CHAPTER 2. OVERVIEW
General Information
DSL-G2452GR is a multifunction LTE/3G/VDSL/ADSL/Ethernet router with Wi-Fi and built-in switch. The router allows accessing the Internet via LTE or 3G network (with a USB modem1 connected). In addition, the device allows accessing the Internet via VDSL/ADSL technology and via Ethernet technology.
The router is equipped with a DSL port to connect to a high-speed VDSL line and 4 Ethernet ports to connect workstations. Due to this feature, DSL-G2452GR represents a moderate-priced solution for creating wired networks without an additional switch. Any Ethernet port of the device can be used to connect to a private Ethernet line. In addition, Gigabit Ethernet WAN port enables you to connect the device to a high-speed Ethernet line. Also the router has a USB port designed to connect a USB modem, printer, or USB storage.
Using the DSL-G2452GR device, you are able to quickly create a high-speed wireless network at home or in your office, which lets computers and mobile devices access the Internet virtually anywhere (within the operational range of your wireless network). Simultaneous activity of 2.4GHz band and 5GHz band allows performing a wide range of tasks. The router can operate as a base station for connecting wireless devices of the standards 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac (at the wireless connection rate up to 1167Mbps2).
The router supports multiple functions for the wireless interface: several security standards (WEP, WPA/WPA2), MAC address filtering, WPS, WMM.
In addition, the device is equipped with a button for switching the Wi-Fi network off/on. If needed, for example, when you leave home, you can easily switch the router's WLAN by pressing the button, and devices connected to the LAN ports of the router will stay online.
Multi-user MIMO technology allows to distribute the router's resources to let multiple wireless clients use the Wi-Fi network efficiently, keeping high rates for HD media streaming, lag-free gaming, and fast transfer of large files.
Support of guest Wi-Fi network allows you to create a separate wireless network with individual security settings and maximum rate limitation. Devices connected to the guest network will be able to access the Internet, but will be isolated from the devices and resources of the router's LAN.
The wireless router DSL-G2452GR includes a built-in firewall. The advanced security functions minimize threats of hacker attacks, prevent unwanted intrusions to your network, and block access to unwanted websites for users of your LAN.
The device is equipped with two FXS ports which allow connection of analog phones for calls via Internet.
In addition, the router supports IPsec and allows to create secure VPN tunnels.

DMZ
A DMZ is a host or network segment located "between" internal (local) and external (global) networks. In the router, the DMZ implements the capability to transfer a request coming to a port of the router from the external network to a specified host of the internal network.
On the Firewall / DMZ page, you can specify the IP address of the DMZ host.

To enable the DMZ, move the Enable switch to the right. Enter the IP address of a host from your network in the IP address field. To choose a device connected to the router's LAN at the moment, select the relevant value from the drop-down list (the field will be filled in automatically). Move the Enable NAT Loopback switch to the right in order to let the users of the router's LAN access the DMZ host using the external IP address of the router or its DDNS name (if a DDNS service is configured). Users from the external network access the router using the same address (or DDNS name). Click the APPLY button. Note that when the DMZ is enabled, all traffic coming to a port of the WAN interface of the router is directed to the same port of the specified IP address. Also note that virtual servers have higher priority than the DMZ host. In other words, if there has been created a virtual server that directs traffic from external port 80 to a port of the device from the router's local network, then entering http://router_WAN_IP in the address bar, users of the external network are directed to the specified port and IP address configured for the virtual server, but not to port 80 of the device with the IP address specified on the Firewall / DMZ page. To disable the DMZ, move the Enable switch to the left and click the APPLY button.

Wireless Installation Considerations
The DSL-G2452GR device lets you access your network using a wireless connection from virtually anywhere within the operating range of your wireless network. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF noise in your home or office. To maximize your wireless range, follow the guidelines below.
1. Keep the number of walls and ceilings between the DSL-G2452GR device and other network devices to a minimum each wall or ceiling can reduce your wireless network range by 3-90 feet (1-30 meters).
2. Be aware of the direct line between network devices. Place your devices so that the signal travels straight through a wall or ceiling (instead of at an angle) for better reception.
3. Building materials make a difference. A solid metal door or aluminum studs may have a negative effect on your wireless range. Try to position your router, access points, and computers so that the signal passes through drywalls or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your router away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.
5. If you are using 2.4 GHz cordless phones or X-10 equipment (wireless devices such as ceiling fans, lights, and home security systems), your wireless connection may degrade dramatically or drop completely. Make sure your 2.4 GHz phone base is as far away from your wireless devices as possible. Note, that the base transmits a signal even if the phone in not in use.
