Currently, we have: Servers v2.3: comp-lzo no Clients: comp-lzo yes

Why OpenVPN is so slow? (cool story) — LowEndTalk OpenVPN is in active development for 3 years already, 2.0 version is almost released. One of the developers decides to add some code for socket buffer, I think to unify buffer sizes between OSes. In Windows, something goes wrong with adapters' MTU if custom buffers sizes are set, so finally it transformed to the following code: OpenWrt Project: OpenVPN extras Enable CCD on VPN server, add route to client side LAN, push route to server side LAN, selectively disable gateway redirect.. mkdir-p / etc / openvpn / ccd cat << EOF > / etc / openvpn / ccd / client ifconfig-push iroute push-remove redirect-gateway EOF cat << EOF >> / etc / openvpn / server.conf client-config-dir ccd route 255

OpenVPN 安装和配置

Explanation: compression. Compression might increase your internet speed and OVPN therefore supports it. However, there are some security issues with having compression enabled and visiting websites over HTTP. With adaptive compression, OpenVPN will periodically sample the compression process to measure its efficiency. If the data being sent over the tunnel is already compressed, the compression efficiency will be very low, triggering openvpn to disable compression for a period of time until the next re-sample test. –management IP port [pw-file] Aug 06, 2019 · Generally this impact is minimal, and enabling compression is beneficial for nearly any usage of OpenVPN over the Internet. For high speed connections, such as the usage of OpenVPN across a LAN, high speed low/latency WAN, or local wireless network, this may be undesirable, as the delay added by the compression may be more than the delay saved OpenVPN can optionally use the LZO compression library to compress the data stream. Port 1194 is the official IANA assigned port number for OpenVPN. Newer versions of the program now default to that port. For now, it is advised that users of the OpenVPN Access Server and the OpenVPN Connect Client software disable the use of compression. This effectively makes exploiting this vulnerability impossible. This can very easily be done on the OpenVPN Access Server by going to the admin web interface, and going to Advanced VPN.
