WireGuard® is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPSec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN.
This snap packages the wireguard-go userspace executable (https://git.zx2c4.com/wireguard-go/about/) and the wg and wg-quick binaries built from the main repo (https://git.zx2c4.com/WireGuard/about/).
With an overlay, /etc/wireguard is mapped to $SNAP_COMMON (conventionally /var/snap/wireguard-ammp/common) - so this is where you should put configuration files such as wg0.conf.
Once the config file is in place and you've connected the network-control and firewall-control interaces, run
sudo wireguard-ammp.wg-quick up wg0
to bring up the interface.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install WireGuard, simply use the following command:
