1.1. Package Contents

y SP881B Broadband VPN Firewall

y Quick Installation Guide

y Manual CD

y Power Adapter

y RJ-45 Ethernet Cable

1.2. Key Features

y Shared Broadband Internet Access

 All LAN users can access the Internet through the SP881B Firewall Router by a

single Broadband modem and connection.

y Supports all common Connection Methods

 All popular DSL and Cable Modems and connection methods are supported,

including Fixed IP, Dynamic IP, PPPoE, and PPTP.

y PPPoE Session Management

 Multiple PPPoE sessions are supported and users can choose to “map” sessions to

individual PC.

y Multiple IP Address Support

 If ISP allocates user with multiple IP addresses, these are also supported and user

can “map” IP addresses to individual PC.

y Special Applications

 This feature allows user to use some non-standard applications, where the port

number used for the response is different to the port number used by the sender.

y Virtual Servers

 This feature allows Internet users to access Internet servers on LAN. For standard

servers such as Web, FTP or E-Mail servers, only the IP address of the server PC is

required. Users can also define their own server types if required.

y Multiple DMZ

 A "DMZ" PC will receive incoming connection requests, which would otherwise be

blocked. For each IP address allocated by ISP, a separate "DMZ" PC can be

specified. So if your ISP has given you multiple IP addresses, you can have multiple

“DMZ” PCs. Each “DMZ” PC has unrestricted 2-way Internet access, providing the

ability to run programs that are otherwise incompatible with NAT routers like the

SP881B Firewall Router.

y Access Filter

 The network Administrator can use the Access Filter to gain fine control over the

Internet access and applications available to LAN users. Five (5) user groups are

available, and each group can have different access rights.

y URL Filter

 Use this feature to block access to undesirable websites. Users can even have

different settings for different groups of PC.

y Session Limit

 With Session Limit feature, if the numbers of new sessions for system exceed the

maximum in the sampling time, any new session will be drop.

y System Filter Exception

 With System Filter Exception, the packets will not be processed by firewall or NAT

module, but be processed directly by system protocol stack.

y VPN ( Virtual Private Network)

 Support up to 20 VPN tunnels for VPN connection. It also supports IPSec and

PPTP Pass-Through.

there will be error in your setup. Please recheck steps above.

 For each LAN port that is connected, its corresponding LED will light up to indicate

successful connection and traffic for the port.

3.3. IP Configuration

Follow the steps below to configure and set up Broadband Router. A computer with wired Ethernet

connection to the wireless router is required for first time configuration. PC/Notebook must belong in the

same IP range and subnet. Follow the steps below to configure IP settings for LAN PC.

Step 1. In the control panel, double click on Network Connections. Double click on the local area

connection (e.g. LAN). The following screen will appear. Highlight ‘Internet Protocol (TCP/IP)’ and click

on ‘Properties’.

Step 2. Select ‘Obtain an IP address automatically’ and ‘Obtain DNS server address automatically’, then

click <OK>.

Step 3. In DOS command, type ‘ipconfig’ to view information on LAN connection. Ensure the IP address

and subnet mask are on the same subnet as the router.

Default Values

IP Address 192.168.1.1

Subnet Mask 255.255.255.0

Username ‘admin’

Password Leave the password field blank

3.4. Quick Setup

SP881B is embedded with http sever and provides a series of web pages, which display the

configuration and status of the system. After configuration of IP, the management interface can be

access by entering the IP address of the router into the browser.

Step 1. Login page will appear to prompt users to enter the username and password.

Step 2. After correctly entering the login details, the following interface will appear. Please enter new

password details and press <Submit>.

Step 3. Select LAN & DHCP from the menu. Users will see a screen like the example below.

Component Description

LAN IP

Configuration

IP address - for the Load Balancer, as seen from the

local LAN. Use the default value unless the address

is already in use or your LAN is using a different IP

address range. In the latter case, enter an unused IP

Address from within the range used by your LAN.

Subnet Mask - The default value 255.255.255.0 is

standard for small (class "C") networks. For other

networks, use the Subnet Mask for the LAN segment

to which the Load Balancer is attached (the same

value as the PCs on that LAN segment).

Optional

Configuration

LAN Any IP – By default is disabled. If you enable

‘LAN Any IP’, that means you can setup local host IP

(static IP) other than device LAN IP segment, and yet

it still can access Internet through NAT.

Alias LAN – When both enable ‘LAN Any IP’ & ‘Alias

LAN’, the LAN segment will give you maximum 5 sets

of LAN segment.

DHCP

Configuration

DHCP Server Setup - If Enabled, the Load Balancer

will allocate IP Addresses to PCs (DHCP clients) on

your LAN when they start up. The default and

recommended value is ‘Enable’. (Windows systems,

by default, act as DHCP clients. This setting is called

‘Obtain an IP address automatically’.) If you are

already using a DHCP Server, the DHCP Server

setting must be ‘Disabled’. The existing DHCP server

must be set to provide the IP address of the Load

Balancer as the Default Gateway.

Lease Time – It is a finite period of time for a DHCP

server lease an IP address to a client.

DNS Server IP for Client – An IP address of the

default DNS server for the client requesting DHCP

service.

Offered IP Range fields set the values used by the

DHCP server when allocating IP Addresses to DHCP

clients. This range also determines the number of

DHCP clients supported.

DHCP Free List

Free Entry indicates how many DHCP entries are not

currently allocated, and still available. This table

shows the IP addresses which have been allocated

by the DHCP Server function. For each address

which has been allocated, the following information is

shown.

Name – The ‘hostname’ of the PC. In some cases,

this may not be known.

MAC Address – The physical address (network

adapter address) of the PC.

IP Address – The IP address allocated to this PC.

Type – Indicates IP address to be dynamic or static.

Status – If set to ‘Dynamic’, the IP address was

allocated by this DHCP Server. If set to ‘Sniffed’, the

IP address was detected by examining the LAN,

rather than allocated by the DHCP Server. In this

case, the Name is usually not known.

Time Left – The time expired since which IP address

is leased.

Step 4. Enter the WAN connection in the field below. Information like IP details, username and

password can be obtained from ISP. Press <Submit and Reboot> to restart the device.

Component Description

WAN Connection

Check the Connection Type with your ISP, and select

the appropriate option.

Static IP – Select this connection type if your ISP has

provided a Fixed or Static IP address. Then enter the

data into the Address Info fields.

Dynamic IP – Select this if your ISP provides an IP

address automatically when you connect. You can

ignore the Address Info fields.

PPPoE – Select this if your ISP uses this method.

(Usually, your ISP will provide some PPPoE software.

This software is no longer required, and should not

be used.) If this method is selected, you must

complete the PPPoE dialup fields.

PPTP Connection – This is for PPTP users only.

Enter the Username and Password provided by your

ISP. If using PPTP, enable the PPTP Connection

checkbox, and enter the IP address of the PPTP

server. If using the PPTP connection method, select

Static IP or Dynamic IP, as appropriate and according

to the IP address method used by your ISP.

Address Info

This is for Static IP users only. Enter the address

information provided by your ISP. If your ISP

provided multiple IP address, you can use the Multi-

DMZ screen to assign the additional IP addresses.

DNS (Optional for

dynamic IP)

If users are using a Fixed IP address, it is necessary

to enter at least one DNS. If users are using Dynamic

IP or PPPoE, DNS information is optional.

Optional Host name – This is required by some ISPs. If your

ISP provided a Host Name, enter the detail in this

field. Otherwise, leave it as the default value.

Domain name – This is required by some ISPs. If

your ISP provided a Domain Name, enter the detail in

this field. Otherwise, leave it as the default value.

MAC address – Some ISP records your MAC

address (also called "Physical address" or "Network

Adapter address"). If so, you can enter the MAC

address expected by your ISP in this field. Otherwise,

this should be left at the default value.

3.5. Configure User PC

y Ensure your DNS settings are correct.

3.5.3. Linux User

To access the Internet via the SP881B Firewall Router, it is only necessary to set the SP881B Firewall

Router as the "Gateway", and ensure your Name Server settings are correct. Ensure you are logged in

as "root" before attempting any changes.

By default, most UNIX installations use a fixed IP Address. If you wish to continue using a fixed IP

Address, make the following changes to your configuration.

y Set your Default Gateway to the IP Address of the SP881B Firewall Router.

y Ensure your DNS (Name server) settings are correct.

To act as a DHCP Client (recommended), the procedure below may vary according to your version of

Linux and X -windows shell:

y Start your X Windows client.

y Select Control Panel - Network

y Select the "Interface" entry for your Network card. Normally, this will be called "eth0".

y Click the Edit button, set the "protocol" to "DHCP", and save this data.

y To apply your changes

y Use the "Deactivate" and "Activate" buttons, if available.

y Or, restart your system.

3.6. DMZ Port

SP881B Firewall VPN Link Balancer with one hardware DMZ is implemented through the hardware. The

router has a separate hardware Ethernet port for DMZ. Multiple devices with public IP addresses

assigned by the ISP can be connected. Incoming data for these devices from the Internet will be sent by

the router to the hardware Ethernet port directly.

y The DMZ port is a normal port, not an ‘uplink’ port.

y PCs connected to the DMZ port are on the same LAN segment as PCs connected to the

Hub ports. They must use the same IP address range.

y PCs connected to the DMZ port are not visible to PCs on the hub (LAN) ports. So you

cannot use Microsoft networking or other networking protocols to connect to PCs on the

DMZ.

y PCs connected to the DMZ port still share the WAN port IP address for Internet access.

Component Description

DMZ Settings DMZ Port – It use a standard LAN cable to connect a

normal port on the other hub.

Associated Interface – WAN1 port is the hardware

DMZ port associated with.

Access From LAN –The local LAN user can access

DMZ port, if this check-box is been checked.

DMZ Broadcast / Outbound – The device that

connects to DMZ port, their packets can be broadcast

to the Internet. If DMZ “Broadcast / Outbound” is

been enabled.

ARP Table – It is a mechanism for viewing ARP

related information.

4. Web-Based Management Interface

4.1. Host IP Setup

This feature is used in the following situations:

y Users have Multi-Session PPPoE, and wish to bind each session to a particular PC on the

LAN.

y Users wish to use the Access Filter feature. This requires that each PC be identified by

using the Host IP Setup screen.

y Users wish to have different URL Block settings for different PCs. This requires that each

PC be identified by using the Host IP Setup screen. (Users do not have to use the Host IP

feature to apply the same URL Block settings to all PCs.)

y Users wish to reserve a particular (LAN) IP address for a particular PC on your LAN. This

allows the PC to use DHCP (Windows calls this "Obtain an IP address automatically") while

gaining the benefits of a fixed IP address. The PC's IP address will never change, so it can

be provided to other people and applications.

Component Description

Host Network

Identity

Host name (Required) – Enter a suitable name.

Generally, users should use the ‘Hostname’

(computer name) defined on the Host itself.

MAC Address (Required) – Also called Physical
