ADSL2+ Gateway with VoIP

Chapter 1: Introduction

Welcome

Thank you for choosing the AG310 ADSL2+ Gateway with VoIP. This Gateway will provide your computers with a high-speed Internet connection as well as access to local resources, including files and printers.

How does the Gateway do all of this? By connecting the Internet, as well as your computers and peripherals, to the Gateway, you create a LAN, or Local Area Network. The Gateway lets devices on the network communicate with each other, and it can direct and control communications for your network.

To protect your data and privacy, the Gateway features an advanced firewall to keep out Internet intruders.

Sensitive communications can be protected by powerful data encryption. In addition, you can safeguard your family with parental control features such as Internet access restrictions and keyword blocking. You can configure the Gateway’s settings through the easy-to-use, browser-based utility.

But what does all of this mean?

Networks are useful tools for sharing Internet access and computer resources. You can access one printer from different computers and access data located on another computer’s hard drive. Networks are even used for playing multiplayer video games. So, networks not only are useful in homes and offices, but also can be fun.

With your PCs and peripherals all connected to each other and to the Internet, you can now share files and

Internet access—and even play games. All the while, the ADSL Gateway protects your network from unauthorized and unwelcome users.

Linksys recommends using the Setup CD-ROM for first-time installation of the Gateway. If you do not wish to run the Setup Wizard on the Setup CD-ROM, then use the instructions in this Guide to help you connect the Gateway, set it up, and configure it to bridge your network and the Internet. These instructions should be all you need to get the most out of the ADSL Gateway.

ADSL2+ Gateway with VoIP

Chapter 2: Planning Your Network

The Gateway’s Functions

A Gateway is a network device that connects two networks together.

In this instance, the Gateway connects your Local Area Network (LAN), or the group of computers in your home or office, to the Internet. The Gateway processes and regulates the data that travels between these two networks.

The Gateway’s NAT feature protects your network of computers so users on the public, Internet side cannot “see” your computers. This is how your network remains private. The Gateway protects your network by inspecting every packet coming in through the Internet port before delivery to the appropriate computer on your network.

The Gateway inspects Internet port services like the web server, ftp server, or other Internet applications, and, if allowed, it will forward the packet to the appropriate computer on the LAN side.

Remember that the Gateway’s ports connect to two sides. The LAN ports connect to the LAN, and the ADSL port connects to the Internet. The LAN ports transmit data at 10/100Mbps.

IP Addresses

What’s an IP Address?

IP stands for Internet Protocol. Every device on an IP-based network, including computers, print servers, and

Gateways, requires an IP address to identify its “location,” or address, on the network. This applies to both the

Internet and LAN connections. There are two ways of assigning an IP address to your network devices. You can assign static IP addresses or use the Gateway to assign IP addresses dynamically.

Static IP Addresses

A static IP address is a fixed IP address that you assign manually to a computer or other device on the network.

Since a static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will always have that same IP address until you change it. Static IP addresses must be unique and are commonly used with network devices such as server computers or print servers.

Chapter 2: Planning Your Network

The Gateway’s Functions

Figure 2-1: Network

ip (internet protocol): a protocol used to send data over a network

NOTE: Since the Gateway is a device that connects two networks, it needs two IP addresses—one for the LAN, and one for the Internet. In this User Guide, you’ll see references to the “Internet IP address” and the “LAN IP address.”

Since the Gateway uses NAT technology, the only IP address that can be seen from the Internet for your network is the Gateway’s Internet IP address.

However, even this Internet IP address can be blocked, so that the Gateway and network seem invisible to the Internet—see the Block WAN

Requests description under Security in “Chapter 6:

Configuring the ADSL2+ Gateway.”

3

ADSL2+ Gateway with VoIP

Since you use the Gateway to share your DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the

Gateway. You can get that information from your ISP.

Dynamic IP Addresses

A dynamic IP address is automatically assigned to a device on the network, such as computers and print servers.

These IP addresses are called “dynamic” because they are only temporarily assigned to the computer or device.

After a certain time period, they expire and may change. If a computer logs onto the network (or the Internet) and its dynamic IP address has expired, the DHCP server will automatically assign it a new dynamic IP address.

DHCP (Dynamic Host Configuration Protocol) Servers

Computers and other network devices using dynamic IP addressing are assigned a new IP address by a DHCP server. The computer or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network.

A DHCP server can either be a designated computer on the network or another network device, such as the

Gateway. By default, the Gateway’s DHCP Server function is enabled.

If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the Gateway, see the DHCP section in “Chapter 6: Configuring the ADSL2+

Gateway.”

Phone

The DSL port connects to the ADSL line from your telephone wall jack.

The Line port connects your standard telephone and converts the signal to VoIP technology.

The Phone port connects to an analog phone (or fax machine) with an RJ-11 telephone cable. The primary purpose of this port is to allow a phone to be connected that will function during power outages, in case of an emergency.

Ethernet (1-4) The Ethernet ports connect to your computers and other network devices.

Reset Button There are two ways to reset the Gateway's factory defaults. Either press the Reset Button, for approximately ten seconds, or restore the defaults from the Factory Defaults screen of the

Administration tab in the Gateway’s web-based utility.

Power The Power port is where you will connect the power adapter.

IMPORTANT: Resetting the Gateway to factory defaults will erase all of your settings

(including Internet connection and other settings) and replace them with the factory defaults. Do not reset the Gateway if you want to retain these settings.

Chapter 4: Connecting the ADSL2+ Gateway with VoIP

Overview

The installation technician from your ISP should have left the setup information for the modem with you after installing your broadband connection. If not, you can call your ISP to request that data.

After you have the setup information you need for your specific type of Internet connection, you can begin installation and setup of the Gateway. Continue to “Connecting the Gateway to a Computer.”

Connecting the Gateway to a Computer

1. Make sure that all of your network’s hardware is powered off, including the Gateway and all computers.

2. Connect a phone cable from the DSL port on the Gateway’s back panel to the wall jack of the ADSL line. A small device called a microfilter (not included) may be necessary between each phone and wall jack to prevent interference. Contact your ISP if you have any questions.

3. Connect another phone cable from the Line port on the Gateway’s back panel to the Voice connection on the

DSL microfilter or wall jack.

NOTE: A small device called a microfilter (not included) may be necessary between each phone and wall jack to prevent interference. Contact your ISP if you have any questions.

IMPORTANT: For countries that have phone jacks with RJ-11 connectors, make sure to only place the microfilters between the phone and the wall jack and not between the Gateway and the wall jack or your ADSL will not connect.

For countries that do not have phone jacks with RJ-11 connectors (e.g. France, Sweden,

Switzerland, United Kingdom, etc.), except for ISDN users, the microfilter has to be used between the Gateway and the wall jack, because the microfilter will have the RJ-11 connector.

Annex B users (E1 and DE versions of the Gateway) must use the included special cable to connect the Gateway to the wall jack (RJ-45 to RJ-12). If you require splitters or special jacks, please contact your service provider.

Dynamic Routing

With Dynamic Routing you can enable the Gateway to automatically adjust to physical changes in the network’s layout. Using RIP, the Gateway determines the network packets’ route based on the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing information to other

Gateways on the network.

RIP. If you have multiple routers, you may want to use the Routing Information Protocol (RIP) so the routers can exchange routing information with each other. To use RIP, select the Enabled option. Otherwise, keep the default,

Disabled.

Transmit RIP Version. To transmit RIP messages, select the protocol you want: RIP1, RIP1-Compatible (RIP1

broadcasts and RIP2 multicasts), or RIP2. If you don’t want to transmit RIP messages, select None.

Receive RIP Version. To receive RIP messages, select the protocol you want: RIP1 or RIP2. If you don’t want to receive RIP messages, select None.

Static Routing

If the Gateway is connected to more than one network, it may be necessary to set up a static route between them. A static route is a pre-determined pathway that network information must travel to reach a specific host or network. To create a static route, change the following settings:

Select set number. Select the number of the static route from the drop-down menu. The Gateway supports up to

20 static route entries. If you need to delete a route, then select the entry and click the Delete This Entry button.

ADSL2+ Gateway with VoIP

Tunnel Name: Click and type in this box to give the selected tunnel a name. A name is required, but is only for your reference and need not match the name used at the remote gateway or client.

Local Secure Group: To give an entire local network access to the tunnel, select Subnet and enter the network address and mask. To give a particular host access to the tunnel, select IP Address and enter the host’s address and mask.

Local Security Gateway: If you have multiple PVCs, open this list and select the PVC you wish to use for the VPN tunnel.

Remote Secure Group: Use this control to specify the remote device or devices that will be granted access to the tunnel. This can be the public IP address of a network or host; the IP address and mask of a remote subnet;

Host, that is, identical to the Remote Security Gateway setting; or Any, which allows any device with permission from the remote security gateway to access the tunnel.

Remote Security Gateway: Use the controls in this section to specify the remote endpoint of the IPSec tunnel, whether it will be a gateway or a client. Select IP Address or FQDN (fully qualified domain name) and input the correct address or name; or select Any, which allows any machine with the correct IPSec settings to act as the remote endpoint of the tunnel.

Encryption: To have communication through the tunnel encrypted, select DES (Data Encryption Standard) or 3DES (Triple DES). To leave communication unencryped, select Disable.

Authentication: Authentication verifies the identity of the remote machine and the integrity of the data received. Set this control to MD5 (Message Digest 5) or SHA (Secure Hash Algorithm). SHA is newer, and generally considered more secure, than MD5.

Key Management: A key is a string of letters and/or numbers that is used for authentication or encryption. Key management can be automatic (performed by IKE, the Internet Key Exchange protocol) or manual.

To use automatic key management, select Auto.(IKE), enter the pre-shared key and the key lifetime, and enable or disable PFS (perfect forward secrecy). The key should be a string of 8 to 23 characters representing no dictionary word or numeric pattern. PFS enhances security by enabling automatic re-keying. The settings must exactly match those at the remote end of the tunnel.

To use manual key management, select Manual, enter authentication and encryption keys (these must be identical to those entered at the remote end), and enter inbound and outbound SPIs (security parameter indexes). The SPIs must be exactly complementary to those entered at the remote end.

When you select automatic key management, an Advanced Settings button appears. Click this button if there are special requirements for this IPSec tunnel. The Advanced IPSec VPN Tunnel Setup window will appear. (Help for this window can be displayed by clicking More on the right side of the VPN panel.)

In this window you can set parameters for IKE phases 1 and 2, and other settings. Phase 1 is when the two ends negotiate parameters for key exchange; phase 2 is when they negotiate parameters for data exchange.

Operation mode: Key exchange parameters can be negotiated in Main mode, which is more secure, or

Aggressive mode, which is quicker. The Gateway will accept requests in either mode, but some gateways and clients will accept requests only in the mode specified by the user.

Proposal 1: A proposal is a set of parameters that the initiator sends and the responder examines for acceptability. You can specify encryption and authentication algorithms, Diffie-Hellman group, and key lifetime for the first proposal.

Phase 2 Proposal: Select the desired Diffie-Hellman group, 768-bit or 1024-bit.

• Other Settings

NAT Traversal: Enable this feature if the machine or machines being accessed through the tunnel stand behind a NAT (Network Address Translation) server.

NetBIOS broadcast: Enable this feature if the local network does not include a WINS server and the remote machine or machines will need to find local machines by their NetBIOS (Windows Networking) names.

Anti-replay: Packets sent through an IPSec tunnel contain sequencing numbers to let the receiver detect if a substitution has occurred. You can enable this function for greater security.

Keep-alive: This feature, enabled by default, makes the Gateway check the tunnel connection periodically and attempt to re-establish it if it goes down.

If IKE failed . . . : IKE failure may signify an unwanted intrusion attempt. You can set a limit on the number of consecutive failed requests that the Gateway will allow from the same IP address, and the amount of time that the Gateway will ignore further requests from that address.

When finished making changes in this panel, click the Save Settings button to save your changes, or click

Appendix A: Troubleshooting

This appendix consists of two parts: “Common Problems and Solutions” and “Frequently Asked Questions.”

Provided are possible solutions to problems that may occur during the installation and operation of the Gateway.

Read the descriptions below to help you solve your problems. If you can’t find an answer here, check the Linksys international website at www.linksys.com/international.

Common Problems and Solutions

1. I don’t hear a dial tone, and the PHONE LED is not lit.

Go through this checklist until your problem is solved:

• Make sure the telephone is plugged into the PHONE port.

• Disconnect and re-connect the RJ-11 telephone cable between the Gateway and telephone.

• Make sure your telephone is set to its tone setting (not pulse).

• Make sure your network has an active Internet connection. Try to access the Internet. If you do not have a connection, power off your network devices, including the Gateway and cable/DSL modem. Wait

30 seconds, and power on the cable/DSL modem first. Then power on the Gateway and other network devices.

• Verify your account information and confirm that the phone line is registered with your ITSP.

1. I’m trying to access the Gateway’s web-based utility, but I do not see the login screen. Instead, I see a screen saying, “404 Forbidden.”

If you are using Windows Explorer, perform the following steps until you see the web-based utility’s login screen (Netscape Navigator will require similar steps):

A. Click File. Make sure Work Offline is NOT checked.

B. Press CTRL + F5. This is a hard refresh, which will force Windows Explorer to load new webpages, not cached ones.

C. Click Tools. Click Internet Options. Click the Security tab. Click the Default level button. Make sure the security level is Medium or lower. Then click the OK button.

2. I need to set a static IP address on a PC.

The Gateway, by default, assigns an IP address range of 192.168.1.100 to 192.168.1.150 using the DHCP server on the Gateway. To set a static IP address, you can only use the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to 192.168.1.254. Each PC or network device that uses TCP/IP must have a unique address to identify itself in a network. If the IP address is not unique to a network, Windows will generate an IP conflict error message. You can assign a static IP address to a PC by performing the following steps:

7. I need to set up online game hosting or use other Internet applications.

If you want to play online games or use Internet applications, most will work without port forwarding or DMZ hosting. There may be cases when you want to host an online game or Internet application. This would require you to set up the Gateway to deliver incoming packets or data to a specific computer. This also applies to the Internet applications you are using. The best way to get the information on what port services to use is to go to the website of the online game or application you want to use. Follow these steps to set up online game hosting or use a certain Internet application:

A. Access the Gateway’s web-based utility by going to http://192.168.1.1 or the IP address of the Gateway.

Go to the Router > Application tab.

B. Select yes from the Enable drop-down menu.

C. Enter any name you want to use for the service.

D. Enter the port range of the service you are using. For example, if you have a web server, you would enter the range 80 (in the Starting Port field) to 80 (in the Ending Port field).

E. Select the protocol you will be using, TCP or UDP, or select Both.

F. Enter the IP address of the PC or network device that you want the port server to go to. For example, if the web server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided.

Check “Appendix B: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting an IP address.

8. I can’t get the Internet game, server, or application to work.

If you are having difficulties getting any Internet game, server, or application to function properly, consider exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an application requires too many ports or when you are not sure which port services to use. Make sure you disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority over DMZ hosting. (In other words, data that enters the Gateway will be checked first by the forwarding settings. If the port number that the data enters from does not have port forwarding, then the Gateway will send the data to whichever PC or network device you set for DMZ hosting.) Follow these steps to set DMZ hosting:

A. Access the Gateway’s web-based utility by going to http://192.168.1.1 or the IP address of the Gateway.

Go to the Router > Application tab.

B. Disable or remove the entries you have entered for forwarding. Keep this information in case you want to use it at a later time.

C. Select yes from the Enable DMZ drop-down menu.

D. Enter the Ethernet adapter’s IP address of the computer you want exposed to the Internet. This will bypass the NAT security for that computer. Please refer to “Appendix B: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting an IP address.

Once completed with the configuration, click the Submit All Changes button.

9. I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window.

If you have proxy settings, you need to disable these on your computer. Because the Gateway is the gateway for the Internet connection, the computer does not need any proxy settings to gain access. Please follow these directions to verify that you do not have any proxy settings and that the browser you use is set to connect directly to the LAN.

For Microsoft Internet Explorer 5.0 or higher:

A. Click Start, Settings, and Control Panel. Double-click Internet Options.

B. Click the Connections tab.

C. Click the LAN settings button and remove anything that is checked.

D. Click the OK button to go back to the previous screen.

E. Click the option Never dial a connection. This will remove any dial-up pop-ups for PPPoE users.

For Netscape 4.7 or higher:

A. Start Netscape Navigator, and click Edit, Preferences, Advanced, and Proxies.

B. Make sure you have Direct connection to the Internet selected on this screen.

C. Close all the windows to finish.

Frequently Asked Questions

Can I make calls if my Internet connection is down?

When you make Internet phone calls, your high-speed Internet connection must be active. However, you can make calls using your landline.

Can I make calls while I’m browsing the Internet?

Yes. You can make calls while browsing the Internet. However, your web browsing may affect the quality of your

Internet calls, depending on the amount of upstream data traffic passing through your Internet connection.

What is the maximum number of IP addresses that the Gateway will support?

The Gateway will support up to 253 IP addresses.

Where is the Gateway installed on the network?

In a typical environment, the Gateway is installed between the cable/DSL modem and the local area network

(LAN). Plug the Gateway into the cable/DSL modem’s Ethernet port.

What is Network Address Translation and what is it used for?

Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the Gateway to be used with low cost Internet accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP. The user may have many private addresses behind this single address provided by the ISP.

Does the Gateway support any operating system other than Windows 2000 or XP?

Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of any non-Windows operating systems.

Is IPSec Passthrough supported by the Gateway?

Yes, it is a built-in feature that is enabled by default.

Appendix A: Troubleshooting

Frequently Asked Questions

60

ADSL2+ Gateway with VoIP

Does the LAN connection of the Gateway support 100Mbps Ethernet?

The Gateway supports 100Mbps over the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the

Gateway.

Does the Gateway support ICQ send file?

Yes, with the following fix: click ICQ menu > preference > connections tab>, and check I am behind a

firewall or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then send a file to a user behind the Gateway.

I set up an Unreal Tournament Server, but others on the LAN cannot join. What do I need to do?

If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the LAN computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You can also use a port forwarding range of 7777 to 27900. If you want to use the UT Server Admin, forward another port

(8080 usually works well but is used for remote admin. You may have to disable this.), and then in the

[UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to match the mapped port above) and

ServerName to the IP assigned to the Gateway from your ISP.

Can multiple gamers on the LAN get on one game server and play simultaneously with just one public IP address?

It depends on which network game or what kind of game server you are using. For example, Unreal Tournament supports multi-login with one public IP.

How will I be notified of new Gateway firmware upgrades?

All Linksys firmware upgrades are posted on the Linksys international website at www.linksys.com/international, where they can be downloaded for free. To upgrade the Gateway’s firmware, use the Administration tab of the

Gateway’s web-based utility. If the Gateway’s Internet connection is working well, there is no need to download a newer firmware version, unless that version contains new features that you would like to use.

Does the Gateway pass PPTP packets or actively route PPTP sessions?

The Gateway allows PPTP packets to pass through.

How many ports can be simultaneously forwarded?

Theoretically, the Gateway can establish 520 sessions at the same time, but you can only forward 10 ranges of ports.

What is the maximum number of VPN sessions allowed by the Gateway?

The maximum number depends on many factors. At least one IPSec session will work through the Gateway; however, simultaneous IPSec sessions may be possible, depending on the specifics of your VPNs.

Appendix A: Troubleshooting

Frequently Asked Questions

61

ADSL2+ Gateway with VoIP

How can I check whether I have static or DHCP IP Addresses?

Consult your ISP to obtain this information.

Can the Gateway act as my DHCP server?

Yes. The Gateway has DHCP server software built-in.

What is a MAC Address?

The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level. For all practical purposes, this number is usually permanent. Unlike IP addresses, which can change every time a computer logs onto the network, the MAC address of a device stays the same, making it a valuable identifier for the network.

How do I get Half-Life: Team Fortress to work with the Gateway?

The default client port for Half-Life is 27005. The computers on your LAN need to have “+clientport 2700x” added to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect to the same server. One problem: Version 1.0.1.6 won’t let multiple computers with the same CD key connect at the same time, even if on the same LAN (not a problem with 1.0.1.3). As far as hosting games, the HL server does not need to be in the DMZ. Just forward port 27015 to the local IP address of the server computer.

How can I block corrupted FTP downloads?

If you are experiencing corrupted files when you download a file with your FTP client, try using another FTP program.

The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the screen. What do I need to do?

Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate” feature of your

Ethernet adapter as a temporary measure. (Please look at the Network Control Panel in your Ethernet adapter’s

Advanced Properties tab.) Make sure that your proxy setting is disabled in the browser. Check our website at

www.linksys.com for more information.

Will the Gateway function in a Macintosh environment?

Yes, but the Gateway’s setup pages are accessible only through Internet Explorer 5.0 or Netscape Navigator 5.0 or higher for Macintosh.

What is DMZ Hosting?

Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the Internet. Some applications require multiple TCP/IP ports to be open. It is recommended that you set your computer with a static IP if you want to use DMZ Hosting. To get the LAN IP address, see “Appendix B: Finding the MAC Address and IP Address for Your Ethernet Adapter.”

If DMZ Hosting is used, does the exposed user share the public IP with the Gateway?

No.

Is the Gateway cross-platform compatible?

Any platform that supports Ethernet and TCP/IP is compatible with the Gateway.

Does the Gateway replace a modem? Is there a cable or DSL modem in the Gateway?

No, this version of the Gateway must work in conjunction with a cable or DSL modem.

Which modems are compatible with the Gateway?

The Gateway is compatible with virtually any cable or DSL modem that supports Ethernet.

How do I get mIRC to work with the Gateway?
