I have users who are uploading over WAN/VPN link to FreeBSD file servers and speed averages 1.9Mbits. To non FreeBSD servers we would see speeds of aprox 5-6Mbits. Previously in a similar situation over a WAN link with no VPN I have used net.inet.tcp.inflight.enable to greatly increase the speed. I was wondering if there is something similar to the above sysctl that's more specific to WAN where the traffic is crossing a VPN? Or if anyone has any other suggestions to tweak? Currently FreeBSD 7.4 is been used and we're not currently in a position to upgrade. Kind Regards, Brian Hughes
