← Back to Support Documentation

📋 Before You Begin

Ensure you have your CodaMail VPN credentials ready. You’ll need your VPN username and password (different from your email login) to connect to our secure VPN servers.

Important: All VPN and proxy servers are under the cotse.net domain. The codamail.com domain is exclusively for email services.

📱 Step 1: Install OpenVPN Connect

  • Open the App Store on your iPhone or iPad.
  • Search for “OpenVPN Connect” (by OpenVPN Inc.).
  • Tap “Get” to install the official OpenVPN Connect app.
  • Open the app once installation is complete.
  • Allow location access and notifications if prompted (optional but recommended).

📥 Step 2: Download Configuration Files

Download one or more of the following OpenVPN configuration files to your iOS device:

London Server

Server: london.cotse.net

Config File: london.ovpn

Location: United Kingdom

Chicago Server

Server: chicago.cotse.net

Config File: chicago.ovpn

Location: United States (Illinois)

Amsterdam Server

Server: amsterdam.cotse.net

Config File: amsterdam.ovpn

Location: Netherlands

⚙️ Step 3: Import Configuration File

Method 1: Direct Download (Recommended)

  • Download the .ovpn file using Safari on your iOS device.
  • When the download completes, tap on the file.
  • iOS will ask “Open in OpenVPN?”. Tap “Copy to OpenVPN”.
  • OpenVPN Connect will open automatically with the profile imported.

Method 2: Manual Import

  • Open OpenVPN Connect app.
  • Tap the “+” button to add a profile.
  • Select “File” tab.
  • Choose “Browse” and locate your downloaded .ovpn file.
  • Select the file to import it.

🔐 Step 4: Configure Authentication

  • After importing, you’ll see the profile in your list.
  • Tap on the profile to configure it.
  • Enter your CodaMail VPN credentials:
    • Username: Your VPN username
    • Password: Your VPN password
  • Toggle “Save Password” on for convenience (optional).
  • Tap “Add” to save the profile.

🚀 Step 5: Connect to VPN

  • From the main screen, tap the toggle switch next to your server profile.
  • iOS will ask for permission to add VPN configurations. Tap “Allow”.
  • You may need to authenticate with Face ID, Touch ID, or passcode.
  • The status will change to “Connected” with a green indicator.
  • You’ll see a “VPN” indicator in your status bar when connected.
  • Your internet traffic is now secured through the VPN tunnel.

🌍 Choosing the Right Server

Performance Considerations

  • London: Optimal for European users, excellent global connectivity.
  • Chicago: Best for North American users, central US location.
  • Amsterdam: Great for European users, strong privacy protections.

Network Optimization

  • Default Port: Config files use port 1194/UDP by default.
  • Alternative Ports Available: If blocked, servers also listen on:
    • UDP: 20, 123, 31482 (bypasses most firewalls).
    • TCP: 443, 80, 993 (works on restrictive networks).
  • You can manually edit the .ovpn file to change remote server-address 1194 udp to use any alternative port.

Usage Tips

  • Select the server geographically closest to you for optimal speed.
  • Switch servers if you experience connectivity issues or slow performance.
  • Configure multiple server profiles for different use cases.
  • Consider server location when accessing region-specific content.
