Native IPv6 on OPNsense: DHCPv6-PD & VLAN Subnets
Configure native IPv6 on OPNsense: DHCPv6 prefix delegation, SLAAC on subnetted VLANs, firewall rules, and how to verify the delegated prefix works.
Building a home network and a lab that behave, using gear a household can actually justify buying.
Set up a WireGuard road-warrior tunnel with protected keys, working DNS, scoped forwarding, and explicit IPv4/IPv6 verification.
Configure native IPv6 on OPNsense: DHCPv6 prefix delegation, SLAAC on subnetted VLANs, firewall rules, and how to verify the delegated prefix works.
Multi-WAN failover tutorials promise resilience but deliver flaky fallback, broken DNS, and dead sessions when a link flaps.
Fix Pi-hole overblocking: learn exact whitelisting, wildcard rules, and regex overrides—plus the query log step most people skip.
DoH tunnels DNS through port 443, bypassing Pi-hole entirely. Block it at the network with firewall rules, DNS hijacking, and domain poisoning.
Set up automated Home Assistant backups to a remote NAS over Samba. Off-device snapshots, no cloud fees, and a restore drill for real recovery.
Step-by-step migration: Pi-hole to AdGuard Home for native encrypted DNS, advanced filtering, and fewer moving parts. Back up, convert lists, verify.
Block IoT devices from your LAN and restrict internet by schedule using OPNsense aliases. A 30-second auditable ruleset with zero raw IPs.
When your IoT VLAN breaks discovery, an mDNS repeater is the fix. Set one up so Home Assistant sees all your devices, no firewall rules needed.
Stop juggling vendor hubs. Use Zigbee2MQTT and a USB dongle to bring every Zigbee device under local Home Assistant control—no cloud accounts needed.
Shingled magnetic recording drives can silently cripple ZFS pools with timeouts, faults, and multi-day resilvers. Here's how to spot and avoid them.
Set up a lightweight dnsdist proxy to encrypt all home DNS over HTTPS. No per-device changes—ditch ISP snooping with one privacy-respecting forwarder.
Deploy Linkwarden with Docker, preserve bookmarks as local archives, and back up its database, captures, and search data.
