3. Create private and public keys

   Code Block
   wg genkey | tee privatekey | wg pubkey > publickey

4. Create the config file
   Now you can configure the server, just add a new file called /etc/wireguard/wg0.conf. Insert the following configuration lines and replace the <server-private-key> placeholder with the previously generated private key.

5. Code Block
   vi /etc/wireguard/wg0.conf [Interface] PrivateKey=<server-private-key> Address=10.99.0.1/32 SaveConfig=true PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE; PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o wlan0 -j MASQUERADE; ListenPort = 51821

6. Configure the wireguard client
   
   Now, we need to configure the client. Create a new file called /etc/wireguard/wg0.conf. Insert the following configuration lines and replace the <client-private-key> placeholder with the previously generated private key.

   You need to insert a private IP address for the <client-ip-address> in the same subnet like the server's IP address. Next, replace the <server-public-key> with the generated servers public key. And also replace <server-public-ip-address> with the IP address where the server listens for incoming connections.Note that if you set the AllowedIPs to

   0.0

   Code Block
   [Interface] PrivateKey = <client-private-key> Address = 10.99.0.

   0/0 the client will route ALL traffic through the VPN tunnel. That means, even if the client will access the public internet, this will break out on the server-side. If you don't want route all traffic through the tunnel, you need to replace this with the target IP addresses or networks.

   Code Block
   [Interface] PrivateKey = <client-private-key> Address = <client-ip-address>/<subnet> SaveConfig = true [Peer] PublicKey = <server-public-key> Endpoint = <server-public-ip-address>:51820 AllowedIPs = 0.0.0.0/0

7. Start and test
   enable the wg0 interface with the following command

8. Code Block
   wg-quick up wg0

   You can check the status of the connection with this command.

   Code Blockwg

   2/24 [Peer] PublicKey = <server-public-key> AllowedIPs = 10.99.0.0/24 Endpoint = <server-public-ip-address>:51821

9. Open ports (UDP) for wireguard on your router.

10. Start and test
    enable the wg0 interface with the following command

11. Code Block
    wg-quick up wg0 [#] ip link add wg0 type wireguard [#] wg setconf wg0 /dev/fd/63 [#] ip -4 address add 10.99.0.1/24 dev wg0 [#] ip link set mtu 1420 up dev wg0 [#] iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE;

    You can check the status of the connection with this command.

    Code Block

    [root@pikvm ~]# wg interface: wg0 public key: K9aP9W9TW/bfdaGQA2fSFBZh6ZZy198Q= private key: (hidden) listening port: 51821 [root@pikvm ~]# ifcongif -a -bash: ifcongif: command not found [root@pikvm ~]# ifconfig -a lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (Local Loopback) RX packets 99 bytes 8158 (7.9 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 99 bytes 8158 (7.9 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 wg0: flags=209<UP,POINTOPOINT,RUNNING,NOARP> mtu 1420 inet 10.99.0.1 netmask 255.255.255.0 destination 10.99.0.1 unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 1000 (UNSPEC) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255 inet6 fe80::e65f:1ff:fe87:f396 prefixlen 64 scopeid 0x20<link> ether e4:5f:01:87:f3:96 txqueuelen 1000 (Ethernet) RX packets 1505204 bytes 36789964 (35.0 MiB) RX errors 0 dropped 1224409 overruns 0 frame 0 TX packets 110425 bytes 8452065 (8.0 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

    Next, you need to add the client to the server configuration file. Otherwise, the tunnel will not be established. Replace the <client-public-key> with the clients generated public key and the <client-ip-address> with the client's IP address on the wg0 interface.

    Code Block
    wg set wg0 peer <client-public-key> allowed-ips <client-ip-address>/32

    Now you can enable the wg0 interface on the server.

    Code Block
    wg-quick up wg0

    Code Block
    wg

12. Configure auto-start
