==Summary==


'''Virtual Private Network''' ('''VPN''') is a method for secure data transfer through unsafe public networks. This page is an overview of different types of VPNs that can be used with RUT routers.

'''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 RUTxxx routers. For a more in depth guide refer to our '''[[OpenVPN configuration examples]]''' page.
* [[IPsec_RUTOS_configuration_example|IPsec cofiguration example]]
 
* [[ZeroTier One VPN configuration RutOS|ZeroTier One VPN configuration example]]
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.

* [[Setting up a GRE over IPsec tunnel between RUTOS devices|GRE over IPsec Tunnel]]
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).

After setting any of these parameters press the '''Save''' button or else the changes will not be applied. Some of the selected parameters will be shown in the configuration list table. You should also be aware of the fact that the router will launch a separate OpenVPN service for every configuration entry (if it is defined as active at the time, of course) so the router has the ability to act as server and client at the same time.
 
===OpenVPN Server===

This section is an overview of OpenVPN Server configuration.
 
[[Image:Services vpn openvpn server.PNG]]
 
The figure above is an example of a configured OpenVPN Server instance that uses the UDP protocol and TLS authentication. As you can see, the configuration is similar to OpenVPN Client but with a few key differences. Comprehensible explanations on each field are presented in the table below:

'''*''' You can find detailed instructions on how to generate your own TLS certificates '''[[How to generate TLS certificates (Windows)?|here]]'''.
 
===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.

==IPsec==
 
The IPsec protocol client enables the router to establish a secure connection to an IPsec peer via the Internet. IPsec is supported in two modes - transport and tunnel. Transport mode creates a secure point to point channel between two hosts. Tunnel mode can be used to build a secure connection between two remote LANs serving as a VPN solution.
 
IPsec system maintains two databases: Security Policy Database (SPD) which defines whether to apply IPsec to a packet or not and specify which/how IPsec-SA is applied and Security Association Database (SAD), which contains a Key of each IPsec-SA.
 
The establishment of the Security Association (IPsec-SA) between two peers is needed for IPsec communication. It can be done by using manual or automated configuration.
 
'''NOTE''': the router starts establishing a tunnel when data is sent from the router to a remote site over the tunnel. The Keep Alive feature is used for automatic tunnel establishment.
----
For a more in-depth configuration example, visit the '''[[IPsec configuration examples]]''' page.
----
To create a new IPsec instance, go to the IPsec tab, type in a name for your new instance in the text field below the IPsec tab and press the '''Add''' button next to it.
 
'''NOTE''': You can create a maximum of 5 IPsec instances.

Transport mode is usually used when another tunneling protocol (such as [[VPN#GRE_Tunnel|GRE]], [[VPN#L2TP|L2TP]] (click '''[[L2TP over IPsec|here]]''' for a configuration example on '''L2TP over IPsec''')) is used to first encapsulate the IP data packet, then IPsec is used to protect the GRE/L2TP tunnel packets.

'''Phase''' 1 and '''Phase 2''' must be configured in accordance with the IPSec server configuration, thus algorithms, authentication and lifetimes of each phase must be identical.

==GRE Tunnel==
 
'''GRE''' (Generic Routing Encapsulation RFC2784) is a solution for tunneling RFC1812 private address-space traffic over an intermediate TCP/IP network such as the Internet. GRE tunneling does not use encryption it simply encapsulates data and sends it over the wide area network (WAN).
 
 
[[Image:Services vpn gre tunnel scheme.PNG]]
 
In the example network diagram two distant networks LAN1 and LAN2 are connected. To create A GRE tunnel the user must know the following parameters:
 
* Source and destination IP addresses
* Tunnel’s local IP address
* Distant network’s IP address and Subnet mask
 
To create a new GRE instance, go to the GRE Tunnel tab, type in a name for your new instance in the text field below the GRE Tunnel tab and press the '''Add New''' button next to it.
The newly created instance will be disabled and unconfigured. To configure it press the '''Edit''' button located next to it. This action will redirect you to the instance’s GRE Tunnel Configuration window.

==PPTP==
 
'''Point-to-Point Tunneling Protocol (PPTP)''' is a protocol (set of communication rules) that allows corporations to extend their own corporate network through private "tunnels" over the public Internet. Effectively, a corporation uses a wide-area network as a single large local area network. A company no longer needs to lease its own lines for wide-area communication but can securely use the public networks.
 
For a more in-depth configuration example, visit the '''[[PPTP configuration examples]]''' page.
 
===PPTP Client===
----
To create a new PPTP instance, go to the PPTP tab, select the Role (server or client) of your instance, type in a name in the '''New configuration name''' field and press the '''Add''' button next to it. The newly created instance will be disabled and unconfigured. To configure it click the '''Edit''' button located next to it. This action will redirect you to the instance’s PPTP Configuration window.

==L2TP==
 
In computer networking, '''Layer 2 Tunneling Protocol (L2TP)''' is a tunneling protocol used to support virtual private networks (VPNs). It is more secure than PPTP but, because it encapsulates the transferred date twice, but it is slower and uses more CPU power.

The newly created instance will be disabled and unconfigured. To configure it press the '''Edit''' button located next to it.
