Troubleshot VPN Access
If you encounter any issues while using the VPN Access feature, please refer to the following list of common problems and their respective solutions:
Handshake Failure (VPN Connection Inactive)
- Firewall Settings: Ensure that the firewall on your device allows traffic through the WireGuard UDP port.
- Server Ping Test: Verify that your server can successfully ping the WireGuard Server IP address
default: 10.250.0.1 - Configuration File: Double-check that the imported WireGuard configuration file is correct and not corrupted.
Loss of Internet Connectivity After Enabling VPN
This issue typically occurs due to a DNS configuration conflict.
- Option A: Open your WireGuard configuration file, locate the DNS line, and comment it out by adding a hash symbol (#).
Example: #DNS = 8.8.8.8, 8.8.4.4 - Option B: Alternatively, change the DNS settings to a value permitted by your organization's policy.
Destination Unreachable (Request Timeout / RTO)
- ICMP Test: Perform a PING test from your local machine or the server configured as the WireGuard Client to the target IP address.
- Target Firewall: Ensure that the firewall rules on the target system allow incoming traffic from the WireGuard subnet.
- OS Guide Verification: Ensure you have strictly followed the instructions in the WireGuard Installation and User Guide for your specific operating system.
- Windows: Reconfigure the settings according to step 6 of the WireGuard Installation and User Guide for Windows OS.
IP Forwarding Configuration Issues (OS-Specific)
Linux: Ensure that IPv4 Forwarding is enabled by executing the following command:
sudo sysctl -w net.ipv4.ip_forward=1macOS: Ensure that Sysctl IPv4 Forwarding is active by running:
sudo sysctl -w net.inet.ip.forwarding=1Additionally, verify that the PF (Packet Filter) configuration has been properly reloaded.
Dual-VPN Configuration Conflicts
- Routing Conflict: If you are connected to an internal corporate VPN simultaneously with Helium VPN, ensure that the routing paths of both connections do not conflict.
- Traffic Allowance: Ensure that the internal VPN permits outbound traffic to the Helium Cloud infrastructure for scanning purposes.
Firewall & Antivirus Blocks
- Endpoint Protection: Check whether the antivirus or endpoint protection software on your device is blocking the WireGuard VPN connection.
- Deep Scanning Exclusions: For operations requiring deep network scanning (such as Port Scanning or Service Enumeration), consider temporarily disabling or adjusting the rules of the antivirus/firewall on the target system.
