Port Forwarding

Most home routers or gateways use a NAT firewall to protect your home network from the Internet. NAT or Network Address Translation works by hiding your computer’s IP address from internet devices and replacing it with the gateway IP address. It will then forward internet traffic to the proper computer. To further protect your home network, the NAT firewall disallows unrequested traffic from the internet. Some applications, such as Torrents and Remote Access, require unrequested inbound connections. To use these features with your StorCenter device, you will need to configure your router to allow inbound connections for these applications. This is known as Port Forwarding.

The port forwarding process is dependent on the brand and model number of the router being used. Port forwarding of a router is required with your system to allow user access to your DVR. Although a firewall will block all requests from the outside world by default, there may be times when you actually want to allow external users into your network. For example, you want to access your DVR while away from your home or office. Because the default configuration of most firewalls blocks all external requests, you’ll need to open things up using a feature known as port forwarding.

Remember that in almost all cases, your internal network will be configured to use private IP addresses. Because of this, you’ll need to configure your firewall to take requests destined for your public or “real” IP address and forward them to the your DVR. When a user on the Internet needs to contact a DVR, the request is forwarded to the IP address of the DVR, and the port on which the DVR Web server is running. By default, all of our DVRs are configured to listen for requests on TCP port 88. So, what you would need to do in this case is tell the firewall that every time the public IP address receives a request destined for TCP port 88, it should forward the request to TCP port 88 on the Web server running on 192.168.1.50. The manner in which this is configured depends upon the firewall you are using.
