Openvpn and IPV6: how to configure it without knowing the

--lport is the local port used when opening a connection. --rport is setting the remote port (the port to connect against). While --port sets both --lport and --rport to the same number (according to options.c). However, it seems the default behaviour seems to differ, depending on if UDP or TCP is used, and on which platform.

Local port defaults to random for *any* other network application, so yes, I'd call this a bug. It's highly unlikely anyone relies on the default lport being 1194 since client config samples -- including the ones shipped with openvpn -- include nobind, meaning they don't call bind() and use the OS default, which is random. Next, ask yourself if you would like to allow network traffic between client2’s subnet ( and other clients of the OpenVPN server. If so, add the following to the server config file. client-to-client push "route" This will cause the OpenVPN server to advertise client2’s subnet to other connecting clients.

Be careful to put the configuration file in the "/etc/openvpn" directory and with a ".conf" extension to be able to use the OpenVPN startup script. Note the "lport" setting is used to create several tunnels on a device with a single OpenVPN configuration file.
