This commit resolves connectivity issues for www.directlx.dev by:
1. Add nginx firewall configuration (host_vars/nginx.yml)
- Allow ports 80/tcp (HTTP) and 443/tcp (HTTPS)
- Enables NPM to proxy traffic to nginx backend
2. Add www.directlx.dev DNS record via Pi-hole
- Configure playbooks/configure-directlx-dev-dns.yml
- Route www.directlx.dev → NPM (192.168.200.71)
- NPM then proxies to nginx (192.168.200.65)
Problem: After firewall changes, nginx server only allowed SSH (port 22),
blocking HTTP/HTTPS from NPM. Additionally, Pi-hole had no DNS record for
www.directlx.dev subdomain.
Solution: Applied firewall rules and DNS configuration to complete the
proxy chain: Browser → Pi-hole DNS → NPM → nginx.
