Off-Campus Computing for Windows 2000

Win 2000: Off-Campus Computing

Platform: Windows

General Information

If you live off campus, you have a choice of how you will access UB and the Internet. You can pay for a third-party Internet Service Provider (ISP), such as Time Warner Road Runner or Verizon, and connect to UB through a secure tunnel, or you can use a modem and dial up to UB's modem pool.

 

Note

The UBVPN client does not work with AOL. To access UB services from AOL, see the section Connecting from AOL.

UB provides a VPN client to allow for a secure tunnel to UB from third-party Internet Service Providers (ISPs) such as Adelphia or Verizon.

There are nearly 1,000 UB modems that students can use to dial in to UB directly. There are separate modem dial-up numbers for Erie County (UB is located in Erie County), most of Niagara County, and a separate number for Middleport, Gasport, Newfane, Barker, and parts of Lockport. When the correct number is used for your area, the cost is a local phone call. Be sure to check with your local telephone service provider to ensure you select the correct number for your area, and that the cost is a local phone call.

The UB Virtual Private Network (UBVPN) Client is available for installation, allowing you to securely connect to the University's computer systems from an off-campus Internet Service Provider (ISP). You can access shared files of a server or campus resources as if you were directly connected.

With a wireless network card installed in your laptop, you can be assured of a secure connection to the network in UB's wireless access zones. Setup instructions are available in the UB Wireless Network Access document.

Using UBVPN to Connect from Third-Party ISPs

The UBVPN Client is available on the Tech Tools CD, or you can download it from http://wings.buffalo.edu/computing/software/. Click on the link for Windows downloads, and select UBVPN from the list of available downloads.
