Häufig gestellte Fragen
The VPN Tracker 365 Connection Checker helps determine which VPN protocols your current internet connection supports. This is particularly useful in places like hotels, cafés, or offices, where network restrictions may apply.
Understanding the Results
- ✅ Green Check Mark: The protocol was successfully tested and is expected to work on your current network.
- ⚠️ Yellow Exclamation Mark: The test was inconclusive. The protocol may or may not work due to network restrictions or unstable conditions. You can try connecting, but success isn't guaranteed.
Why is a VPN Protocol Not Working?
If a protocol gets a ⚠️ yellow exclamation mark, possible reasons include:
- Network Restrictions – Some Wi-Fi networks (hotels, workplaces) limit or block certain VPN protocols.
- Firewall Rules – A firewall may be filtering VPN traffic, preventing stable connections.
- ISP Limitations – Some internet providers restrict or throttle VPN usage.
- Router Settings – Your router may not allow VPN passthrough for certain protocols (e.g., PPTP, L2TP).
- Double NAT Issues – If you're behind multiple routers (common in hotels, mobile networks), VPN connections can be disrupted.
- Unstable Internet Connection – High packet loss or weak connectivity can interfere with VPN protocols.
Explanations for the VPN Connection Test for IPsec
For IPsec, at least the ESP (Encapsulating Security Payload) or NAT-T (Network Address Translation Traversal) protocol must function to establish a stable VPN connection. Often, ESP is not usable in certain environments, such as due to firewall settings or network configurations. However, as long as NAT-T is available, the connection can still be established.
What to Do If a Protocol Fails?
- Switch networks – If possible, test from a different Wi-Fi Network
- Try a mobile hotspot – Create a hotspot with your mobile phone and test if you get a different result
- Try a different protocol (e.g., if IKEv2 is unstable, try OpenVPN).
- Check router settings if you're on a home or office network.
- Use VPN Tracker's built-in troubleshooting tools for more insights.
With the VPN Tracker Connection Checker, you can quickly identify network issues and choose the best protocol for a stable connection.
