Off-Campus Computing for Windows XP (dial-in to UB)

Introduction

If you live off campus, you can choose how you access the University at Buffalo's computer systems and the Internet. You can pay for a third-party Internet Service Provider (ISP), such as Adelphia or Verizon, and connect to UB through a secure tunnel (UBVPN), or you can use a modem and dial in to UB's modem pool.

There are UB modems that students can use to dial directly into UB. There are separate modem dial-up numbers for Erie County (UB is in Erie County), and for select areas in Niagara County, which include Middleport, Gasport, Newfane, Barker, and parts of Lockport. When you use the number appropriate to your area, the cost for each connection is usually equivalent to the cost of a local phone call. Check with your local telephone service provider to ensure that you select the correct number for your area. Rates can vary depending on your location, service provider, and telephone plan.

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).

Connecting to UB from AOL

To access UB from your AOL account, you must first connect to the Internet using AOL, and then register your IP address using your web browser by going to telnet://remote.buffalo.edu. If you only need access for a week, enter your UBITName in the Username field, then press Enter twice. If you need access for more than one week, enter your UBITName in the Username field, press Enter, enter the letter c, then press Enter. Then, insert the first two parts of the IP address displayed at the start of your session and press Enter. Enter the number of weeks for which you want access (up to 12 weeks), and press Enter.

Setting Up Your Dial-Up Modem Connection to UB
