Using UBVPN for Windows Vista/XP

Introduction

The UB Virtual Private Network (UBVPN) Client allows you to securely connect to Wireless Internet Zones on campus. It also allows you to securely access UB resources while off campus when connected from third-party Internet Service Providers (ISPs) such as Time Warner's Road Runner and Verizon. It cannot be used from within ResNet, wired offices on campus, wired OpenPort connections, or dial-up to UB (UB PPP).

Firewall Issues

If you are running a firewall or a router for a home network, you must allow the following types of traffic to pass through: UDP port 500 (ISAKMP), IP protocol 50 (ESP), and UDP port 4500 (for use with NAT and NAT-T).

UBWireless

You must have a wireless network card installed in your computer to use UBWireless. Your computer must be configured to use DHCP.

If your computer does not connect after following the instructions, you should follow the steps in the section Configuring Your Network Settings, and then follow the steps for Installing UBVPN.

Using UBVPN

To use the UBVPN Client from off campus, you must first connect to the Internet using an off-campus ISP.

You can also use the UBVPN Client to connect to a Wireless Access Point on campus if you have a wireless network card installed in your machine.

1. Click start, select All Programs, Cisco Systems VPN Client, then VPN Client.
2. Select offcampus from the Connection Entry choices if you are connecting from an off-campus ISP such as Time Warner Road Runner or Verizon DSL. Select oncampus from the Connection Entry choices if you are connecting in a Wireless Internet Zone on campus.
   
3. Click Connect.
4. Enter your UBITName and Password, then click OK.
   

Note

Power management modes differ from laptop to laptop. If you are using a laptop connected to a wireless network, when your computer goes into sleep mode, the wireless network card will drop your Internet connection. Stop and restart the UBVPN Client to reconnect to UBVPN.

5. A UB banner will appear. Click Continue to connect.
   
   

UBVPN Session Timeout

The UBVPN session will time out after 30 minutes of off-campus inactivity or 24 hours of use. If UBVPN times out and your IPSec connection is terminated, click OK, then launch the UBVPN Client again.

Disconnecting from UBVPN

When you finish accessing UB's network and want to disconnect from UBVPN, right-click on the UBVPN icon (which resembles a padlock) in the System Tray of the Taskbar at the bottom of the screen, then select Disconnect.
