HelpDesk - VPN Set Up Documentation

Back to Computers at Home

Overview:

Cary Academy VPN (Virtual Private Network) Implementation is designed to help faculty and staff members connect and browse the CA network from home. It requires the installation of VPN Client software on your home computer. We have customized the installation process to make it as simple as possible.

You will need a VPN Client CD-ROM to install the software on your home computer.

You can obtain these disks from Information Services or you can send an e-mail to helpdesk@caryacademy.org.  You will have to tell us what Operating system you run on your computer. Currently VPN Client software supports Windows 95/98, Windows ME, Windows NT 4.0, Windows 2000 and Windows XP. There is also support for Macintosh and Linux operating systems. 

VPN Client Installation:

The first few steps are the same for everyone. Download the self-extracting zip file for Cisco VPN here.  Extract to a known location.  A folder on your desktop is a good choice (click Browse, scroll up to 'Desktop', highlight it, select 'OK', then at the end of the file path, add a folder name such as 'vpn' to the end.  Otherwise, the extractor will extract all files right onto the desktop.  Not pretty!)

Here is what mine looks like.  Next, click "Unzip," and a new folder named "vpn" will be created on your desktop.  Open this folder and select Setup.exe.  The setup program will then run and guide you through installation.

 

The installation program is designed to run without user interaction. At the end of the installation you will be asked to restart your PC. After you have installed the client and rebooted your PC you will have new a Program Group called “Cary Academy VPN Client”. Under that group you will find few icons including “Cary Academy VPN Access”. You are going to use this shortcut to establish a secure connection with Cary Academy network.

Special Notes:

  • IMPORTANT!!!! These instructions were written for an older version of Cisco VPN.  The newer version may look slightly different, but all the old instructions should still apply.

  • Users who have Windows 95/98/ME will have to modify their Network Properties to allow this computer to be trusted by the Cary Academy network. To do this, right click on network neighborhood icon on your desktop and choose "Properties" from the menu. In the list of installed services, double click on Client for Microsoft Network. Make sure that “Cary_Academy” is listed as a Windows NT Domain and also make sure that “Log on to Windows NT domain” check box is not checked (see figure #1). After you confirm those settings apply configuration and close all windows by pressing the OK button. You will have to reboot your system. If you don’t have Client for Microsoft Network listed consult your Windows 9x manual about how to install it.

Using VPN Client

Click on “Cary Academy VPN Access” to start the program. You will see a dialog like that shown in Figure #2.  Remember, if you have a newer version, this screen may look different, but it should be similar.

For Windows 95/98/ME users

After you hit Connect you will be asked for the username and password twice. The first authentication authorizes you to use a secure VPN connection (figure #3), the second authentication will establish your credentials on the Cary Academy network (figure #4). For both dialogs, you should type the same username and password that you use when you are at Cary Academy. After the connection is established you have access to the all resources on the Cary Academy Network that you are authorized to use. (see how to connect to your network drives)

Figure 3 Figure 4

For Windows NT, Windows 2000, and Windows XP Users

After you hit "Connect" you will be asked for the username and password. (See figure #3). You should type the same username and password that you use when you at Cary Academy. The system will negotiate security protocols and establish a secure tunnel. Now you have network connectivity to the Cary Academy LAN and can connect to the shared resources. (see how) Each time you open a connection to a new shared resource (for example connect to the data on your U: drive) you will be asked to provide username and password. You should type your username in the following format: Cary_academy\User_Name. (See figure #5).

  •  Special Notes: If you use Windows 2000 and experience problems with authentication or connection to the network shares you must check the local security policy applied to your computer. Windows 2000 must be set with a compatible security template in order to communicate with Windows NT 4.0 domain. If this is an issue you should consult the Windows 2000 manual in order to set up proper security restrictions.

Security considerations

When you use VPN connection your computer becomes a part of the Cary Academy network and all security policies that are in use in Cary Academy apply on your computer. If a hacker takes over your computer then he can easily break into Cary Academy network. This is especially dangerous for the people who have Cable modem or ADSL connection. Their computers are always online and can become easy targets for external attacks. We recommend the installation of some sort of the firewall for all people who have fast internet connections.

Computer viruses are another source of security risk. If your computer is infected then you can spread the infection to the Cary Academy network. You must always keep your anti-virus software running and always update it with the latest anti-virus signatures. You must also implement some sort of firewall technology, it can be either a hardware or software implementation. Please contact IS department if you are not sure and we will provide you with the best solution.

FAQ:

How does VPN work?

VPN (stands for Virtual Private Network) is a relatively new technology. It helps people to extend their company network to virtually anywhere. Usually a VPN implementation includes a special VPN server at the company's central location and software that has to be installed on the remote computer. People connect to the company network using a public internet connection.  VPN software encrypts data and establishes a secure "tunnel" between a remote computer and the VPN server over the public Internet.

How do I access my network data?

To access your network data you will need to follow few simple rules.

To access your U: drive if you are a faculty member. Click on Start -> Run and type \\ca\net\faculty\people\user_name. Where user_name is your actual username.

To access your U: drive if you are a staff member. Click on Start -> Run and type \\ca\net\admin\people\user_name. Where user_name is your actual username.

To access your P: drive. Click on Start -> Run and type \\ca\net\public.

To access your T: drive click on Start -> Run and type \\ca\net\faculty\common

To access your R: drive click on Start -> Run and type \\ca\net\admin\common

To access your I: drive click on Start -> Run and type \\ca\net\web

  •  Special Notes: If you use Windows NT/2000/XP and experience problem with connection to the network shares as described above you may need to replace the \\ca\net\faculty\ part with \\faculty2\  and similarly for other resources -- contact the Information Services Department for more details if you need this.

I use LinkSys or another hardware firewall. Will it work with VPN?

People who have Cable and DSL connection often use small hardware firewall. LinkSys is one of the popular firewalls on the market. CISCO VPN Client will work with such a device in most of the cases. All modern firewalls support secure VPN connection. You may experience problems if you use older device or device that doesn't comply with industry standards

I use Personal Software firewall. Will it work with VPN?

Many vendors produce personal firewalls. Some of the most popular ones are BlackIce, ZoneAlarm, Norton, McAfee. Only BlackIce and ZoneAlarm personal firewalls are certified with CISCO at this time. But most of the firewalls will work if properly configured. We were not able to run VPN client only with McAfee firewall. You may also experience problems with some other vendors that were not mentioned above. Windows XP also come with an integrated firewall - Internet Connection Firewall. VPN software is not compatible with Microsoft Internet Connection Firewall and you will need to use 3rd party vendor.  The latest version of VPN software that is currently distributed by the IS department also contains an integrated firewall.

What benefits VPN will bring me?

You may say that you already have had the  ability to dial-in to the Cary Academy network and you don't understand why use VPN.  VPN has the two following major benefits.  It allows you to connect to the Cary Academy Network from whenever you are.  Whether you are in California or you are China or France, all you need is a local Internet connection and the VPN client software on your computer.  Another benefit is for users who have fast internet connections like Cable Modem or ADSL.  These users will experience fast and reliable access to Cary Academy network from home. Also, VPN supports 50 simultaneous connections which is 6 times more than our Remote Access Service supports.  We can handle all incoming requests and you will never experience busy lines. With the campus upgrade to Windows XP we can now also provide you with Remote Desktop Connection and you can enjoy working from home as if you were at work.

Can I run applications installed on my Cary Academy computer?

You can't run applications installed on your Cary Academy computer without some additional software (Remote Desktop client) and setup (see below). You will be able to open documents that stored on Cary Academy Network but only if you have corresponding application installed on your home PC. For example, if you want to open Adobe Photoshop document you will have to have Adobe Photoshop to be present on your computer at home. However, if you have Remote Desktop client installed you may open remote session to your work computer and run all applications that you have installed on computer in your class room.

Can I use Grade Book and do grades from home?

Yes, you can now do grades from home using the VPN connection.  Please see the section on InteGrade Pro Web Access or the section that describes Remote Desktop Connection.

Why do some Cary Academy Web resources require me to authenticate?

Do not be surprised if you are asked to provide your username and password while browsing Cary Academy resources during your VPN session. Some of the resources do require additional authentication.

I am using VPN Client with Windows 95 and can not connect to any of the network shares?

Windows 95 does not understand the Distributed File System (DFS) that we use in Cary Academy. You will need to install DFS Client for Windows 95. You can find it on the same CD with VPN client under the Windows95_DFS_Client directory.  After you install it and restart your PC you will be able to access all network resources.

I am using VPN Client with Windows NT and can not connect to any of the network shares?

If you use Windows NT and experience problem connection to the network share try to connect to the network shares directly instead of using DFS paths. For example try to use \\faculty2\people instead of \\ca\net\faculty\people.

How do I get help setting up and operating VPN?

Ok. You have read this page but still confused and don't know what to do. In this case you can contact Cary Academy helpdesk by e-mail: helpdesk@caryacademy.org or you may walk-in and ask for Dmitry Manakhov (Dmitry@caryacademy.org) and you will be provided with all the help you need.

I have Apple Mac at home. Can I use it with VPN?

Yes, You can. Although it is not officially supported by Cary Academy IS department we have a word document  which will help you to set up your VPN connection from MAC computer. If you are using Macintosh computer you can open this SIT "stuffed" folder.

I use AOL as my Internet provider. I can't get my VPN to work?

Not surprising!!! We do not recommend choosing AOL as your ISP if you want to use VPN. AOL Software uses proprietary technologies and many internet and network applications do not work with AOL.  Also, unless you use broadband AOL your connection speed will be painfully slow and you won't be able to be productive anyway.
