Post by: mitchskis on March 02, 2016, 06:40:00 pm

Are VPN accelerator cards still a thing in the x86 firewall industry? Does OPNsnese support any such hardware?

Most CPUs come with AES-NI instructions and this will provide superior performance when using AES VPNs. The days of addon cards for VPN are over with such CPUs as these cards only serve to increase latency today - PCI bus to CPU and back.
Get a CPU with AES instructions instead.
