Homelab

Network

Running a IPv4/IPv6 stack protected by Cloudflare as my ISP only offers CGNAT on IPv4.

More than 20 wired/wireless clients including IoT.

Core network was originally done with ISP router and a Cisco 3560 PoE but was migrated to a Ubiquity switch and firewall for power consumption and IPv4/IPv6 proper configuration.

Cisco switch configuration was pushed by AWX but is now decommissioned. Ubiquity APIs allow for more indepth monitoring.
