1: What is VPN?

VPN stands for Virtual Private Network. A VPN allows you to use the Internet Service Provider (ISP) of your choice to connect to NJIT's network and use services typically restricted to use on campus. This occurs through a "Virtual" network connection to NJIT, meaning that even though you are connected to your ISP, you will function as if you are directly connected to NJIT network.

8: When I use system names like MAIL or AFS11, I get "host not found" errors. Why is this happening?

While VPN is active you are still connected using your ISP's domain root (ie. home.com, att.net). This means you MUST fully qualify your NJIT system names, including the njit.edu domain name. You must use SYSTEM-NAME.njit.edu to contact systems at NJIT. For example, use afs11.njit.edu for a Highlander AFS system.

9: Can I use my NJIT UCID for the VPN?

Yes. The VPN server authenticates using your UCID and UCID password. Administrative and Academic users must have a UCID to use the VPN services. If you do not have a UCID, you may apply for a new account online. If you are having login issues related to your UCID and/or password, please consult our UCID FAQ.

13: What is the difference between the full and split VPN tunnel options?

Split Tunnel 

When using a split tunnel only your traffic to campus will be encrypted and secured between your computer and the VPN. The “split” tunnel only sends traffic destined for NJIT over the VPN connection.  All other traffic goes through your normal cable modem/dsl connection.  Use the “split” tunnel for connections to and from NJIT only.

Benefits:

  1. It conserves campus network bandwidth. When fewer packets travel to campus, more bandwidth is available. This reduces delays on the network (lag) for campus users. Additionally, your non-campus traffic is not counted against any campus bandwidth limits.
  2. It helps protect privacy. The university's privacy policy  strives to keep your information confidential, and this extends to your VPN connection. If you visit a Web page or server from home that is not located on the NJIT campus, that information never reaches the VPN server. Your home network traffic will not be limited or monitored in any way by the VPN.

More information here.

Full Tunnel 

When using a full tunnel all of your network traffic will be routed through an encrypted connection to the VPN and then from the VPN to its intended destination.  The “full” tunnel sends all your internet traffic through the VPN connection, and then out to the internet through NJIT’s connection.
