Protectli has up to quad core and up to 6 port nic. Each NIC port can be configured as needed…1 WAN 5 LAN, 2 WAN 4 LAN, etc and you can bond them too. It also supports AES-NI and yes, suricata supports multi core/thread performance. If I remember correctly, Snort does not. I prefer the r210ii because its using only about 30w it has 8 threads and support up to, I believe, 32GB ram which between suricata and pfblocker need the extra umph to maintain full gigabit throughput within intranet and internet.
