Guide réseau pour serveurs domestiques

Good networking turns a pile of services into a tidy, reachable, secure system. Here are the building blocks.

Give services a static home

Assign your server a static IP or a DHCP reservation so its address never changes. Everything else depends on this.

Clean URLs with a reverse proxy

Nobody wants to remember 192.168.1.50:8096. A reverse proxy like Nginx Proxy Manager, Traefik or Caddy maps friendly names (jellyfin.home.example.com) to your services and handles HTTPS certificates automatically.

jellyfin.home.example.com  →  192.168.1.50:8096
nextcloud.home.example.com →  192.168.1.50:8080

Learn the concept in the reverse proxy glossary entry.

Local DNS

Run Pi-hole or AdGuard Home as your local DNS to resolve those friendly names and block ads network-wide at the same time.

Reaching your server from outside

Do not carelessly forward ports. Instead:

1. Best: a VPN — Tailscale or WireGuard — so you're "inside" your network from anywhere.
2. If you must expose services: a reverse proxy with HTTPS and strong authentication, and only the one port (443) open.

Segment with VLANs (optional)

As your setup grows, VLANs let you isolate untrusted devices (IoT gadgets, guests) from your server and personal devices. A managed switch makes this possible.

A sensible target setup

• Static IP for the server
• Local DNS via Pi-hole
• Reverse proxy with automatic TLS
• Tailscale/WireGuard for remote access
• VLAN for IoT once you're ready

Get these right and your home server will be both convenient and secure.
