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: 10.123.45.141
Public interface: ens3
WireGuard interface name: wg0
Server WireGuard IPv4: 10.66.66.1
Server WireGuard IPv6: fd42:42:42::1
Server WireGuard port [1-65535]: 54004
First DNS resolver to use for the clients: 8.8.8.8
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...
