Configure Wingate 2.0 | ApplicationsWingate 2.0 main |


Note: Wingate version 2.x sometimes drops off line causing the client computers to be unable to access the internet or use email. To fix this, click the START button on the task bar, select Programs, then Wingate 2.1, then Start Wingate Engine. This will restart Wingate and the clients should work as before.

Introduction

Using the Wingate Proxy/Firewall program, a single computer equipped with a modem can be used as a server allowing more than one other computer connected to it through a network to access WWW internet services, email and other programs that communicate using TCP/IP.

Note 1: For proxy servers to work correctly, the computers used must run TCP/IP, and the IP addresses must be close enough to each other so they fall on the same subnet. For example, if you use 192.168.0.1 for the computer running Wingate, you would set the first client computer's IP address to 192.168.0.2 and the next computer to 192.168.0.3 and so on. The number 192.168.0.1 is not what everybody uses. If your internal network lets say is already setup to use IP addresses like 135.2.1.1 for the Wingate computer, then you would use that number as given to you by your network administrator, and of course the other computers on the same sub net would have very similar numbers. In this example the Wingate computer would have the 135.2.1.1 address and another computer using it would have 135.2.1.2. A number close enough to be on the same sub net with the Wingate computer.

Note 2: Only one computer has Wingate installed and all the other computers need ONLY have the browser preferences changed for the proxy to point to the IP address of the Wingate computer. You do NOT need to install anything, not even dial up networking or a modem on the other computers.

Both NT and Windows 95 computers can be used as the proxy server. Additionally the computer acting as the server does NOT have to be used exclusively as the server. The Wingate program can run in the background and the computer can be used as a regular desktop running other applications.

This allows access to the internet through a single modem. None of the other computers connected to the server need to have a modem installed.

 

Background

The Wingate proxy server/firewall is installed on the computer which has the modem and which is to be used as the connection point to the internet. After the program is installed, selected services are configured or added using the Gatekeeper program which is also added at the time the software is installed.

The services are configured as shown below. Most of the settings are accepted in their default configuration and the ones shown in figure 1 below are changed accordingly. After the services are configured, each individual computer needed to connect to the server (and the internet) has the browser and mail applications settings changed to point to the Server running the Wingate software.

 

Figure 1

Note 1: The above IP address (192.168.0.1) was chosen at random and it is the internal network address of the computer running the Wingate program on the local network. If you already have an IP address assigned to the computer running Wingate, then you would substitute that address for the address 192.168.0.1. Also if you want to give the address a name, the name Wingate can be used as long as you arrange to have the hosts lookup name entered.

Note 2: The HTTP/www services are usually defaulted to port 80 but in this case port 81 was chosen to avoid conflicts with competitors running server software such as FrontPage personal server or NT IIS. Likewise the Socks port normally would default to 1080 but 1081 was used to eliminate conflicts with other services. If your system already uses the above ports, you will need to change the port assignment to a different port and make sure you change the port number in both the Wingate proxy server service and the client browser proxy settings.

Setting up

The operation is broken up into two steps. First the computer having the modem (proxy computer) will have Wingate installed and properly configured with the services shown above. Second, the client computers will be configured by changing settings in the browser to have the browser point to the proxy computer. Each of the Wingate services in the proxy computer are changed accordingly to allow proper operation to take place.

The browser needs to have the WWW proxy setting to point to the WWW service of the proxy computer, and the SOCKS proxy setting to point to the proxy server computer's WWW service. Also the mail server's incoming mail POP3 settings are changed to point to the proxy computer's Wingate POP3 service, and the mail's SMTP outgoing mail settings are changed to point to the proxy computer's TCP service.

More detailed instructions will be added to show the screen dumps of each of the above steps.

The details

1. Install and Configure Wingate

Install Wingate by opening explorer, finding the Wingate file and double clicking on the file. After the installation is complete, several new entries will be added to the Start programs popup.

Select Start, Programs, Wingate2.1, Gatekeeper. The Gatekeeper program will start and you will enter a password to gain access. The first time you run Gatekeeper the password will be blank, and you will be required to enter a password.

Gatekeeper is the front end program that allows you to make changes to the Wingate configuration settings.

After gatekeeper is started, you will see on the right half of the screen several entries including the "+ Services". You will click on the + sign in front of Services to open the services listing.

The services POP3 Server, Socks Server, TCP mapping Service, UDP, mapping Service, and WWW proxy Service need to be modified (if they are already on the listing) or installed if they are not on the listing.

To modify the services double click on the service name.

To install a new service, right-click on Services, select New, select Service, and finally click on the service you want to install.

There are two arrows on the right top corner of each service window.

Those arrows are used to scroll the Tabs left and right, since there are more tabs than can be shown on the window.

For each Service, make the entries as shown on each of the services below.

To make changes to a service, click on the + sign in front of services as shown above then double click the name of the service you want to modify.

The following Screens show each of the Service settings that are needed to make the proper connection in Wingate. Links are provided to each screen in order to allow this page to load quicker and conserve internet bandwidth.

The Services

By going into each of the services below and setting up all of them as shown, you will give the server the ability to perform the internet browser operations, mail operations, and ICQ connections.

In order to have browser, mail and ICQ functions, all the services shown below must be setup. Click on each link and look at the sample screen dumps. (you can make it easy on yourself by printing each one to have as a reference).

POP3 Server
Socks Server
TCP mapping Service
UDP mapping Service
WWW proxy Service

 

2. Modify the browser

The browser is modified to allow it to make the internet connection through the Wingate proxy program.

Netscape Navigator.

Select Option, Network Preferences, Proxies
Click on "Manual Proxy configuration" then click on the "View" button

The settings: On the white text box labeled "HTTP proxy" enter the IP address of the proxy server (i.e. 192.168.0.1) and on the Port to the right enter 81.

On the white text box labeled "Socks Host" enter the IP address of the proxy server (i.e. 192.168.0.1) and to the right in the Port box enter 1081.

Click OK twice to close the windows

Then, select Options "Mail and News preferences", the preferences window will open.

In the "Outgoing Mail (SMTP) Server: box type 192.168.0.1 ( this is the IP address of the Wingate computer)

In the "incoming Mail (POP3) Server" box type 192.168.0.1 ( this is the IP address of the Wingate computer)

In the "POP3 User Name" type in your email address as "yourlogin@yourISP.net"

Navigator will now work through the proxy server. Of course the Wingate computer has to be connected to the internet and the Wingate services must be running.

Netscape Communicator,

Modify The Proxy Settings ...as shown in the The Proxy modifications example

The IP address you use in the proxy configuration is the IP address of the computer where Wingate is running.

Modify the Mail Settings

Select Preferences, Edit, click on the + sign in front of "Mail and Groups" click on Mail Server and enter in the "outgoing mail SMTP server" and the "Incoming Mail server" the IP address of the Wingate computer (i.e. 192.168.0.1). The address you use is the IP address of the computer where Wingate is running. The user information stays the same.

Internet Explorer 3.x

Select View, Options, and click on the Connection Tab.

on the HTTP text box enter the Wingate IP address (i.e. 192.168.0.1) and port 81. In the Socks text box enter the same address as above and Port 1081. Click OK to continue.

For the mail part, Open the mail reader.

Select Mail from the top menu and Options from the pop down menu

Click on the Server tab

Enter your email address in the "Email address" text box

Enter the Wingate computer's IP address (192.168.0.1) in the text boxes "Outgoing Mail (SMTP)" and "Incoming Mail (POP3)".

Click OK to finish the setup.

If there are problems you can check the section Troubleshooting the installation.

Note: Do not forget to Select in the Wingate window, "File", "Save Changes" after you are done. Wingate does NOT save your changes and when you close Wingate they will all be gone if you do not save them.
