| − | | + | ** [[OpenVPN configuration examples]] |
| − | '''OpenVPN''' is an open-source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. This section is an overview of the OpenVPN section of RUT routers. For a more in depth guide refer to our '''[[OpenVPN configuration examples]]''' page.
| + | ** [[IPsec configuration examples]] |
| − | | + | ** [[L2TP configuration examples]] |
| − | The default OpenVPN Configuration list is empty, so you have to define your own configuration to establish any sort of OpenVPN connection. OpenVPN configurations can have one of two roles: '''client''' or '''server'''. Let’s start with an OpenVPN client. To create it, enter the desired instance name in the '''New configuration name''' field, select the instance’s role from the '''Role''' list and press the '''Add New''' button.

| − | | + | ** [[Vpnbook.com VPN configuration|vpnbook.com]] |
| − | Once you’ve added a new OpenVPN instance there is no need to press the '''Save''' button, since the '''Add New''' button both creates and saves the new instance. By default the instance will be disabled and unconfigured. In order to establish an OpenVPN connection you must Enable your instance, enter an OpenVPN server address, choose an authentication method and a few other things, all of which can be configured in the '''Settings''' window, which can reached by pressing the '''Edit''' button next to your OpenVPN instance (as shown in the figure above).

| − | | style="text-align: left; vertical-align: top;" | Push options are a way to “push” user defined routes to connecting clients’ routing tables. In the example above, the server will push the route of 192.168.1.0 network with the 255.255.255.0 netmask to connecting clients. Therefore, the client will be able to reach devices in the 192.168.1.0 network. This is useful when a client needs to reach devices located in the OpenVPN server’s LAN.

| − | ===TLS Clients===
| |
| − | ----
| |
| − | TLS Clients is a way to more specifically differentiate clients by their '''Common Name (CN)''' found in the client certificate file. It can be used to assign specific VPN addresses to specific clients and bind them to their LAN addresses so that other device‘s in the client‘s LAN can be reached from the server or other clients.
| |
| − | | |
| − | The TLS Clients section can be found in the OpenVPN Server configuration window, provided that the OpenVPN server uses TLS or TLS/Password authentication methods. To create a new TLS client, type in the new client‘s name in the text field found bellow the TLS Clients tab and press the '''Add''' button.
