LAN Side Interface Mapping

Problem

Edge devices must place Ethernet ports into the right security zones (LAN, DMZ, VPN) quickly and safely. Manual zone assignment is slow and error-prone as topologies grow.

How it works

• The platform models zone types such as VPN, DMZ, cloud, and public/private routing domains.
• Physical or VLAN interfaces are assigned into zone groups so traffic is segmented and isolated correctly.
• Automated zone assignment reduces repetitive CLI/config work when ports are added or roles change.
• Routing and services then attach to the zone model instead of hard-coded port names.

What I built / owned

• Designed and deployed LAN-side interface control for flexible Ethernet assignment across LAN, DMZ, and VPN zones.
• Enabled secure segmentation and scalable multi-zone topologies.
• Automated zone assignment to cut configuration time substantially.

Impact

Reduced configuration time by about 40% while improving segmentation consistency across multi-zone edge deployments.
