VPN Session Time

To maximize the usage of the hardware and network resource to support DKU community for their remote teaching/learning and other activities, we’ve set time limits for the VPN sessions.

Each VPN session will be expired after 12 hours from the time a user signing in. The VPN connection will be disconnected after 12 hours even if it is active. Users have to re-authenticate (login with their NetID and password) if they want to continue using it.

The VPN session will also be disconnected if the connection is idle (no traffic) for 20 minutes.

There are time limits for DKU VPN sessions. There’s a limit of up to 12 hours of each session. This means after 12 hours the VPN connection will be disconnected and if the user wants to continue using it, the user has to re-authenticate (login) with NetID and password.

Also, if the VPN connection has been idle (no traffic) for 20 minutes, it will be automatically disconnected.

Please use the above table to decide when you should be using a VPN client, which VPN client should be used, and when you should not.  Depending on your location around the world, you may or may not need to use VPN.  If you try to access a resource that currently indicates “No VPN” and are not able, please try using Duke VPN – INTL as a first step unless in mainland China then use DKU VPN.  Please also be aware that other factors (for example, your local network provider) may alter your experience and as such this table is meant to be a guide, however there may be some exceptions to when these should be used.
Please keep in mind that when using VPN, your network performance may be slower than not using VPN because all network traffic will route to Duke/DKU VPN servers.
