What does split and full tunnel mean? What is the difference?


OSU has two types of VPN? connections available.

Split Tunnel - Routes and encrypts all OSU bound requests over the VPN.

Examples include: Blackboard?, Outlook web mail, OSU web pages, etc. All other internet traffic is NOT encrypted or sent over the VPN. Examples include: Amazon, Facebook, Google, Yahoo, etc.

Full Tunnel - Routes and encrypts ALL requests through the VPN to OSU. Examples include: OSU Blackboard, Outlook webmail, Yahoo, google, etc. Once that request leaves OSU for another destination, such as Yahoo, it is NOT encrypted over the VPN tunnel.

  • Note: WebVPN is Full Tunnel only.
