Virtual Private Network (VPN) offers a secure network connection that is layered on top of a public network, such as the Internet or EDUROAM. It makes use of the Internet's infrastructure to move secured data to and from the campus network. Using VPN, off-campus students and staff can still access the University's online resources in the comfort of their home computer, through their ISP (Internet Service Providers) like SingNet, StarHub, etc. using dial-up or broadband service.
Through VPN, you'll have access to the University's e-services or computing facilities that are not made available on the Internet or WWW (World-Wide Web). These include access to your Laboratory's UNIX servers, network printers, file shares, personal web storage folders, etc.
There are 2 types of VPN service supported in NTU -- you can connect to NTU e-resources using either
SSL VPN (NTUVPN) or
Microsoft VPN (VPNGATE). If you are using Mac OS or Linux, you are encourage to use NTUVPN. For Microsoft Windows OS user, you can choose either options. You'll need only your Network Account to login to this VPN service. For a quick guide on configuring VPN on your computer, please visit the
Quick Start Guide.
VPN on NTUwireless
The convenience of wireless LAN also come with some inherent risks. To ensure full data privacy on
NTUwireless, our campus wireless network, you can also use this VPN service to "dial-out" of NTUwireless - just as you normally would using VPN on the Internet to access NTU network.
For computers connected to the campus wired network, VPN connection is however not necessary. This service is not turned on for the wired network.
VPN client behind the Corporate Firewall
Except for Singnet, Starhub or the overseas ISP, most organisations and universities have some form of firewall implementations on their Internet gateway.
Both SSL VPN (NTUVPN) or Microsoft VPN (VPNGATE) offerred client connection via SSL VPN services.
However for Microsoft VPN client on Windows that does not support SSTP (SSL VPN), the VPNGATE will negotiate to establish connection using PPTP protocol via TCP port 1723 & GRE tunnel.
Mac VPN client connection to the MIcrosoft VPN (VPNGATE) is also using PPTP protocol via TCP 1723 & GRE tunnel.
The organisation's Firewall requires
PPTP traffic via TCP port 1723 & GRE tunnel to pass through the Firewall.
Note- Computer OS on Windows 7 and above supported Microsoft SSTP VPN
