If you arrived directly at this article, the first part of this tutorial can be found here.

The installation and setup of AllegroSurf for use on a network begins the same as a single user installation with one exception. When AllegroSurf prompts you for a disk to create a client browser setup disk, select "Yes." This greatly simplifies the process of configuring your network to work through AllegroSurf.

NOTE: If a setup disk is not created at the time of installation, the option to create one is found in the AllegroSurf folder in the Start Menu under Create Client Computer Setup Diskette.

AllegroSurf must be installed on only the server computer.

Insert the client install disk into the client computer's disk drive and run the file named ASClientSetup.exe. This will configure the computer's browsers to use AllegroSurf on the server computer. This disk will also setup the FTP clients FTP Voyager, CuteFTP, and FTP Explorer and the mail clients Outlook and Outlook Express. Repeat this process for all the other computers on your network. Your network is now configured for use with AllegroSurf.

If you do not have this disk, you must first find what the IP Address is of the computer that AllegroSurf is running on. This can normally be done by selecting Run from the Start menu and running "winipcfg" (Windows 95/98/ME only) or by typing "ipconfig" (Windows 2000 and up) from a command window.

After AllegroSurf is installed and running on the server computer, you are ready to configure the rest of the computers on your network to use AllegroSurf. Begin by changing your Internet connection.

  1. From the Start Menu, select Settings, and open the Control Panel.
  2. Open the Internet Options folder.
  3. Select the Connections tab and click on the LAN Settings button found at the bottom of the dialog box.
  4. Check the box marked "Use Proxy Server." Click on Advanced.
  5. In the HTTP box, enter the IP Address of the server computer running AllegroSurf and the Port number (the Port number can be found in AllegroSurf under Servers | WWW Proxy Server in the box labeled "Accept Connections on this Port").
  6. Check the box labeled "Use the same proxy for all protocols" and click OK.

This computer will now request all web pages from AllegroSurf on the server's computer and will then also take advantage of all of AllegroSurf's features on the Internet.

Be sure that you also change any FTP Clients to use AllegroSurf as their proxy connection to the Internet. The ASClientSetup.exe will also help you in doing this.

In addition, AllegroSurf needs to be configured to use your ISP's mail server. Since AllegroSurf is now your route to the Internet, all requests outside of your network must first go to AllegroSurf.

  1. Open AllegroSurf by double-clicking on its icon in the taskbar.
  2. Select the Proxy Servers menu. AllegroSurf will show you all the protocols that it currently has installed on it. One of these is called POP3 Proxy Server.
  3. Double click on the POP3 Proxy Server and click on the POP3 tab in the window that is opened.
  4. Make sure that "Send non-proxy requests through" is checked and enter your ISP's mail server in the box below it (i.e. "") and the Port number.
  5. Now you must bind this protocol to your network to avoid anyone from attempting to use your mail server from outside AllegroSurf. Go to the Bind tab and click on "Allow connection from ONLY this IP Address." Enter the IP Address of the server's computer in the box. AllegroSurf will only send requests to your mail server that have routed through the server computer.
  6. Repeat steps 3-5 for the SMTP Mapping Proxy Server which is also found under the Proxy Servers menu.

Now that the server is configured, the mail clients on your network's client computers must also be set up to use AllegroSurf in order to collect their mail.

  1. Start your mail client and enter the setup screen where you specify your server names, username, and password.
  2. Change the POP3 and SMTP server names to the IP Address of your AllegroSurf server. Make sure to also change the Port numbers to the corresponding ones you gave AllegroSurf.
  3. Your username must also be modified. At the end of your user name, enter a '#' (the delimiter character specified in the AllegroSurf Proxy Server POP3 Proxy setup) followed by your ISP's mail server (i.e. "").
  4. Apply these changes and continue collecting your mail as usual!

AllegroSurf is a fully customizable proxy server. The settings specified above are just basic settings meant to get you started. To learn more about the possibilities, read the help files provided with AllegroSurf and do some experimenting. Just remember to write down the correct settings in case something doesn't work.
