Hi all, I'm wondering if anyone has experience or ideas on how to improve OpenVPN throughput with PfSense. I'll typically connect to my VPN on my laptop when on LTE, but the network performance doesn't seem to exceed 10mbps on either uploads or downloads despite seeing upwards of 50-80mbps download or 15-30mbps up locally (Verizon LTE).

The net.inet.ip.fastforwarding is a FreeBSD sysctl option, which will enable an optimization path in the network stack. It was introduced to the FreeBSD kernel in 2003. The fast forwarding path omits some checks for packets being forwarded to an outgoing interface. net.ipv4.ip_forward = 1 net.inet.ip.fastforwarding = 1. Note that the file /etc/sysctl.conf is not going to be used from systemd-207 onwards, so this will need to be move the appropriate place. Also, the “fastforwarding” line is purely based on anecdotes I found on the internet, and may not do anything at all! In fact, I think it is a BSD In order to get the forwarding speed I need I have turned on the sysctl variable net.inet.ip.fastforwarding=1 What is the ramifications of this? Will it still work with routing software like quagga or allow IPFW to still forward packets? Unless something recently changed openvpn is single threaded. If you're measuring cpu usage globally "all 4 cores" then 25% usage is one core pinned at 100%. Also things like encryption type, keys etc. greatly affect the performance of openvpn. Kernels before this commit (e.g. r295264) with "net.inet.ip.fastforwarding=1" do not exhibit this symptoms. Comment 9 George V. Neville-Neil 2016-02-11 23:24:35 UTC Can you try this without VIMAGE, and then possibly without IPSEC_NAT_T and tell me if the problem persists? Version 2.2.1-8+deb7u2 Architecture amd64 I did try all options to fix this like: 1. lack entropy ? install entropy. Now availible 4095. 2. Change MTU settings 3. Disabled compression 4. Did get a fresh test server same problem ? 5. Server has enough power I7 X980 24G RAM 6. net.inet.ip.fastforwarding=1 net.ipv4.ip_forward=1
