<b>OpenVPN</b> 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. It is often regarded as being the most universal VPN protocol because of its flexibility, support of SSL/TLS security, multiple encryption methods, many networking features and compatibility with most OS platforms. | <b>OpenVPN</b> 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.

Summary
Virtual Private Network (VPN) is a method of connecting multiple private networks across the Internet. VPNs can serve to achieve many different goals, but some of its main purposes are:
- access between remote private networks;
- data encryption;
- anonymity when browsing the Internet.
This page is an overview of the different types of VPNs supported by {{{name}}} devices.
OpenVPN
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. It is often regarded as being the most universal VPN protocol because of its flexibility, support of SSL/TLS security, multiple encryption methods, many networking features and compatibility with most OS platforms.
{{{name}}} devices run OpenVPN version 2.4.5.
OpenVPN client
An OpenVPN client is an entity that initiates a connection to an OpenVPN server. To create a new client instance, go to the Services → VPN → OpenVPN section, select Role: Client, enter a custom name and click the 'Add' button. An OpenVPN client instance with the given name will appear in the "OpenVPN Configuration" list.
To begin configuration, click the button that looks liek a pencil next to the client instance. Refer to the figure and table below for information on the OpenVPN client's configuration fields:

TTL is a field in the IP packet header which is initially set by the sender and decreased by 1 on each hop. When it reaches 0 it is dropped and the last host to receive the packet sends an ICMP "Time Exceeded" message back to the source. |
Outbound key | integer [0..65535]; default: none | A key used to identify outgoing packets. This value should match the "Inbound key" value set on the opposite GRE instance or both key values should be omitted on both sides. |

An L2TP server instance with the given name will appear in the "L2TP Configuration" list. Only one L2TP server instance is allowed to be added.
A server needs to have a public IP address in order to be available from the public network (the Internet).
To begin configuration, click the button that looks like a pencil next to the server instance. Refer to the figure and table below for information on the L2TP server's configuration fields:
Field | Value | Description |
---|---|---|
Enable | off | on; default: off | Turns the L2TP instance on or off. |
Local IP | ip; default: 192.168.0.1 | IP address of this L2TP network interface. |
Remote IP range begin | ip; default: 192.168.0.20 | L2TP IP address leases will begin from the address specified in this field. |
Remote IP range end | ip; default: 192.168.0.30 | L2TP IP address leases will end with the address specified in this field. |
User name | string; default: user | Username used for authentication to this L2TP server. |
Password | string; default: pass | Password used for authentication to this L2TP server. |
L2TP Client's IP | ip; default: none | Assigns an IP address to the client that uses the adjacent authentication info. This field is optional and if left empty the client will simply receive an IP address from the IP pool defined above. |
WireGuard
WireGuard is simple, fast, lean, and modern VPN that utilizes secure and trusted cryptography. It intends to be more performant than OpenVPN. WireGuard is designed as general purpose VPN, fit for many different circumstances and while it is currently under heavy development, it already might be regarded as the most secure, easiest to use, and simplest VPN solution.
Note: WireGuard is additional software that can be installed from the Services → [[{{{name}}} Package Manager|Package Manager]] page.
WireGuard works by adding an interface which acts as a tunnel. To create one enter its name and click the Add button.
To configure it click the Edit button.
General Instance Settings
This section contains General settings of created WireGuard Instance. Here you can find its Public and Private keys and generate them, specify Port and IP addresses for communication.
Field | Value | Description |
---|---|---|
Enable | off | on; default: off | Turns WireGuard Instance on or off. |
Private Key | string; default: none | Private Key used in authentication. |
Public Key | string; default: - | Public Key used in authentication. |
Generate | -(interactive button) | Click to generate Public Key and Private Key. |
Listen Port | integer [0..65535]; default: none | Specify port to listen for incomming connections. It will be set to a random integer if left empty. |
IP Addresses | ip; default: none | A single IP address or a list of them for this instance associated with public keys. |

Advanced Settings section contains Metric and MTU configuration for this WireGuard interface.
Field | Value | Description |
---|---|---|
Metric | positive integer; default: none | Specify metric for this tunnel interface. Lower number means higher priority. |
MTU | integer [1280..1420]; default: none | Maximum Transmission Unit for this tunnel interface. |
