+## Suricata IPS Integration for Proxmox
+
+This document provides a detailed guide for integrating Suricata as an Intrusion Prevention System (IPS) within your Proxmox VE environment.
+
+### Note
+- Packets will be forwarded to the IPS only after the firewall ACCEPTed them.
+- Rejected/Dropped firewall packets don’t go to the IPS.
+
+This try follow [PVE Firewall#_suricata_ips_integration](https://pve.proxmox.com/wiki/Firewall#_suricata_ips_integration)
+
+**1. Installation and Configuration:**
+
+```bash
+# Install Suricata and necessary tools
+apt-get -y install suricata jq
+
+# Load nfnetlink_queue module
+modprobe nfnetlink_queue
+echo "nfnetlink_queue" > /etc/modules-load.d/nfnetlink_queue.conf
+
+# Configure Suricata for NFQUEUE
+sed -i 's/NFQUEUE=.*/NFQUEUE=0-3/' /etc/default/suricata
+```
+
+**2. Suricata Configuration:**
+
+```bash
+# Adjust interface (replace 'vmbr0' with your public interface)
+sed -i 's/interface: eth0/interface: vmbr0/g' /etc/suricata/suricata.yaml
+
+# Enable community-id and rule-reload
+sed -i 's/community-id: false/community-id: true/' /etc/suricata/suricata.yaml
+echo "detect-engine:" >> /etc/suricata/suricata.yaml
+echo "  - rule-reload: true" >> /etc/suricata/suricata.yaml
+```
+
+**3. Rule Updates:**
+
+```bash
+# Update Suricata rules
+suricata-update update-sources
+suricata-update enable-source et/open
+suricata-update -o /etc/suricata/rules
+
+# Schedule automatic rule updates (every day at 02:00)
+crontab -e
+0 2 * * * suricata-update -o /etc/suricata/rules
+```
+
+**4. Testing Suricata:**
+
+```bash
+# Test Suricata configuration
+suricata -T -c /etc/suricata/suricata.yaml -v
+```
+
+**5. Setting Suricata as IPS:**
+
+```bash
+# Edit Suricata service to run as IPS
+systemctl edit suricata.service
+
+[Service]
+ExecStart=
+ExecStart=/usr/bin/suricata -c /etc/suricata/suricata.yaml --pidfile /run/suricata.pid -q 0 -vvv
+Type=simple
+
+# Reload and restart Suricata service
+systemctl daemon-reload
+systemctl restart suricata
+```
+
+**6. Configuring VM/CT Firewall for IPS:**
+
+```bash
+# Edit VM/CT firewall configuration (replace '<VMID>' with your VM/CT ID)
+nano /etc/pve/firewall/<VMID>.fw
+
+[OPTIONS]
+enable: 1
+ips_queues: 0:3
+ips: 1
+```
+
+**7. Monitoring Suricata Alerts and Statistics:**
+
+```bash
+# View Suricata alerts
+tail -f /var/log/suricata/eve.json | jq 'select(.event_type=="alert")'
+
+# View Suricata IPS statistics
+tail -f /var/log/suricata/stats.log | grep ips
+```
