The library's subscription resources are configured to allow seamless access to any computer on Missouri S&T's network. In order to provide optimal access to off-campus users, these resources are set up to allow access through the library's proxy server, which requires you to log in with your campus-wide user ID and password at the beginning of each session.
This situation can become complicated if you also need to access the library's resources while also using your Missouri S&T S: drive or email from off campus. Access to those resources is provided by the campus IT department, who require you to use a Virtual Private Network (VPN).
The VPN instructions provided by IT are designed to optimize the performance of your off-campus internet access. Such a VPN will allow you seamless access to all resources hosted by Missouri S&T, but it will have no effect on other resources.
Unfortunately, there is a conflict between such a VPN and the library's proxy server. If you are running a VPN set up according to IT's instructions, you will bypass the library's proxy server when trying to access a library database. Because these databases are not hosted by Missouri S&T, though, you will also be unable to access their subscription content.
The recommended solution is to turn off your VPN when trying to access library databases and subscription journals from off campus. This will remove your ability to access your email and S: drive, though, so there is a trade-off.
Another solution is to configure your VPN according to the instructions provided by the library. This has a serious downside in that it will route all of your internet traffic through a server on campus, causing your internet connection to become very slow.
