I've been doing some research into improving performance for OpenVPN and I found out about setting fastforwarding to 1 but when I tried I got the error error: net.inet.ip.fastforwarding is an unknown key and tried error: net.ipv4.ip.fastforwarding is an unknown keyand wanted to know if I needed to load a module?This is a CentoOS 6.x 64bit box.
error: net.inet.ip.fastforwarding is an unknown key
