Chapter 1. Introduction

D-Link Unified Services Routers offer a secure, high performance networking solution to address the growing needs of small and medium businesses. Integrated high -speed IEEE 802.11n and 3G wireless technologies offer compara ble performance to traditional wired networks, but with fewer limitations. Optimal network security is provided via features such as virtual private network (VPN) tunnels, IP Security (IPsec), Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Pro tocol (L2TP), and Secure Sockets Layer (SSL). Empower your road warriors with clientless remote access anywhere and anytime using SSL VPN tunnels.

With the D-Link Unified Services Router you are able to experience a diverse set of benefits:

Comprehensive Management Capabilities

The DSR-500, DSR-500N, DSR-1000 and DSR-1000N include dual-WAN Gigabit Ethernet which provides policy-based service management ensuring maximum productivity for your business operations. The failover feature maintains data traffic without disconnecting when a landline connection is lost. The Outbound Load Balancing feature adjusts outgoing traffic across two WAN interfaces and optimizes the system performance resulting in high availability. The second WAN port can be configured as a DMZ port allowing you to isolate servers from your LAN.

DSR-150/150N/250 /250N have a single WAN interface, and thus i t does not support Auto Failover and Load Balancing scenarios.

Superior Wireless Performance

Designed to deliver superior wireless performance, the DSR-500N and DSR1000N include 802.11 a/b/g/n, allowing for operation on either the 2.4 GHz or 5 GHz radio bands. Multiple In Multiple Out (MIMO) technology allows the DSR-500N and DSR-1000N to provide high data rates with minimal “dead spots” throughout the wireless coverage area.

DSR-150N, 250N and DSR-500N supports the 2.4GHz radio band only.

Flexible Deployment Options

The DSR-1000 / 1000N supports Third Generation (3G) Networks via an extendable USB 3G dongle. This 3G network capability offer s an additional secure data connection for networks that provide critical services.

LAN Setup

It is assumed that the user has a machine for management connected to the LAN to the router. The LAN connection may be through the wired Ethernet ports available on the router, or once the initial setup is complete, the DSR may also be managed through its wireless interface as it is bridged with the LAN. Access the router’s graphical user interface (GUI) for management by using any web browser, such as Microsoft Internet Explorer or Mozilla Firefox:

Go to http://192.168.10.1 (default IP address) to display the router’s management login screen.

Default login credentials for the ma nagement GUI:

Username: admin

Password: admin

 If the router’s LAN IP address was changed, use that IP address in the navigation bar of the browser to access the router ’s management UI.

2.1 LAN Configuration

Setup > Network Settings > LAN Configuration

By default, the router functions as a Dynamic Host Configuration Protocol (DHCP) server to the hosts on the WLAN or LAN network. With DHCP, PCs and other LAN devices can be assigned IP addresses as well as addresses for DNS servers, Windows Internet Name Service (WINS) servers, and the default gateway. With the DHCP server enabled the router’s IP address serves as the gateway address for LAN and WLAN clients. The PCs in the LAN are assigned IP addresses from a pool of addresses specified in this procedure. Each poo l address is tested before it is assigned to avoid duplicate addresses on the LAN.

For most applications the default DHCP and TCP/IP settings are satisfactory. If you want another PC on your network to be the DHCP server or if you are manually configuring the network settings of all of your PCs, set the DHCP mode to ‘none’. DHCP relay can be used to forward DHCP lease information from another LAN device that is the network’s DHCP server; this is particularly useful for wireless clients.

Instead of using a DNS server, you can use a Windows Internet Naming Service (WINS) server. A WINS server is the equivalent of a DNS server but uses the NetBIOS protocol to resolve hostnames. The router includes the WINS server IP address in the DHCP configuration when ackno wledging a DHCP request from a DHCP client.

You can also enable DNS proxy for the LAN. When this is enabled the router then as a proxy for all DNS requests and communicates with the ISP’s DNS servers. When disabled all DHCP clients receive the DNS IP addre sses of the ISP.

Unified Services Router	User Manual

To configure LAN Connectivity, please follow the steps below:

1.In the LAN Setup page, enter the following information for your router:

IP address (factory default: 192.168.10.1).

 If you change the IP address and click Save Settings, the GUI will not respond. Open a new connection to the new IP address and log in again. Be sure the LAN host (the machine used to manage the router) has obtained IP address from newly assigned pool (or has a static IP address in the router’s LAN subnet) before accessing the router via changed IP address.

Subnet mask (factory default: 255.255.255.0).

2.In the DHCP section, select the DHCP mode:

2.1.1 LAN DHCP Reserved IPs

Setup > Network Settings > LAN DHCP Reserved IPs

This router DHCP server can assign TCP/IP configurations to computers in the LAN explicitly by adding client's network interface hardware address and the IP address to be assigned to that client in DHCP server's database. Whenever DHCP server receives a request from client, hardware address of that client is compared with the hardware address list present in the database, if an IP address is already assigned to that computer or device in the database , the customized IP address is configured otherwise an IP address is assigned to the client automatically from the DHCP pool.

Computer Name: The user defined name for the LAN host.

IP Addresses: The LAN IP address of a host that is reserved by the DHCP server.

MAC Addresses: The MAC address that will be assigned the reserved IP address when it is on the LAN.

Associate with IP/MAC Binding: When the user enables this option the Computer Name, IP and MAC addresses are associated with the IP/MAC binding.

The actions that can be taken on list of reserved IP addresses are:

Select: Selects all the reserved IP addresses in the list.

2.1.3 LAN Configuration in an IPv6 Network

Advanced > IPv6 > IPv6 LAN > IPv6 LAN Config

(1)In IPv6 mode, the LAN DHCP server is enabled by default (similar to IPv4 mode). The DHCPv6 server will serve IPv6 addresses from configured address pools with the IPv6 Prefix Length assigned to the LAN.

 IPv4 / IPv6 mode must be enabled in the Advanced > IPv6 > IP mode to enable IPv6 configuration options.

LAN Settings

The default IPv6 LAN address for the router is fec0::1. You can change this 128 bit IPv6 address based on your network requirements. The other field that defines the LAN settings for the router is the prefix length. The IPv6 network (subnet) is identified by the initial bits of the address called the prefix. By default this is 64 bits long. All hosts in the network have common initial bits for their IPv6 address; the number of common initial bits in the network’s addresses is set by the pr efix length field.

Unified Services Router	User Manual

Figure 4: IPv6 LAN and DHCPv6 configuration

Unified Services Router	User Manual

As with an IPv4 LAN network, the router has a DHCPv6 server. If enabled, the router assigns an IP address within the specified range plus additional specified information to any LAN PC that requests DHCP served addresses.

The following settings are used to configure the DHCPv6 server:

DHCP Mode: The IPv6 DHCP server is either stateless or stateful. If stateless is selected an external IPv6 DHCP server is not required as the IPv6 LAN hosts are auto-configured by this router. In this case the router advertisement daemon (RADVD) must be configured on this device and I CMPv6 router discovery messages are used by the host for auto -configuration. There are no managed addresses to serve the LAN nodes. If stateful is selected the IPv6 LAN host will rely on an external DHCPv6 server to provide required configuration settings

The domain name of the DHCPv6 server is an optional setting

Server Preference is used to indicate the preference level of this DHCP server. DHCP advertise messages with the highest server preference value to a LAN host are preferred over other DHCP server advertise messages. The default is 255.

The DNS server details can be manually entered here (primary/secondary options. An alternative is to allow the LAN DHCP client to receive the DNS server details from the ISP directly. By selecting Use DNS proxy, this router acts as a proxy for all DNS requests and communicates with the ISP’s DNS servers (a WAN configuration parameter).

Primary and Secondary DNS servers: If there is configured domain name system (DNS) servers available on the LAN enter the IP addresses here.

Lease/Rebind time sets the duration of the DHCPv6 lease from this router to the LAN client.

IPv6 Address Pools

This feature allows you to define the IPv6 delegation prefix for a range of IP addresses to be served by the gateway’s DHCPv6 server . Using a delegation prefix you can automate the process of informing other networking equipment on the LAN of DHCP information specific for the assigned prefix.

Prefix Delegation

The following settings are used to configure the Prefix Delegation:

Prefix Delegation: Select this option to enable prefix delegation in DHCPv6 server. This option can be selected only in Stateless Address Auto Configuration mode of DHCPv6 server.

Unified Services Router	User Manual

Prefix Address: IPv6 prefix address in the DHCPv6 server prefix pool

Prefix Length: Length prefix address

2.1.4Configuring IPv6 Router Advertisements

Router Advertisements are analogous to IPv4 DHCP assignments for LAN clients, in that the router will assign an IP address and supporting network information to devices that are configured to accept s uch details. Router Advertisement is required in an IPv6 network is required for stateless auto configuration of the IPv6 LAN. By configuring the Router Advertisement Daemon on this router, the DSR will listen on the LAN for router solicitations and respond to these LAN hosts with router advisements.

RADVD

Advanced > IPv6 > IPv6 LAN > Router Advertisement

To support stateless IPv6 auto configuration on the LAN, set the RADVD status to Enable. The following settings are used to configure RADVD:

Advertise Mode: Select Unsolicited Multicast to send router advertisements

(RA’s) to all interfaces in the multicast group. To restrict RA’s to wellknown IPv6 addresses on the LAN, and thereby reduce overall network traffic, select Unicast only.

Advertise Interval: When advertisements are unsolicited multicast packets, this interval sets the maximum time between advertisements from the interface. The actual duration between advertisements is a random value between one third of this field and this field. The default is 30 seconds.

RA Flags: The router advertisements (RA’s) can be sent with one or both of these flags. Chose Managed to use the administered /stateful protocol for address auto configuration. If the Other flag is selected the host uses administered/stateful protocol for non-address auto configuration.

Router Preference: this low/medium/high parameter determines the preference associated with the RADVD process of the router. This is useful if there are other RADVD enabled devices on the LAN as it helps avoid conflicts for IPv6 clients.

MTU: The router advertisement will set this maximum transmission unit (MTU) value for all nodes in the LAN that are auto configured by the router. The default is 1500.

Router Lifetime: This value is present in RA’s and indicates the usefulness of this router as a default router for the interface. The default is 3600

Unified Services Router	User Manual

seconds. Upon expiration of this value, a new RADVD exchange must take

place between the host and this router.

Figure 5: Configuring the Router Advertisement Daemon

Advertisement Prefixes

Advanced > IPv6 > IPv6 LAN > Advertisement Prefixes

The router advertisements configured with advertisement prefixes allow this router to inform hosts how to perform stateless address auto configuration. Router advertisements contain a list of subnet prefixes that allow the router to determine neighbours and whether the host is on the same link as the router .

The following prefix options are available for the router advertisements:

IPv6 Prefix Type: To ensure hosts support IPv6 to IPv4 tunnel select the 6to4 prefix type. Selecting Global/Local/ISATAP will allow the nodes to support all other IPv6 routing options

SLA ID: The SLA ID (Site-Level Aggregation Identifier) is available when 6to4 Prefixes are selected. This should be the interface ID of the router’s

LAN interface used for router advertisements.

Unified Services Router	User Manual

IPv6 Prefix: When using Global/Local/ISATAP prefixes, this field is used to define the IPv6 network advertised by this router.

IPv6 Prefix Length: This value indicates the number contiguous, higher order bits of the IPv6 address that define up the network portion of the address. Typically this is 64.

Prefix Lifetime: This defines the duration (in seconds) that the requesting node is allowed to use the advertised prefix. It is analogous to DHCP lease time in an IPv4 network.

Figure 6: IPv6 Advertisement Prefix settings

2.2 VLAN Configuration

The router supports virtual network isolation on the LAN with the use of VLANs. LAN devices can be configured to communicate in a sub network defined by VLAN identifiers. LAN ports can be assigned unique VLAN IDs so that traffic to and from that physical port can be isolated from the general LAN. VLAN filtering is particularly useful to limit broadcast packets of a device in a large network

VLAN support is disabled by default in the router. In the VLAN Configuration page, enable VLAN support on the router and then proceed to the next section to define the virtual network.

Setup > VLAN Settings > Available VLAN

The Available VLAN page shows a list of configured VLANs by name and VLAN ID. A VLAN membership can be created by clicking the Add button below the List of Available VLANs.

A VLAN membership entry consists of a VLAN identifier and the numerical VLAN ID which is assigned to the VLAN membership . The VLAN ID value can be any

Unified Services Router	User Manual

number from 2 to 4091. VLAN ID 1 is reserved for the default VLAN, which is used for untagged frames received on the interface. By enabling Inter VLAN Routing, you will allow traffic from LAN hosts belonging to this VLAN ID to pass through to other configured VLAN IDs that have Inter VLAN Routing enabled.

Figure 7: Adding VLAN memberships to the LAN

2.2.1 Associating VLANs to ports

In order to tag all traffic through a specific LAN port with a VLAN ID, you can associate a VLAN to a physical port.

Setup > VLAN Settings > Port VLAN

VLAN membership properties for the LAN and wireless LAN are listed on this page. The VLAN Port table displays the port identifier, the mode setting for that port and VLAN membership information. The configuration page is accessed by selecting one of the four physical ports or a configured access point and clicking Edit.

The edit page offers the following configuration options:

Mode: The mode of this VLAN can be General, Access, or Trunk. The default is access.

In General mode the port is a member of a user selectable set of VLANs. The port sends and receives data that is tagged or untagged with a VLAN ID. If the data into the port is untagged, it is assigned the defined PVID. In the configuration from Figure 4, Port 3 is a General port with PVID 3, so untagged data into Port 3 will be assigned PVID 3. All tagged data sent out of the port with the same PVID will be untagged. This is mode is typically used with IP Phones that have dual Ethernet ports. Data coming from phone to the switch port on the router will be tagged. Data passing through the phone from a connected device will be untagged.

Unified Services Router	User Manual

Figure 8: Port VLAN list

In Access mode the port is a member of a single VLAN (and only one). All data going into and out of the port is untagged. Traffic through a port in access mode looks like any other Ethernet frame.

In Trunk mode the port is a member of a user selectable set of VLANs. All data going into and out of the port is tagged. Untagged coming into the port is not forwarded, except for the default VLAN with PVID=1, which is untagged. Trunk ports multiplex traffic for multiple VLANs over the same physical link.

Select PVID for the port when the General mode is selected.

Configured VLAN memberships will be displayed on the VLAN

Membership Configuration for the port. By selecting one more VLAN membership options for a General or Trunk port, traffic can be route d between the selected VLAN membership IDs

2.2.2 Multiple VLAN Subnets

Setup > VLAN Settings > Multi VLAN Settings

This page shows a list of available multi -VLAN subnets. Each configured VLAN ID can map directly to a subnet within the LAN. Each LAN port can be assigned a unique IP address and a VLAN specific DHCP server can be configured to assign IP address leases to devices on this VLAN.

VLAN ID: The PVID of the VLAN that will have all member devices be part of the same subnet range.

IP Address: The IP address associated with a port assigned this VLAN ID.

2.3 Configurable Port: DMZ Setup

 DSR-150/150N/250/250N does not have a configurable port – there is no DMZ support.

This router supports one of the physical ports to be configured as a secondary WAN Ethernet port or a dedicated DMZ port. A DMZ is a sub network that is open to the public but behind the firewall. The DMZ adds an additional layer of security to the LAN, as specific services/ports that are exposed to the internet on the DMZ do not have to be exposed on the LAN. It is recommended that hosts that must be exposed to the internet (such as web or email servers) be placed in the DMZ network. Firewall rules can be allowed to permit access specific services/ports to the DMZ from both the LAN or WAN. In the event of an attack to any of the DMZ nodes, the LAN is not necessarily vulnerable as well.

Setup > DMZ Setup > DMZ Setup Configuration

DMZ configuration is identical to the LAN configuration. There are no restrictions on the IP address or subnet assigned to the DMZ port, other than the fact that it cannot be identical to the IP address given to the LAN interface of this gateway.
