WireGuard ACTIVE Peer Status: Clients 3, Servers 2In lieu of the NVRAM variables that can retain OpenVPN Client/Server configurations across reboots, this script uses SQL database
'/opt/etc/wireguard.d/Wireguard.db' for the WireGuard configuration directives.
The contents of the WireGuard configuration database will be used when say 'wg13.conf' is activated - assuming that you have used say the appropriate WireGuard Web configurator such as Mullvad's to create the Local IP address and Public/Private key-pair for the remote Peer. e.g
start wg13The script supports several commands:
wgm {start|stop|restart|check|install} [ [client [policy] |server]} [wg_instance] ]
wgm start 0
Initialises remote peer 'client' 'wg0' solely to remain backwards compatibilty with original
wgm start client 0
Initialises remote peer 'client' 'wg0'
wgm start 1
Initialises local peer 'server' 'wg1' solely to remain backwards compatibilty with original
wgm start server 1
Initialises local peer 'server' 'wg21' uses interface naming convention as per OpenVPN e.g. tun21
wgm start client 1
Initialises remote peer 'client' 'wg11' uses interface naming convention as per OpenVPN e.g. tun11
wgm start client 1 policy
Initialises remote peer 'client' 'wg11' in 'policy' Selective Routing mode
wgm stop client 3
Terminates remote peer 'client' 'wg13'
wgm stop 1
Terminates local peer 'server' 'wg21'
wgm stop
Terminates ALL ACTIVE peers (wg1* and wg2* etc.)
wgm start
Initialises ALL peers (wg1* and wg2* etc.) defined in the configuration file where Auto=Y or Auto=Pand if the install is successful, there should now be a couple of simple aliases
e.g.
wg_manager and wgm to start the script (NOTE 'wg_manager' is available immediately, but 'wgm' will require you to logoff/login to refesh your terminal profile.)
The following (WireGuard Manager) is the alias to invoke the script e.g.
wgm peer list Lists the defined Peers in the config The sub-commands for peer allow manipulation of the Auto= value etcAn example of the enhanced WireGuard Peer Status report showing the names of the Peers rather than just their cryptic Public Keys
wgm show
interface: wg21 (# Martineau Host Peer 1)
public key: j+aNKC0yA7+hFyH7cA9gIJ9+Ms05G3q4kYG/JkBwAU=
private key: (hidden)
listening port: 1151
peer: wML+L6hN7D4wx+E1SA0K4/5x1cMjlpYzeTOPYww2WSM= (# Samsung Galaxy S8)
allowed ips: 10.50.1.88/32
peer: LK5/fu1iX1puR7+I/njj6W88Cr6/tDZhuaKp3XKM/R4= (# Device iPhone12)
allowed ips: 10.50.1.90/32NOTE: Currently, if you start say three WireGuard remote Peers concurrently and none of which are designated as Policy Peers, ALL traffic will be forced via the most recent connection, so if you then terminate that Peer, then the least oldest of the previous Peers will then have ALL traffic directed through it. Very crude fall-over configuration but may be useful.
For hosting a 'server' Peer (wg21) you can use the following command to generate a Road-Warrior Private/Public key-pair and auto add it to the 'wg21.conf'
wgm create Nokia6310i
Creating Wireguard Private/Public key pair for device 'Nokia6310i'
Device 'Nokia6310i' Public key=uAMVeM6DNsj9rEsz9rjDJ7WZEiJjEp98CDfDhSFL0W0=
Press y to ADD device 'Nokia6310i' to 'server' Peer (wg21) or press [Enter] to SKIP.
y
Adding device Peer 'Nokia6310i' to RT-AC86U 'server' (wg21) and WireGuard configand the resulting entry in the WireGuard 'server' Peer config 'wg21.conf' - where 10.50.1.125 is derived from the DHCP pool for the 'server' Peer
e.g.
Peers (Auto=P - Policy, Auto=X - External i.e. Cell/Mobile)
Server Auto Subnet Port Annotate
wg21 Y 10.50.1.1/24 11501 # RT-AC86U Server 1and the next avaiable IP with DHCP pool prefix '10.50.1' e.g. .125 is chosen as .124 is already assigned when the Peer is appended to 'wg21.conf'
# Nokia6310i
[Peer]
PublicKey = uAMVeM6DNsj9rEsz9rjDJ7WZEiJjEp98CDfDhSFL0W0=
AllowedIPs = 10.50.1.125/32
# Nokia6310i Endand the cosmetic Annotation identification for the device '# Device Nokia6310i' is appended to the WireGuard Peer configuration
To import the device Nokia6310i into the WireGuard App on the mobile device or tablet, rather than manually enter the details, or import the text file using a secure means of transfer, it is easier to simply display the QR Code containing the configuration and point the phone's/tablet's camera at the QR Code! ;-)
