If you are having a problem about VPN service, please read the Troubleshooting and Frequently Asked Questions pages.

What is VPN (Virtual Private Network)?
Internet security usually requires services/resources to be restricted to computers located in a campus network, a corporate network, even much smaller departmental networks. On the other hand, users frequently need to access these restricted resources from foreign networks, such as from their homes, hotels, airports, etc.

VPN is a tool to connect a computer which is sitting outside the campus network, and renders it to become part of the campus/corporate network through the public Internet. Simply put, the client computer becomes part of the network with which it establishes a VPN connection; regardless of where actually it is connected to the Internet.

Bilkent VPN services
VPN services at Bilkent were established and maintained for those Bilkenters who need to access some resources restricted to Bilkent University network’s IP address blocks. Some examples are Library resources, STARS services during registrations, EBYS (Electronic Document Management System.

Recently we have been observing VPN connectivity issues depending on the hardware and software platforms used, and even on the client’s location and on the policies of the client’s Internet service provider.

During the course of time the PPTP VPN protocol has been abandoned by Apple, Microsoft has introduced SSTP VPN, which is a secure and easy to install-easy to use protocol.

Bilkent’s new VPN server, namely vpn-ng.bilkent.edu.tr is a multi-protocol server. It supports various VPN protocols that our users can choose from.

Different platforms have different tools/methods for establishing a VPN connection. Our protocol recommendations, based on ease of use and whether a protocol is natively supported by the operating system can be found here:
