The D-Link DIR-825 can be configured as a virtual server so that remote users accessing Web or FTP services via the public IP address can be automatically redirected to local servers in the LAN (Local Area Network).

The DIR-825 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked with the DIR-825 are invisible to the outside world. If you wish, you can make some of the LAN computers accessible from the Internet by enabling Virtual Server. Depending on the requested service, the DIR-825 redirects the external service request to the appropriate server within the LAN network.

The D-Link DIR-825 is also capable of port-redirection meaning incoming traffic to a particular port may be redirected to a different port on the server computer.

Each virtual service that is created will be listed at the bottom of the screen in the Virtual Servers List. There are
pre-defined virtual services already in the table. You may use them by enabling them and assigning the server IP to use that particular virtual service.

Name:Enter a name for the rule or select an application from the drop-down menu. Select an application and click << to populate the fields.

IP Address:Enter the IP address of the computer on your local network that you want to allow the incoming service to. If your computer is receiving an IP address automatically from the router (DHCP), you computer will be listed in the “Computer Name” drop-down menu. Select your computer and click <<.

Private Port/ Public Port:Enter the port that you want to open next to Private Port and Public Port. The private and public ports are usually the same. The public port is the port seen from the Internet side, and the private port is the port being used by the application on the computer within your local network.

Protocol Type:Select TCP, UDP, or Both from the drop-down menu.

Schedule:The schedule of time when the Virtual Server Rule will be enabled. The schedule may be set to Always, which will allow the particular service to always be enabled. You can create your own times in the Tools > Schedules section.

Inbound Filter:Select Allow All (most common) or a created Inbound filter. You may create your own inbound filters in the Advanced > Inbound Filter page.

Description

D-Link DIR-651 Wireless N 300 Gigabit Router Connect you desktop computer to a wireless network and access a high-speed Internet connection, transfer files and stream media from greater distances across your home than previous-generation Wireless G* technology.

BEST-IN-CLASS FEATURES

The D-Link Wireless N 300 Gigabit Router (DIR-651) comes equipped with 4 Gigabit ports to provide speeds up to 10x faster* than standard 10/100 ports. It also uses 802.11n technology with multiple intelligent antennas to maximize the speed and range of your wireless signal to significantly outperform 802.11g devices1. With the addition of Intelligent Quality of Service (QoS), data streams are separated which helps organize and prioritize your network traffic so your video streaming, gaming, and VoIP calls run smoother over both your wired and wireless network.

1.Maximum wireless signal rate derived from IEEE Standard 802.11 specifications. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, buildings materials and construction, and network overhead, lower actual data throughput rate. Environmental factors will adversely affect wireless signal range. Wireless range and speed rates are D-Link RELATIVE performance measurements based on the wireless range and speed rates of a standard Wireless G product from D-Link. Maximum throughput based on D-Link Wireless N devices.

2.1-Year Limited Warranty available only in the USA and Canada.

3.Computer must adhere to Microsoft’s recommended System Requirements.

4.The software included with this product is not Mac-compatible.

Reviews

It looks like D-Link wants to offer a competitor to Cisco’s new Linksys E1500 budget router.
According to D-Link, this new single-band router features multiple intelligent antennas, and supports Intelligent Quality of Service, which aids in optimizing Internet traffic for services such as VoIP or gaming.

Most significant, however, is the fact that D-Link’s new router supports Gigabit Ethernet, which the E1500 doesn’t. This means wired clients can enjoy network speeds of up to 1000Mbps, and those with a home server can enjoy media streaming to multiple devices without worrying about clogging their networks.

Like most wireless routers, the D-Link DIR-651 comes with four LAN ports and one WAN port. For security, the router also supports all variations of WPA and WPA2 standards. In addition, it supports Wi-Fi Protected Setup (WPS), so you can add WPS-enabled clients to the network with the push of a button.

The DIR-651 Wireless N 300 Gigabit Router is slated to be available next month for an estimated price of $90, about the same as that of the Linksys E1500.
