ARCHIVED: In Mac OS at IUB, how do I make a VPN connection to the IU wireless network?

Note: This document does not pertain to Mac OS X. For Mac OS X instructions, see the Knowledge Base document In Mac OS X, how do I make a VPN connection to the IU network?

In Mac OS, to use the wireless network at Indiana University Bloomington, you must first authenticate to the virtual private network (VPN) server. This requires NTS TunnelBuilder, a commercial product for VPN. This software is available on CD from the Computer Connection for $30. When you ask for the CD, specify that you need to use VPN for Mac OS 9 and earlier. There is another VPN CD that costs just $5, but it doesn't have the TunnelBuilder software.

To install and configure TunnelBuilder, put the CD in your computer, then follow these instructions:

Note: The following instructions assume you have an AirPort card to connect to the wireless network.

  1. From the CD, double-click TunnelBuilder IUB Installer, and in the dialog box that appears, click Continue... .

  2. Read the license agreement, then click Accept.

  3. In the TunnelBuilder IUB Installer window, click Install. The installer will put the TunnelBuilder software on your computer. When it is finished, click the Restart button.

  4. Once your computer has finished restarting, the Wireless Configuration Assistant will appear. Click Proceed. When the Assistant finishes configuring your software, click OK.

  5. From the Apple menu, choose Control Panels, then select LAN TunnelBuilder Settings.

  6. In the LAN TunnelBuilder (IUB-Wireless-VPN) window, next to "VPN Username:" and "VPN Password:", enter your IU ADS username and password.

  7. From the File menu, select Save Configuration.

Once you have configured TunnelBuilder, to connect to the wireless network, open the LAN TunnelBuilder control panel and click Connect.

If you have difficulties accessing the wireless network, do the following:

  • Make sure that you are in range of a wireless access point and your AirPort card is turned on. To do this, open AirPort, usually available from the Apple menu, and make sure your AirPort card is turned on, you have a signal, and next to "Choose network:", you've chosen the IU network (usually IU Wireless).

  • Reset your password. You can do this by using the Password Maintenance utility, available at: https://password.iu.edu/ If, when you change your password, "IU Active Directory" doesn't appear, you may need to request an ADS Domain account. For information about how to do this, see the Knowledge Base document At IU, how do I create an ADS Domain account?

  • Make sure your TCP/IP control panel is using the right configuration. When you install TunnelBuilder, the Wireless Configuration Assistant creates a new TCP/IP configuration called TunnelBuilder. If you have additional configurations, such as for connecting to the modem pools or campus Ethernet, make sure when you connect to the wireless network that the TunnelBuilder configuration is active. To do this, open the TCP/IP control panel, then from the File menu, choose Configurations... . From this window, click TunnelBuilder, then Make Active.

  • Make sure your operating system and AirPort software are up to date. The LAN TunnelBuilder installer was designed for Mac OS 9 or later and AirPort version 1.3.1 or later.
