What to Look For
Key factors to consider before buying on AliExpress
Dual 2.5Gb Ethernet is the minimum. Intel i226-V NICs are preferred for FreeBSD driver support. Realtek 8125 NICs work but need additional driver installation.
N100 handles 1Gb routing easily and 2.5Gb with IDS/IPS. N305 or Core i3 for multi-gigabit WireGuard VPN throughput.
N100 draws 6-10W at idle, 15-25W under load — excellent for 24/7 operation. Active cooling is preferred for sustained routing workloads.
