<h3 style="color: #ffffff; margin-top: 20px;">Firewall Configuration</h3>
<p style="color: #e5e7eb;">Allow server ports through your firewall:</p>
<pre><code style="color: #a5b4fc;"># UFW (Ubuntu/Debian)
sudo ufw allow [PORT]/tcp
sudo ufw allow [PORT]/udp
sudo ufw reload
# FirewallD (CentOS/RHEL)
sudo firewall-cmd --permanent --add-port=[PORT]/tcp
sudo firewall-cmd --permanent --add-port=[PORT]/udp
sudo firewall-cmd --reload
# Windows Firewall
netsh advfirewall firewall add rule name="Left 4 Dead Server" dir=in action=allow protocol=TCP localport=[PORT]
netsh advfirewall firewall add rule name="Left 4 Dead Server" dir=in action=allow protocol=UDP localport=[PORT]

<h3 style="color: #ffffff; margin-top: 20px;">⚠️ Port Security Notes</h3>
<ul style="color: #fef3c7; line-height: 1.8;">
<li>Only open ports that are necessary for the game server to function</li>
<li>Consider using non-standard ports to reduce automated attacks</li>
<li>If using cloud hosting, configure security groups properly</li>
<li>Monitor connection attempts and unusual traffic patterns</li>
</ul>
