Hoxx VPN, while primarily known for its browser extensions, offers OpenVPN connectivity as well. Configuring OpenVPN with UDP is often preferred for speed and lower overhead compared to TCP, especially in lossy network environments. Hoxx's implementation typically involves downloading a configuration file (.ovpn) and importing it into an OpenVPN client. The .ovpn file will contain directives specifying UDP as the transport protocol: proto udp.
A crucial aspect of using Hoxx VPN's OpenVPN UDP service is verifying the cipher and authentication algorithms. Examine the .ovpn file for lines like cipher AES-256-CBC or auth SHA256. Ensure your OpenVPN client supports these algorithms. Incompatible settings can lead to connection failures. Also, pay attention to the remote directive, which specifies the Hoxx VPN server's address and UDP port. Common UDP ports are 1194, 500, or a custom port.
Integrating Hoxx VPN's OpenVPN UDP service with SoftEther VPN can provide advanced routing and management capabilities. SoftEther can act as a VPN server, allowing you to chain VPN connections. To integrate, configure SoftEther as a client connecting to the Hoxx VPN OpenVPN UDP server.
Within SoftEther, create a new Virtual Network Adapter. Then, create a new VPN Client Connection. In the settings, select "OpenVPN" as the protocol and import the Hoxx VPN .ovpn file. SoftEther will parse the .ovpn file and automatically configure the connection parameters. You may need to manually adjust settings such as the virtual hub to use for the connection.
This setup allows you to leverage SoftEther's features, such as its dynamic DNS service, cascade connections to other VPNs, and granular access control. For example, you can configure SoftEther to route all traffic from a specific subnet through the Hoxx VPN connection.
When using Hoxx VPN OpenVPN UDP, ensure your firewall allows UDP traffic on the port specified in the .ovpn file. Outgoing UDP connections are typically permitted by default, but restrictive firewalls may require explicit rules.
To prevent DNS leaks, configure your OpenVPN client or SoftEther to use Hoxx VPN's DNS servers. The .ovpn file might include dhcp-option DNS <ip_address> directives. If not, manually configure your system or SoftEther to use the provided DNS servers. Use tools like dnsleaktest.com to verify that your DNS requests are being routed through the VPN. In SoftEther, DNS settings can be configured within the Virtual Hub's settings. Activate the "Use Virtual DHCP Server" option and specify the Hoxx VPN's DNS servers.
UDP, being connectionless, can be sensitive to network congestion. If you experience performance issues, experiment with different Hoxx VPN server locations. Some servers may offer better performance depending on your geographic location and network conditions.
If the OpenVPN connection fails, check the OpenVPN client logs for error messages. Common issues include incorrect credentials, firewall restrictions, or incompatible cipher settings. Increase the verbosity of the OpenVPN logs by adding verb 3 or higher to the .ovpn file. For SoftEther integration, examine the SoftEther server logs for more detailed error information. You can also experiment with different UDP fragment sizes using the fragment directive in the .ovpn file, although this is rarely needed.
