OpenWrt / Homelab Network Administration

Router administration, internal service support, and careful network change management.

Project Goal

Maintain a reliable small-lab network while improving visibility and reducing avoidable downtime.

This work centered on administering an OpenWrt-based homelab network and the services that depend on it. The public write-up is intentionally sanitized: it focuses on process, tooling, and troubleshooting approach rather than private internal addresses, sensitive hostnames, or firewall specifics.

Key Responsibilities

High-level tasks involved in the environment.

  • Maintained router software and verified service health after updates
  • Worked with LAN-side services such as DNS, DHCP, and remote administration workflows
  • Used SSH-based management and documentation to reduce configuration mistakes
  • Coordinated network monitoring and log visibility with the rest of the homelab stack

High-Level Steps

Workflow used to manage router and network changes safely.

  1. Reviewed router health and current service state before making changes.
  2. Applied updates and configuration changes using repeatable administration steps.
  3. Validated DNS, DHCP, and internal service reachability after the maintenance window.
  4. Used monitoring and centralized logs to catch regressions or connectivity problems quickly.
  5. Documented the workflow so future network maintenance would be safer and easier to repeat.

Skills Demonstrated

Concepts shown by the project.

  • Router administration and change validation
  • DNS, DHCP, and internal service troubleshooting
  • Operational documentation for repeatable maintenance
  • Network-aware troubleshooting across router, host, and service layers

Future Improvements

Possible next steps.

  • Add a sanitized network diagram to the public documentation
  • Document backup and rollback procedures in more detail
  • Expand alerting around service reachability and admin-surface changes
