Advanced Configuration
Protocol Selection: TCP vs UDP
UDP (Recommended)

- โ Bypasses some firewalls
- โ Slightly slower
Coronium provides both options. Start with UDP and switch to TCP only if you experience connection issues.
Kill Switch Configuration
A kill switch blocks all internet traffic if your VPN connection drops, preventing IP leaks.
Enable Kill Switch:
- Windows: OpenVPN GUI โ Settings โ Advanced โ "Block IPv4/IPv6"
- macOS: Tunnelblick โ VPN Details โ "Kill Switch" option
- Mobile: OpenVPN Connect โ Profile Settings โ "Seamless Tunnel"
DNS Leak Prevention
Ensure all DNS queries route through the VPN tunnel to prevent leaks.
# Add to your .ovpn file: block-outside-dns dhcp-option DNS 8.8.8.8 dhcp-option DNS 8.8.4.4
Split Tunneling
Route only specific applications or websites through the VPN while others use your regular connection.

Frequently Asked Questions
How long does it take to set up OpenVPN with Coronium?
The entire setup process typically takes less than 5 minutes. This includes downloading the configuration file, installing the OpenVPN client, and establishing your first connection.
Which OpenVPN clients work with Coronium?
Coronium's configuration files work with all standard OpenVPN clients including OpenVPN Connect, Tunnelblick (Mac), OpenVPN GUI (Windows), and the official OpenVPN apps for iOS and Android.
Can I use the same configuration on multiple devices?
Yes, you can use your Coronium OpenVPN configuration on multiple devices, but simultaneous connections may be limited based on your subscription plan. Check your plan details for concurrent connection limits.
What's the difference between TCP and UDP protocols?
UDP is faster and recommended for most users, offering better performance for streaming and general browsing. TCP is more reliable and can work better in restrictive network environments or when UDP is blocked.
How do I troubleshoot connection issues?
Common solutions include: checking your internet connection, verifying credentials, trying a different protocol (TCP vs UDP), temporarily disabling firewall/antivirus, or downloading a fresh configuration file from your dashboard.
Is my traffic truly anonymous with OpenVPN?
OpenVPN provides strong encryption and masks your real IP with a Coronium residential IP. However, complete anonymity depends on your browsing habits, enabled cookies, and other factors beyond the VPN connection.
What makes Coronium's VPN different from others?
Coronium uses genuine mobile carrier IPs (4G/5G) instead of datacenter IPs, providing better compatibility with services that block traditional VPNs. Our IPs appear as regular mobile user traffic.
Can I change my VPN location after setup?
To change locations, you'll need to download a new configuration file for your desired country from your Coronium dashboard. Each location requires its own .ovpn file.
