Frequently Asked Questions

Why does my QNAP VPN keep disconnecting?
VPN disconnections often occur due to unstable internet connections, incorrect port forwarding, or ISP blocking VPN traffic. Check your router's port forwarding settings and ensure your internet connection is stable.
What ports does QNAP QVPN use?
QNAP QVPN typically uses UDP port 1194 for OpenVPN and TCP port 443 for SSL VPN connections. These ports need to be forwarded in your router for external VPN access.
Can I use QNAP VPN without port forwarding?
No, external VPN access requires port forwarding to allow clients to connect through your router to the QNAP NAS. Local network VPN connections don't require port forwarding.
How do I reset QVPN service settings?
Uninstall QVPN Service from App Center, restart your QNAP NAS, then reinstall the service. This resets all configurations to default settings, requiring you to reconfigure your VPN server.
Why can't I connect to QNAP VPN from outside my network?
External VPN connections require proper port forwarding, a static or dynamic DNS setup, and your ISP must not block VPN traffic. Check these three components to resolve external connectivity issues.
