Alix, ipSec tunnel + vpn1411 accelerator = no gain



  • Hello there!

    I am using ipsec site2site with 3DES, and the CPU reaches 100% when performing at ~14 Mbps. So I bought the vpn1411 accelerator, hoping I would see some improvement - but I don't.
    Do I need to change some setting? Executing: "openssl speed -evp aes-128-cbc" does show massive improvement, but I don't see a lower CPU usage when using may ~14 Mbps WAN uplink.
    I know there is a setting for OpenVPN mode, but I don't have any "hardware crypto" setting in my ipsec screen. What am I doing wrong?

    TIA
