with Routers, Gateways
or Broadband Modems
Opening Ports on Your Routers and Gateways
The firewall security features built into most routers and gateways may prevent
users from accessing the video and audio of their DVC-1100.
A router connects to the Internet through a series of numbered ports. The ports
used by the DVC-1100 are often blocked from access over the Internet by the
firewall features of the router.
You may be able to connect to another VideoPhone, but not receive any video
or audio. This is a typical scenario of a firewall blocking the ports needed by the
DVC-1100 to send audio and video.
If this is the case, you need to open the ports on your router to the Internet to
allow access to the DVC-1100.
The port numbers used by the DVC-1100 are:
1720
15328
15329
15330
15331
15332
15333
The router or gateway that you are using may be different from the D-Link
DI-614+ wireless router example shown on the following pages. However, the
general procedure for opening ports will be similar. (If you do not have a D-Link
router, look for Virtual Server, Firewall Rules, Port Forwarding, Advanced or
Firewall in your router's configuration utility.)
In the example that follows, we begin by opening the DI-614+ Web configuration
utility and going to Advanced > Virtual Server.
Follow the steps on the next 2 pages to open the ports on your router for
successful operation of the DVC-1100.
