Quick Start

1. Prepare files:

# Add your ProtonVPN credentials to ovpn/ directory
# Each credentials file = 2 VPN connections (ProtonVPN limit)
cp ~/Downloads/*.ovpn ovpn/
echo "your_username" > ovpn/credentials.txt
echo "your_password" >> ovpn/credentials.txt

2. Run setup:

cd VPN-Setup
sudo ./setup.sh full

3. Start system:

sudo /usr/local/bin/multi-vpn-proxy.sh start

Adding New VPNs

Simply add more files to the ovpn/ directory:

# Add more .ovpn files
cp ~/Downloads/*.ovpn ovpn/

# Add more credentials (if needed)
cp your_credentials ovpn/credentials-4.txt

# Re-run setup
sudo ./setup.sh full

The system automatically:

• Discovers all .ovpn files
• Assigns credentials by pairs (every 2 VPNs = 1 credentials file)
• Creates users and routing tables

Commands

# Main system
sudo /usr/local/bin/multi-vpn-proxy.sh start    # Start all VPNs
sudo /usr/local/bin/multi-vpn-proxy.sh stop     # Stop all VPNs
sudo /usr/local/bin/multi-vpn-proxy.sh status   # Check status
sudo /usr/local/bin/multi-vpn-proxy.sh test     # Test connections

# Debugging
sudo /usr/local/bin/vpn-debug.sh status         # Debug status
sudo /usr/local/bin/vpn-debug.sh test           # Test proxies

# Security monitor
sudo /usr/local/bin/vpn-monitor-control.sh status   # Monitor status
sudo /usr/local/bin/vpn-security-monitor.sh start    # Start monitor

# Run tests
sudo /usr/local/bin/vpn-unit-test.sh

How It Works

Each VPN gets:

• Unique port (1080, 1081, 1082, etc.)
• Unique routing table (100, 101, 102, etc.)
• Unique tun device (tun0, tun1, tun2, etc.)
• Unique user (vpnuser100, vpnuser101, etc.)

Traffic is routed through policy routing:

• Each proxy user (vpnuserXXX) has its own routing table
• Traffic from each SOCKS5 proxy goes through its own VPN

Features

• ✅ Auto-discovery of VPN configurations
• ✅ Dynamic port and routing assignment
• ✅ Automatic credentials integration
• ✅ Security monitoring
• ✅ Multiple account support (2 connections per account)
• ✅ Portable across Linux distributions
• ✅ SOCKS5 proxy for each VPN

Testing

# Test all proxies
for p in 1080 1081 1082 1083 1084 1085; do
    echo -n "Puerto $p: "
    curl -s --socks5 127.0.0.1:$p https://ifconfig.me
done

Troubleshooting

If VPNs don't connect properly:

# Check routing rules
ip rule list | grep uidrange

# Check interfaces
ip addr show | grep tun

# Restart with clean state
sudo /usr/local/bin/multi-vpn-proxy.sh restart
