Homelab Network Readiness

Use this skill before changing a home or small-lab network that mixes VLANs, Pi-hole or another local DNS resolver, firewall rules, and remote VPN access.

This is a planning and review skill. Do not turn it into copy-paste router, firewall, or VPN configuration unless the target platform, current topology, rollback path, console access, and maintenance window are all known.

When to Use

• Preparing to split a flat network into trusted, IoT, guest, server, or management VLANs.
• Moving DHCP clients to Pi-hole, AdGuard Home, Unbound, or another local DNS resolver.
• Adding WireGuard, Tailscale, ZeroTier, OpenVPN, or router-native VPN access.
• Reviewing whether a homelab change can lock the operator out of the gateway, switch, access point, DNS server, or VPN server.
• Turning an informal home-network idea into a staged migration plan with validation evidence.

Safety Rules

• Keep the first answer read-only: inventory, risks, staged plan, validation, and rollback.
• Do not expose gateway admin panels, DNS resolvers, SSH, NAS consoles, or VPN management UIs directly to the public internet.
• Do not provide firewall, NAT, VLAN, DHCP, or VPN commands without a confirmed platform and a rollback procedure.
• Require out-of-band or same-room console access before changing management VLANs, trunk ports, firewall default policies, or DHCP/DNS settings.
• Keep a working path back to the internet before pointing the whole network at a new DNS resolver or VPN route.
• Treat IoT, guest, camera, and lab-server networks as different trust zones until the operator explicitly chooses otherwise.
