Configure Remote and Local Access (Xfinity)

• For remote/external access:
  • Setup a Dynamic DNS service (like DuckDNS)
  • Forward ports 443 (HTTPS) & 80 (HTTP) to your Nextcloud machine via Xfinity router settings
  • Use DDNS domain for clients outside WiFi (e.g. https://yourname.duckdns.org)
  • Secure with HTTPS using Let’s Encrypt certificates (xda-developers+1​)
• Notes for Xfinity:
  • Use the Xfinity router’s port forwarding section
  • Update DDNS whenever your public IP changes (some DDNS clients automate this)
