+# HAProxy & PFSense Bot, AI & Scraper Blokkering
+
+Deze handleiding legt uit hoe je op netwerkniveau (via HAProxy op PFSense) bots, AI-crawlers en scrapers blokkeert **voordat ze je CodePress CMS webserver bereiken**.
+
+---
+
+## 1. Randvoorwaarde: Echte Bezoeker IP's doorsturen (`X-Forwarded-For`)
+
+Om te zorgen dat CodePress CMS en HAProxy het echte IP-adres van de bezoeker zien (in plaats van het interne PFSense IP zoals `192.168.210.1`):
+
+1. Ga in PFSense naar **Services → HAProxy → Frontend** en bewerk je Frontend.
+2. Zorg dat het **Type** op **`http / https (offloading)`** staat.
+3. Vink onder **Advanced settings** aan: **`Use option forwardfor`**.
+4. Voeg onderaan bij **Advanced pass thru** toe:
+   ```text
+   http-request set-header X-Real-IP %[src]
+   ```
+5. Sla op en klik op **Apply Changes**.
+
+---
+
+## 2. HAProxy ACL Regels (User-Agent Blokkering)
+
+Voeg in HAProxy Frontend onder **Advanced pass thru** de volgende ACL-regels toe om AI-bots en scrapers direct een `403 Forbidden` te geven:
+
+```text
+# Detecteer AI Bots
+acl is_ai_bot req.fhdr(User-Agent) -i -m sub GPTBot ChatGPT-User ClaudeBot Claude-Web CCBot PerplexityBot Bytespider FacebookBot Google-Extended Applebot-Extended
+
+# Detecteer Scrapers & Automated Tools
+acl is_scraper req.fhdr(User-Agent) -i -m sub HTTrack Scrapy HeadlessChrome PhantomJS curl wget python-requests libwww-perl
+
+# Detecteer Lege User-Agents
+acl is_empty_ua req.fhdr(User-Agent) -m len 0
+
+# Blokkeer als een van de regels matcht
+http-request deny deny_status 403 if is_ai_bot
+http-request deny deny_status 403 if is_scraper
+http-request deny deny_status 403 if is_empty_ua
+```
+
+---
+
+## 3. HAProxy Rate Limiting (Stick Tables)
+
+Om overbelasting door agressieve scrapers te voorkomen op netwerkniveau, kun je een stick table toevoegen aan je HAProxy Frontend (**Advanced pass thru**):
+
+```text
+# Houd verzoeken per IP bij (1 minuut venster)
+stick-table type ip size 100k expire 1m store gpc0,http_req_rate(60s)
+tcp-request connection track-sc0 src
+
+# Blokkeer IP als er meer dan 60 verzoeken per minuut worden gedaan
+acl is_abuser sc0_http_req_rate gt 60
+http-request deny deny_status 429 if is_abuser
+```
+
+---
+
+## 4. Datacenter IP Blokkering met pfBlockerNG
+
+Veel kwaadaardige bots en scrapers draaien op goedkope cloud/datacenter servers (AWS, Hetzner, OVH, DigitalOcean, Linode).
+
+1. Installeer **pfBlockerNG-devel** via **System → Package Manager** in PFSense.
+2. Ga naar **Firewall → pfBlockerNG → IP → IPv4**.
+3. Voeg de ASN / Datacenter Feeds toe van bekende cloud providers (bijv. AWS, Hetzner, OVH, DigitalOcean).
+4. Zet de actie op **Deny Both** (blokkeert zowel inkomend als uitgaand verkeer naar die datacenter IP-ranges).
