Using IU's SSL VPN service for off-campus connections

Indiana University's SSL VPN service offers web-based, cross-platform access to IU's virtual private network (VPN), which provides authentication and encryption when you use an off-campus network. When you use the IU VPN, you can access IP-restricted university resources and connect to network file servers. The VPN allows you to access library databases restricted to IU students, faculty, and staff, and also to access some of the software available on IUware. The VPN may also allow you access to resources provided by your department from off campus; if you have questions, check with your IT Pro.

Note: After 30 minutes of inactivity, you will be timed out automatically. Active connections will be timed out automatically after nine hours.

Connecting to the SSL VPN

Note: To connect to IU's SSL VPN from a Linux workstation, download the installer from IUware.

To configure your SSL VPN connection from off campus:

  1. In a browser, go to

    Note: If you are a first-time user or the VPN has recently been upgraded, you will be prompted to install or upgrade the Network Connect VPN client.

  2. Enter your IU Network ID credentials.

  3. The first time you log in at that URL, the server will launch a Java application to download and install Network Connect on your computer. If you are prompted to accept a certificate from Juniper, do so by selecting Always.

  4. The browser window will remain open after you are connected; you may close it if you wish. You don't need to click Start next to "Network Connect" in the browser window. You should be able to see a Network Connect window with information about your VPN connection.

  5. To log out, click Sign Out in the Network Connect window (or in the browser window, if you have left it open).

Problems installing from your browser

If you have problems installing the client from your browser, you can obtain the installers directly from IUware:

  1. Go to IUware, and log in with your IU Network ID if prompted.

  2. Click Start Downloading on the start screen. Then click Network & Printing, select Juniper SSL VPN, and follow the instructions to download and install the file.

  3. To run the application, log into with your IU Network ID.

    Note: Windows and Mac users may also run the application directly using the local installer.

    1. Windows: To install, click Program Files > Juniper Networks > Network Connect 7.3.1. You must be logged in with administrator privileges to complete the installation.

    2. Mac: Click Applications > Network Connect to install. While trying to launch the Network Connect installation package, you may receive a message saying, "Network Connect.pkg can't be opened because it is from an unidentified developer".

      If this happens, you can attempt to re-launch the application. Right-click (or Ctrl-click) the Network Connect.pkg icon, and choose Open. A dialog box will appear with a similar warning, but you will have the option to continue opening the installer.

Problems running Network Connect

A recent Java update may cause you to experience problems opening the Network Connect application after you log into In Windows, you maybe be repeatedly prompted to download or run the Juniper Setup Client. In OS X, you may see the error "Security Exception: Missing required Permissions manifest attribute in main jar".

To handle this issue, add an exception for from the Java Control Panel:

  1. In Windows, from the Start menu, click Control Panel, and then select Java (32-bit). (If Java is not listed, click View by: at the upper right and change to Large icons or Small icons.)

    In OS X, from the Apple icon at the top left, select System Preferences, and then click the Java icon.

  2. In the Java Control Panel, select the Security tab, and then click Edit site list.

  3. Click Add and enter

  4. Click OK.

Note: You need to upgrade your Network Connect client only when UITS upgrades the software on the VPN server itself. Your Network Connect client version and the SSL VPN server software version must match.

When UITS upgrades the SSL VPN server software, you will be prompted to upgrade your Network Connect client software at your next login. You can do so automatically in one of two ways, while logged into your computer as an administrator:

  • After you have connected to and entered your username and password, you will be prompted to upgrade. Once you do so, installation will occur automatically; you may be prompted for permission(s) during the process. After the installation is complete, the Network Connect client will launch and connect.

  • If you launch the Network Connect client manually, you will be asked to upgrade the software after you log in. The software will then automatically download and install, and the VPN session will connect.

Alternatively, to upgrade your software using a local installer, download the Network Connect client installer for Windows, Mac, or Linux from IUware. UITS will make upgraded software available on the day of the SSL VPN upgrade, in IUware's Network & Printing section for your operating system.


  • Windows: To install the client on a Windows computer, you must be logged in with administrator privileges.

  • Mac: When you attempt to launch the Network Connect installation package, you may see a message such as, "Network Connect.pkg can't be opened because it is from an unidentified developer".

    Re-launch the application by right-clicking (or Ctrl-clicking) the Network Connect.pkg icon and choosing Open. A dialog box displaying a similar warning will appear, but you will have the option to continue opening the installer.
