WireGuard Peer Config on Linux - Telnyx

Prerequisite

You have a .conf file from the Quick Start.

Step 1: Install WireGuard

ubuntu@ip-10-10-11-10:~$ sudo apt install wireguard

Step 2: Bring up the Interface

Assuming the correct config file is located at /etc/wireguard/peer1.conf

ubuntu@ip-10-10-11-10:~$ sudo wg-quick up peer1
[#] ip link add peer1 type wireguard
[#] wg setconf peer1 /dev/fd/63
[#] ip -4 address add 172.27.0.2/32 dev peer1
[#] ip link set mtu 8921 up dev peer1
[#] ip -4 route add 172.27.0.0/24 dev peer1

Step 3: Validating and Testing

ubuntu@ip-10-10-11-10:~$ sudo wg show
interface: peer1
  public key: Jt1zAJD6W2BZgOwtUsNY2KrMO0oRfUmfAEZGNEUZKiQ=
  private key: (hidden)
  listening port: 43548

peer: XYy8e5EKtE1F0fwwMgr792/9noYs53uRZBX5O3XJ4Eg=
  endpoint: 64.16.243.3:5107
  allowed ips: 172.27.0.0/24
  latest handshake: 1 minute, 28 seconds ago
  transfer: 92 B received, 2.86 KiB sent
  persistent keepalive: every 1 second

If another peer is connected to the network, it should be pingable.

ubuntu@ip-10-10-11-10:~$ ping 172.27.0.3
