+# Production Nginx Configuration for GNX Soft (Docker)
+# This configuration is for nginx running on the host machine
+# It proxies to Docker containers: backend (1086) and frontend (1087)
+#
+# IMPORTANT PORT CONFIGURATION:
+# - Backend (Django): Only accessible on port 1086 (internal)
+# - Frontend (Next.js): Only accessible on port 1087 (internal)
+# - Nginx: Public access on ports 80 (HTTP) and 443 (HTTPS)
+# - Ports 1086 and 1087 should be blocked from external access by firewall
+
+# Frontend - Next.js running in Docker on port 1087
+# All frontend requests (/) are proxied here
+upstream frontend {

+# All API requests (/api/) and admin (/admin/) are proxied here

+# ==============================================================================
+# IMPORTANT NOTES:
+# ==============================================================================
+# 1. Backend runs in Docker on port 1086 (internal only)
+# 2. Frontend runs in Docker on port 1087
+# 3. Nginx runs on host and proxies to Docker containers
+# 4. Firewall should BLOCK external access to ports 1086 and 1087
+# 5. Only nginx (ports 80, 443) should be accessible from internet
+# 6. Set INTERNAL_API_KEY environment variable in nginx config or systemd service
+# 7. Update media/static paths to match your actual deployment location
