OpenBSD router configuration

Configuration files for my OpenBSD router. The best operating system for the job, hands down.

Tested on OpenBSD 7.5 / -current.

• pf firewall
• IPv6 (dhcp6leased, rad)
• DHCP/NAT
• NTP
• Unbound for internet/local DNS resolution (DNS-over-TLS)
• WiFi via attached access point

Hardware

• Router: 4x i226-V 2.5G LAN 12th Gen Intel N100 (8GB DDR5, 128GB NVMe)
• Access Point: ASUS RT-AC68U
• Modem: ARRIS Surfboard S33 DOCSIS 3.1

Eventually I may switch the router to a Protectli Vault. I want to use coreboot however the Protectli devices are expensive and/or have slower CPUs / 1Gbps NICs.
