Virtual Servers

This feature, sometimes called Port Forwarding, allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because:

• Your Server does not have a valid external IP Address.

• Attempts to connect to devices on your LAN are blocked by the firewall in this device.

The "Virtual Server" feature solves these problems and allows Internet users to connect to your servers, as illustrated below.

Figure 51: Virtual Servers

IP Address seen by Internet Users

Note that, in this illustration, both Internet users are connecting to the same IP Address, but using different protocols.

To Internet users, all virtual Servers on your LAN have the same IP Address. This IP Address is allocated by your ISP.

This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers.

However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your Virtual Ser vers using a URL, instead of an IP Address.

Virtual Servers Screen

• The "Virtual Servers" feature allows Internet Users to access PCs on your LAN.

• The PCs must be running the appropriate Server Software.

Advanced Features

• For Internet Users, ALL of your Servers have the sa me IP address. This IP address is

allocated by your ISP.

• To make it easier for Internet users to connect to your Servers, you can use the "DDNS"

feature. This allows Internet users to connect to your Servers with a URL, rather than an IP address. This technology works even if your ISP allocates dynamic IP addresses (IP address is allocated upon connection, so it may change each time you connect).

Data - Virtual Servers Screen

Servers

Servers This lists a number of common Server types. If the desired Server

type is not listed, you can create a Firewall Rule to achieve the same effect as the Virtual Server function.

Properties

Enable Use this to Enable or Disable support for this Server, as required.

If Enabled, you must select the PC to which this traffic will be sent.

PC (Server) Select the PC for this Server. The PC must be running the appr opri-

ate Server software.

For each entry, the PC must be running the appropriate Server software. If the desired Server type is not listed, you can define your own Servers, using the Firewall Rules.

Connecting to the Virtual Servers

Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the Internet IP Address (the IP Address allocated to you by your ISP). e.g.

http://203.70.212.52 ftp://203.70.212.52

It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic. However, you can use the Dynamic DNS feature to allow users to connect to your Virtual Servers using a URL, rather than an IP Address.

802.11g ADSL VoIP Gateway User Guide

Note:

From the Internet, ALL Virtual Servers have the IP Address allocated by your ISP.

Advanced Features

VoIP

To use the VoIP feature requires the following:

• Standard Phone

A standard analogue Phone must be connected to the Phone socket.

• VoIP (SIP Server) Account

Generally, you will need a SIP Server account from a VoIP service provider. The account details should include the SIP Register address, SIP Proxy address, SIP register port, SIP Proxy port, username, password and telephone number. (Many providers use the same proxy server for both Proxy and Register.)

• VoIP Configuration

• Your VoIP service provider may perform the configuration for you.

• If not, refer to the following sections, which describe how to conf igure the Wireless

VoIP Gateway.

Refer to Chapter 7 - Operation and Status for details on using VoIP once configuration has been com pleted.

VoIP Setup Screen

The VoIP setup screen is not on the menu; the VoIP link on the menu displays the VoIP Status screen, described later in this chapter.

To view the VoIP Setup Screen:

1. Connect to the 802.11g ADSL VoIP Gateway using its IP address and the path to the VoIP

Setup screen ( /set_voip.htm ). For example, if the default IP address has not been changed, use the following:

http://192.168.0.1/set_voip.htm

2. You will see the VoIP Settings screen, like the example below. This screen allows input of

the data necessary to establish a connection to the SIP Server. Note that the Line 2 settings are the same as Line 1; only Line 1 is shown below.

Local Service

SIP Local Port This port is used for peer -to-peer (direct) connections to another

device, when no SIP server is used. Normally, this should be left at the default value. Any other devices

you wish to connect to must use the same port number.

SIP - Line 1 & Line 2

Enable Line1 Check this if you wish to connect to a SIP Server. If enabled, you

must provide the following data.

SIP Proxy ad dress Enter the address of the SIP Proxy (Server) used by your VoIP pr o-

vider.

SIP Proxy port Enter the port used for connections to the Server above. SIP register ad-

dress SIP register port Enter the port used for "Register" connections to the Server above. Register

Expiry Time User Name Enter the login name for connections to the SIP Server. Password Enter the password associated with the login name above. Telephone

Number

Display Name This name is used by the SIP Server, and may be visible to cal lers.

Enter the address of the SIP Register (Server) used by your VoIP provider. This may be the same server as the "Proxy" above.

This sets the "Idle Timeout" for the SIP Server Login. An Idle connection will be terminated after this time period. Enter the desired value.

Enter the telephone number provided to you by the VoIP Service provider. If you have a range of numbers, enter the number you wish to use for this line.

VoIP Status Screen

This screen allows you to check the status of the connection to the SIP Server. It is accessed via the VoIP link on the Advanced menu. Status information for each line is shown.

Figure 54: VoIP Status Screen

VoIP Status

Line 1 & Line 2

VoIP Status This indicates if VoIP is enabled or disabled. Line Status Sometimes called "Hook Status"; this indicates the status on the

telephone line. ON indicates the receiver is "on-the-hook", while OFF indicates the receiver is "off-the-hook".

Display Name This is the name you chose when you first opened your account.

Your "Display Name" will be visible to other individuals with caller ID. If your display name appears as "UNAVAILABLE", either your VoIP account has not been established or your router has been unable to connect to the VoIP Server.

Telephone Number The telephone number associated with this line. This is the tel e-

phone number other people will use when they call you. This number was assigned to you when you first established your account. Each line can have a different telephone number.

If this displays "UNAVAILABLE", either your VoIP account has not been established or this device was unable to connect to the SIP server.

Registration Status This shows the status of the connection to the SIP Server. When

your router has successful ly connected, the status will be displayed as "Success".

However, if you do not have VoIP account or if the router could not connect to the VoIP server, the status will be displayed as "Idle".

PSTN Settings Screen

This screen has some additional settings related to the use of the PSTN line, assuming the PSTN line is connected, which is strongly recommended.

Figure 55: PSTN Screen

PSTN Settings

PSTN Relay

PSTN Prefix The PSTN Relay allow certain calls to be diverted to the PSTN link,

even though VoIP is working properly. This PSTN prefix means that any number beginning with this prefix

will be diverted to PSTN (the prefix itself is deleted, then the remainder of the number is dialed via PSTN).

• If the prefix is a single character, that character must be *

• If the prefix is multiple characters, all characters after the 1st

character must be digits. The 1st char character can be * or a digit.

Note: When dialing, do not wait for a 2nd dial tone for the PSTN; there is no 2nd dial tone. Just dial the PSTN prefix and the desired phone number.

PSTN Fixed Relay This provides another method of diverting calls to the PSTN link. Any

Telephone numbers listed in this table will always be dialed via PSTN. This feature should be used to direct emergency numbers to the

PSTN.

PSTN Rollover

Use PSTN… If enabled, then when VoIP is unavailable, all calls from the handset

will be sent via PSTN. (This is the same effect as occurs when the power is off.) However, note that VoIP phone numbers (beginning with are often unreachable via PSTN.

Normally, this setting should be Enabled .
