Skill 03
Networking
Business and homelab networks using VLANs, managed switching, VPNs, DNS, and network diagnostics.
01
ProGranite network
I redesigned and deployed ProGranite’s network using a UniFi Dream Machine Pro, Layer 3 switches, wireless access points, and fiber uplinks. The project increased available throughput from 500 Mbps to 1 Gbps and improved segmentation and reliability.
- VLAN segmentation and inter-VLAN policies
- Layer 3 switching and fiber uplinks
- Wireless access-point management
- VPN remote access
- Static addressing for CNC and business systems
02
Homelab networking
The homelab is segmented by function and supports virtualized servers, storage, container workloads, and externally published services. I manage internal DNS, TLS routing, VPN connectivity, firewall rules, and service troubleshooting.
- Tagged and untagged VLANs
- Traefik reverse proxy and certificate management
- WireGuard and Tailscale connectivity
- Cloudflare DNS and proxy services
- NFS storage traffic between systems
03
Diagnostics
I use packet and service-level tools to identify faults across addressing, name resolution, routing, firewall rules, and application connectivity.
- ping, traceroute, dig, and nslookup
- Nmap and netcat
- tcpdump and Wireshark
- Switch, firewall, and service logs
