What is homelab-network-readiness and what does it help with?
homelab-network-readiness is a planning and validation framework for homelab network upgrades involving VLANs, local DNS resolvers, firewall rules, and remote access. It guides you through required inventory, trust zones, and staged migration steps to avoid locking yourself out of critical infrastructure, and includes safety rules, anti-patterns, and a review checklist to confirm your changes won't break management access or recovery paths.
What is a homelab network VLAN setup checklist?
homelab-network-readiness provides a VLAN setup checklist that helps you segment your network into VLANs with proper trust boundaries. The checklist covers inventory of devices, definition of trust zones (management, guest, IoT, production), DHCP and DNS configuration per VLAN, firewall rules between zones, and validation steps before applying changes to ensure you maintain access to critical infrastructure.
How should I plan network segmentation before router changes?
homelab-network-readiness emphasizes planning network segmentation before router changes by first documenting your current topology, identifying trust boundaries, staging changes incrementally, and creating rollback procedures. The framework prioritizes avoiding single points of failure—especially for DNS and management access—and requires you to validate each segment's connectivity and firewall rules before moving to the next change.
How do I set up local DNS filtering without a single point of failure?
homelab-network-readiness guides DNS filtering setup by recommending multiple resolver instances (Pi-hole, AdGuard, or similar) across different VLANs or devices, configuring DHCP failover to secondary resolvers, and testing migration paths before cutover. The framework ensures you don't create a single point of failure by validating that clients can reach at least one resolver and that your recovery path doesn't depend solely on the DNS service you're replacing.
What remote access VPN homelab preparation steps should I follow?
homelab-network-readiness covers remote VPN access preparation by documenting which VLANs and services should be accessible remotely, configuring route restrictions to prevent accidental exposure of all internal traffic, testing access from outside your network before full deployment, and maintaining a separate management access path independent of the VPN. This ensures you can recover if the VPN configuration breaks.
What safety risks and rollback procedures should I review?
homelab-network-readiness emphasizes reviewing safety risks such as locking yourself out of management access, breaking DNS resolution, or creating firewall rules that isolate critical services. The framework requires you to document rollback procedures for each change, maintain out-of-band access (console, secondary network), test recovery paths before deployment, and stage changes incrementally so you can identify and revert problems quickly.

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
