General

Overview

Wireguard® is a modern and simple VPN protocol, which additionally convinces by its performance.

Advantages

Wireguard does without some complex procedures for key exchange and is therefore easier to handle than IPSec.

Due to the integration into the Linux kernel, a high-performance and resource-saving processing is possible compared to OpenVPN.

Gut zu wissen
The OpenVPN integration in the Securepoint UTM is also very performant.
The speed disadvantage of SSL-VPN connections compared to WireGuard connections is therefore not as serious as can be observed with competitors.

Disadvantages

Settings like routes, DNS etc. cannot be "pushed" like with OpenVPN

This makes the management of Roadwarriors much more complex

Connection

Communication takes place via a freely selectable UDP port and uses IPv4 and IPv6 to transport the data packets.

The handling between the two peers is very similar to OpenSSH.
"Peers" must first exchange their PublicKeys and can then "simply" exchange data further on.
The exchange of PublicKeys is explicitly not part of the WireGuard specification and must be performed manually.

A PublicKey must identify a peer unmistakably.
Multiple uses are not practical.
For better protection, a preshared key can also be used.

Dashboard

The dashboard shows the connection status of each peer of a connection as well as the name, key and IP of a user and the associated user groups.

For a better overview, individual sections can be hidden in the overview if necessary:

NAT

WireGuard can send a keepalive.
This keeps connections open on NAT routers.

Since the communication only runs via a UDP port, WireGuard is not susceptible to NAT related problems.

Widget

There is a widget in the admin interface for the overview of WireGuard connections. Further information can be found in the Wiki article UTM Widget.
