🔐 OpenVPN Server Setup on AlmaLinux: Your Own Private Internet

Working from a coffee shop on public WiFi? 😱 That’s how I almost got hacked! Some guy was sniffing passwords until I noticed my banking app acting weird. That day I built my own VPN server and never looked back. Now I browse securely from anywhere - airports, hotels, even sketchy internet cafes! Today I’m showing you how to create your own OpenVPN server on AlmaLinux. Your internet, your rules! 🛡️

🤔 Why Run Your Own VPN Server?

Commercial VPNs promise privacy but can you really trust them? Here’s why DIY wins:

🔒 True Privacy - No logs, no selling data
🌍 Access Home Network - Reach your devices from anywhere
💰 Save Money - No monthly fees forever
⚡ Better Speed - No shared servers with thousands
🎯 Bypass Restrictions - Access geo-blocked content
🛡️ Complete Control - Your server, your rules

True story: ExpressVPN costs $100/year. My OpenVPN server on a $5 VPS handles 20 users with better speed! 🚀

🎯 What You Need

Before we tunnel to freedom, ensure you have:

✅ AlmaLinux server with public IP
✅ Root or sudo access
✅ Open ports 1194 (UDP) or 443 (TCP)
✅ Basic networking knowledge
✅ 45 minutes to secure your internet
✅ Coffee (VPN setup needs focus! ☕)

📝 Step 1: Install OpenVPN and Easy-RSA

Let’s get the VPN foundation ready!

Install Required Packages

# Enable EPEL repository
sudo dnf install -y epel-release

# Install OpenVPN and Easy-RSA
sudo dnf install -y openvpn easy-rsa

# Install additional tools
sudo dnf install -y iptables-services net-tools

# Check OpenVPN version
openvpn --version

# Enable IP forwarding
echo 'net.ipv4.ip_forward = 1' | sudo tee -a /etc/sysctl.conf
echo 'net.ipv6.conf.all.forwarding = 1' | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

# Check forwarding is enabled
cat /proc/sys/net/ipv4/ip_forward  # Should show 1

Set Up Certificate Authority

# Create Easy-RSA directory
sudo mkdir -p /etc/openvpn/easy-rsa
cd /etc/openvpn/easy-rsa

# Copy Easy-RSA files
sudo cp -r /usr/share/easy-rsa/3/* ./

# Initialize PKI
sudo ./easyrsa init-pki

# Create vars file
sudo tee vars << EOF
set_var EASYRSA_REQ_COUNTRY    "US"
set_var EASYRSA_REQ_PROVINCE   "California"
set_var EASYRSA_REQ_CITY       "San Francisco"
set_var EASYRSA_REQ_ORG        "MyVPN"
set_var EASYRSA_REQ_EMAIL      "[email protected]"
set_var EASYRSA_REQ_OU         "MyVPN CA"
set_var EASYRSA_ALGO           "ec"
set_var EASYRSA_DIGEST         "sha512"
set_var EASYRSA_CURVE          "secp384r1"
EOF

# Build Certificate Authority
sudo ./easyrsa build-ca nopass
# Enter CA Common Name: MyVPN-CA

# Generate server certificate and key
sudo ./easyrsa gen-req server nopass
sudo ./easyrsa sign-req server server

# Generate Diffie-Hellman parameters (this takes time!)
sudo ./easyrsa gen-dh

# Generate HMAC signature
sudo openvpn --genkey --secret pki/ta.key

# Copy certificates to OpenVPN directory
sudo cp pki/ca.crt /etc/openvpn/
sudo cp pki/issued/server.crt /etc/openvpn/
sudo cp pki/private/server.key /etc/openvpn/
sudo cp pki/dh.pem /etc/openvpn/
sudo cp pki/ta.key /etc/openvpn/

🔧 Step 2: Configure OpenVPN Server

Time to configure the VPN server! 🎯

Create Server Configuration

# Create server config
sudo tee /etc/openvpn/server.conf << 'EOF'
# OpenVPN Port and Protocol
port 1194
proto udp
dev tun

# Certificates and Keys
ca ca.crt
cert server.crt
key server.key
dh dh.pem
tls-auth ta.key 0
cipher AES-256-GCM
auth SHA512
tls-version-min 1.2
tls-cipher TLS-ECDHE-ECDSA-WITH-AES-256-GCM-SHA384

# Network Configuration
server 10.8.0.0 255.255.255.0
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 8.8.8.8"
push "dhcp-option DNS 8.8.4.4"
client-to-client
keepalive 10 120

# Compression (optional)
compress lz4-v2
push "compress lz4-v2"

# User and Group
user nobody
group nobody

# Persist Options
persist-key
persist-tun

# Logging
status /var/log/openvpn-status.log
log /var/log/openvpn.log
verb 3

# Connection Limits
max-clients 100

# Client Configuration Directory
client-config-dir /etc/openvpn/ccd

# Security Enhancements
remote-cert-tls client
crl-verify /etc/openvpn/crl.pem
EOF

# Create client config directory
sudo mkdir -p /etc/openvpn/ccd

# Create CRL file (Certificate Revocation List)
cd /etc/openvpn/easy-rsa
sudo ./easyrsa gen-crl
sudo cp pki/crl.pem /etc/openvpn/

Configure Firewall and NAT

# Configure firewall
sudo firewall-cmd --permanent --add-service=openvpn
sudo firewall-cmd --permanent --add-masquerade
sudo firewall-cmd --permanent --direct --add-rule ipv4 nat POSTROUTING 0 -s 10.8.0.0/24 -o eth0 -j MASQUERADE
sudo firewall-cmd --reload

# Or using iptables
sudo iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE
sudo iptables -A FORWARD -i tun0 -o eth0 -j ACCEPT
sudo iptables -A FORWARD -i eth0 -o tun0 -m state --state RELATED,ESTABLISHED -j ACCEPT

# Save iptables rules
sudo service iptables save

# Start and enable OpenVPN
sudo systemctl enable --now openvpn@server
sudo systemctl status openvpn@server

# Check if tun0 interface is up
ip addr show tun0

🌟 Step 3: Create Client Certificates and Profiles

Let’s create VPN profiles for users! 👥

Generate Client Certificate

#!/bin/bash
# Script to create client certificates

create_client() {
    CLIENT_NAME=$1
    
    echo "🔐 Creating certificate for $CLIENT_NAME..."
    
    cd /etc/openvpn/easy-rsa
    
    # Generate client certificate
    sudo ./easyrsa gen-req $CLIENT_NAME nopass
    sudo ./easyrsa sign-req client $CLIENT_NAME
    
    # Create client directory
    sudo mkdir -p /etc/openvpn/clients/$CLIENT_NAME
    
    # Copy certificates
    sudo cp pki/ca.crt /etc/openvpn/clients/$CLIENT_NAME/
    sudo cp pki/issued/$CLIENT_NAME.crt /etc/openvpn/clients/$CLIENT_NAME/
    sudo cp pki/private/$CLIENT_NAME.key /etc/openvpn/clients/$CLIENT_NAME/
    sudo cp /etc/openvpn/ta.key /etc/openvpn/clients/$CLIENT_NAME/
    
    echo "✅ Certificate created for $CLIENT_NAME"
}

# Create client
create_client "john"

Generate Client Configuration File

#!/bin/bash
# Create .ovpn profile for easy import

generate_ovpn_profile() {
    CLIENT_NAME=$1
    SERVER_IP="YOUR_SERVER_IP"  # Replace with your server's public IP
    
    cat > /etc/openvpn/clients/$CLIENT_NAME/$CLIENT_NAME.ovpn << EOF

✅ Step 4: Advanced Configurations

Let’s add power features! 💪

Split Tunneling Configuration

# Configure split tunneling (only specific traffic through VPN)
sudo tee /etc/openvpn/server-split.conf << 'EOF'
# Instead of redirect-gateway, push specific routes
# push "redirect-gateway def1 bypass-dhcp"  # Comment this out

# Route only specific subnets through VPN
push "route 192.168.1.0 255.255.255.0"
push "route 10.0.0.0 255.255.0.0"

# Or route specific domains (requires client-side configuration)
push "dhcp-option DOMAIN mycompany.local"
EOF

Per-Client Configuration

# Create static IP for specific client
echo "ifconfig-push 10.8.0.100 255.255.255.0" | sudo tee /etc/openvpn/ccd/john

# Give specific client access to internal network
cat > /etc/openvpn/ccd/admin << EOF
ifconfig-push 10.8.0.10 255.255.255.0
push "route 192.168.100.0 255.255.255.0"
push "route 172.16.0.0 255.255.0.0"
EOF

# Bandwidth limiting per client
echo "shaper 1000000" | sudo tee -a /etc/openvpn/ccd/limited-user  # 1 Mbps

Two-Factor Authentication

# Install Google Authenticator
sudo dnf install -y google-authenticator qrencode

# Configure PAM
sudo tee /etc/pam.d/openvpn << 'EOF'
auth required pam_google_authenticator.so
account required pam_unix.so
EOF

# Add to OpenVPN config
echo "plugin /usr/lib64/openvpn/plugins/openvpn-plugin-auth-pam.so openvpn" | \

# In server.conf add:
push "dhcp-option DNS 1.1.1.1"
push "dhcp-option DNS 1.0.0.1"

Problem 3: Slow VPN Speed ❌

Connection is sluggish?

# Optimize MTU
# In server.conf:
tun-mtu 1500
fragment 1300
mssfix 1300

# Change cipher
cipher AES-128-GCM  # Faster than AES-256

# Disable compression
# Comment out:
# compress lz4-v2

# Use UDP instead of TCP
proto udp

Problem 4: Can’t Access Local Network ❌

Can’t reach LAN devices?

# Add route to client
push "route 192.168.1.0 255.255.255.0"

# Enable client-to-client
client-to-client

# Add iroute for client
echo "iroute 192.168.2.0 255.255.255.0" > /etc/openvpn/ccd/client1

Monitor Logs 📊 - They reveal issues
Test Thoroughly 🧪 - From different networks
Backup Keys 💾 - Store certificates safely
Document Setup 📝 - You’ll forget details

Pro tip: Use port 443/TCP if your network blocks VPN ports. It looks like HTTPS traffic! 🥷
