LuntikWG is a simplified version of the WireGuard-GUI. Loads any *.conf configuration and adapts it to VPN-Up/Down events to work correctly with VPN/DNS. There is an autostart on reboot.
The connection is raised immediately after downloading the *.conf file. The connection can be stopped or restarted at any time. VPN indication: yellow - waiting/lost, green - active. Tested and works with network.service/net_applet and NetworkManager/nm-applet in Mageia-8/9.
Note: Don't forget to open the iptables ports required for configurations. If you can't decide on the ports, temporarily disable iptables/ip6tables in the Mageia Control Center. Unlike OpenVPN, WireGuard is especially sensitive to IPv6. To use free WireGuard configurations, at least iproute2, resolvconf, iptables/ip6tables, systemd, active ipv4/ipv6 forwarding and a kernel module are required.
For tests, you need to clear all the rules to allow the main chains of iptables/ip6tables:
iptables -F; iptables -P INPUT ACCEPT; iptables -P FORWARD ACCEPT; iptables -P OUTPUT ACCEPT
ip6tables -F; ip6tables -P INPUT ACCEPT; ip6tables -P FORWARD ACCEPT; ip6tables -P OUTPUT ACCEPT
