WireGuard: Difference between revisions

Revision as of 11:41, 10 December 2024

Wireguard is loved FOSS software that is simpler and smaller and WAY FASTER than OpenVPN so, let's have at it.

Installation

Simplest installation can be done with this script. I'm tired and not sure why there is not a dedicated PPA as the version baked into Ubuntu is f'in old... so let's just try this...

curl -O https://raw.githubusercontent.com/angristan/wireguard-install/master/wireguard-install.sh
chmod +x wireguard-install.sh
./wireguard-install.sh

My choices:

 🌵 m@bitpost  [~] sudo ./wireguard-install.sh
Welcome to the WireGuard installer!
The git repository is available at: https://github.com/angristan/wireguard-install

I need to ask you a few questions before starting the setup.
You can keep the default options and just press enter if you are ok with them.

IPv4 or IPv6 public address: 136.47.226.130
Public interface: enp10s0f0
WireGuard interface name: wg0
Server WireGuard IPv4: 192.168.22.199
Server WireGuard IPv6: fd42:42:42::1
Server WireGuard port [1-65535]: 53
First DNS resolver to use for the clients: 192.168.22.1
Second DNS resolver to use for the clients (optional): 1.1.1.1

WireGuard uses a parameter called AllowedIPs to determine what is routed over the VPN.
Allowed IPs list for generated clients (leave default to route everything): 0.0.0.0/0,::/0 
Okay, that was all I needed. We are ready to setup your WireGuard server now.
You will be able to generate a client at the end of the installation.
Press any key to continue...

Something went wrong...

* Applying /etc/sysctl.conf ...
net.ipv4.ip_forward = 1
Job for [email protected] failed because the control process exited with error code.
See "systemctl status [email protected]" and "journalctl -xeu [email protected]" for details.
