Why it mattered
The edge firewall needed to become a stable routing, DNS, security, and ingress control point for the whole lab.
OPNsense Edge Firewall
Firewall, routing, DNS/DHCP, certificate, IDS, and public ingress patterns without exposing private details.
What changed
The firewall project shows practical network administration and security-minded change control.
Build summary
- Operated OPNsense as the gateway and firewall for segmented lab networks.
- Documented DNS, DHCP, certificate, and ingress patterns at a sanitized level.
- Used change notes to track fixes and prevent stale service references.
