So you have got your IP block from your ISP, but how to you set up your 5861 to use them all?

Your IP addresses

Your ISP should have advised you of the IP addresses that they have assigned you. If you have asked for 5 static IP's then you will be assigned 8 actual IP addresses (commonly called a /29), these are used with a .248 subnet and are described below:-

If you have been assigned 13 IP's (/28) then 8 are useable (instead of the 5 in our example) and use a .240 subnet.

Connecting Your Router

• Place your router in a location where it will be well ventilated. Do not stack it with other devices on carpet.
• After ensuring that the power switch on the back of the router is switched off, connect the router to an AC power outlet using the power cord.
• Use a straight-through cable (red label) to connect your PC to an Ethernet port on the router. You can also connect up to three additional LAN devices to the built-in Ethernet hub.
• Switch the router power switch on.

If you want to skip the quick explanation of some of the features and terms used while configuring the router just follow the numbered steps and screenshots.

1. Using your web browser, enter the following default router address into the address field of your browser: http://192.168.254.254

2. At the login prompt, make the following entries:

User Name: login
Password: admin

3. After you have logged into your router, a dialog will appear, prompting you to change your password. It is a security risk to leave the password set to the factory default. Therefore, changing the password is strongly recommended. To change the password, click on OK at the prompt.

Router Information Screen

The first screen in the Web User Interface is the Router Configuration screen. This screen displays basic router information and router configuration settings.

It also provides links to other router setup and control forms. On the Router Configuration screen, the following information is presented:

Router Information - Including the model number, software version number and options that have been enabled.

Router Configuration - Displays router configuration details such as LAN IP address, WAN data and voice PVC (ATM) or DCLI (frame relay), WAN protocol and WAN network settings.

A menu of links is on the left side of the Router Configuration screen. This menu links to forms that provide settings for your router. Easy Setup is the first set of forms on the menu.

4. Click on the Easy Setup link to begin a basic configuration of your router.

Easy Setup is a set of web forms designed to facilitate the configuration of your router quickly and easily. Easy Setup is a permanent feature, accessible from any platform with a web browser.

Wide Area Network Configuration

The first Easy Setup screen is for the configuration of Wide Area Network settings. The information on this and subsequent screens is obtained from your Internet Service Provider (ISP).
The first required entry is for the Permanent Virtual Circuit (PVC). The PVC is a logical connection between the router and the ISP. It is described using two numbers; the Virtual Path Identifier (VPI) and the Virtual Channel Identifier (VCI).

5. Enter the PVC and VCI values into the WAN Interface fields as indicated.

6. Select the WAN protocol PPPoA with VC.

Click on the Next button to continue with Easy Setup.

You will see a screen requesting a PPP user name and a PPP password. You should have received this information from your service provider.

7. Enter your user name and password in the fields indicated. Click on the Next button to continue Easy Setup.

8. As options, you can choose Bridging, IP routing and Block NetBIOS traffic.

Click on the Next button to continue with Easy Setup.

Dynamic Host Configuration Protocol

9. You must disable the DHCP server by unticking the checkbox.

10. You can set your router to obtain DNS information automatically. You can also choose to configure DNS manually by making the required entries in the form. If you are configuring DNS manually, you must enter at least one DNS IP address.

Domain Name Service (DNS) maps host names to IP addresses. DNS is performed by Domain Name Servers. The domain name identifies the default name for the network. The Windows Internet Naming Service (WINS) maps NetBIOS names to IP addresses.

Click on the Next button to continue Easy Setup.

LAN IP Configuration

The final screen in Easy Setup is for Local Area Network (LAN) configuration.

11. Enter the IP address into the field provided. The IP address is the network address of your router, this address is the one specified by your ISP.

12. Enter the subnet mask into the field provided. The subnet mask is used along with the IP address to determine if specific LAN IP traffic should be forwarded to the WAN.

13. Click Save and Reboot to save your settings in Easy Setup. Your router will reboot with the new configuration settings.

Setting your PC

For our example we will assume we have been assigned the IP addresses 12.34.56.1 to 12.34.56.8 from our ISP.

Make sure you have installed your network card (NIC) and the necessary drivers.
Because you will not be using the routers DHCP server all the PC's will need to be assigned an IP address. This varies between operating systems, but on most Windows systems it can be found in the Control Panel under Networks/Network Connections.

The TCP/IP settings should be set to include your IP address, subnet, gateway (routers IP) and the DNS servers of your ISP (but you could substitute the routers IP for these if you wish).

Set all your PC's using the IP's assigned.

Beyond Easy Setup, your router is equipped with additional features that can be implemented using the Web interface links found on the Router Information Screen. These features, along with brief descriptions of each, are listed below:

Extra features

• Access Control - The Access Control feature restricts administrative access and control of your router to a select group of hosts.
• Feature Activation - This feature supports the installation of feature activation keys that are used to enable additional features on your router.
• Current Date and Time - This feature enables you to set the date and time on your router.
• Set DHCP - The DHCP feature enables or disables DHCP, and manages your IP address pool.
• Set NAT - This feature enables or disables Network Address Translation between the Local and Wide Area Networks.
• Set Firewall - A simple yet powerful network security feature for the creation and development of firewalls.
• Dial Backup - The Dial Backup feature provides a backup connection to the Internet through an external modem, connected to the console port of your router.
• IKE/IPSec Configuration - This is an optional feature for your router. IKE/IPsec (Internet Key Exchange/Internet ProtocolSecurity) configuration screens enable optional authentication and encryption of IP traffic for the authenticity, integrity and privacy of your communications.

Additional features can be found in by pointing your browser to http://192.168.254.254/tools
