Do I need a VPN when I am on campus?
Atualizado/Updated: 2026-05-12
Target Audience: Iscte Community
Answer/Solution:
No. When you are connected to ISCTE networks (via cable or institutional Wi‑Fi), you are already within the internal network, so a VPN is not necessary. The VPN should only be used when you are off campus.
Exceptionally, access to some applications or services may require connecting to the VPN, even on campus.

Answer/Solution:
Iscte’s VPN allows access, outside the campus, to resources that are only available within the institutional network, such as:
- Internal academic and administrative systems
- Network servers and folders
- Applications and software with licensing restricted to Iscte
- Scientific databases that require authentication via institutional IP
Without the VPN, these services may not be accessible when the user is at home or on another external network.

Answer/Solution: If you have MFA configured and you get the error ‘Connection Failed’ as shown in the image below:

You should do the following:
- For Windows computers, you’ll need to make sure you’ve installed the correct version of the 32/64-bit VPN.
- Check that you don’t have the IP and DNS configured manually (e.g. 8.8.8.8 or 8.8.4.4).
- If you have antivirus software, we recommend disabling pop-up blocking in your browser. Or choose another browser as your default.
- Alternatively, uninstall the VPN (GlobalProtect):
– Windows – Through the Control Panel > Select Programs > Programs and Features and, after uninstalling, restart the computer. Then install and configure the VPN again.
– MacOS – Run globalprotect Setup > continue/next> select ‘Uninstall GlobalProtect.’ After uninstalling, restart the computer. Then install and configure globalprotect (VPN) again.
