Prepare files

0. install python dependency

   python3 -m pip install -r req.txt
   

1. rename db.json.template to db.json

   cp ./db.json.template ./db.json

2. change last_ip in db.json to your own network ip address.

For example in wireguard default network is 10.0.0.0/8 and server address is 10.0.0.1.

You should set "last_ip" as 10.0.0.1 and after that the script will increment ip addresses

3. in main.py you have to set BASE_DIR

   ...
   BASE_DIR = "/etc/wireguard"
   ...

Generate server and client keys

1. run key generator

   python3 main.py --name <client-name>
   

2. copy output to wg0.conf

   output look like

   udwfMasdsadsadsddsasdkjasoidhughfasd=
   
   # <client-name>
   [Peer]
   PublicKey = udwfMasdsadsadsddsasdkjasoidhughfasd=
   
   AllowedIPs = 10.0.0.29/32
   
   /<BASE_DIR>/confs/<client-name>_wg.conf
   

   You have to copy

   # <client-name>
   [Peer]
   PublicKey = udwfMasdsadsadsddsasdkjasoidhughfasd=
   
   AllowedIPs = 10.0.0.29/32
   

   and paste it to wireguard config file (by default /etc/wireguard/wg0.conf)

3. send /<BASE_DIR>/confs/_wg.conf to client

4. restart wireguard service

   systemctl restart wg-quick@wg0
   

Client

Install wireguard https://www.wireguard.com/install

Connect to server

wg-quick up <client-name>_wg.conf

Drop connection

wg-quick down <client-name>_wg.conf
