[Solved] Backup default route via wireguard VPN

Hello,

I use a wireguard VPN as the default route configured via systemd-networkd like this config: https://wiki.archlinux.org/title/WireGu … d-networkd
Rarely my wireguard server has issues and I need to connect manually to another wireguard server to have internet access.
Is there a way to configure multiple wireguard server and always use one, which is up and running?
I don't mean a cronjob, which just checks the connection, but a real configuration.

Thank you

You can activate several different wireguard connections simultaneously (I use up to 6 at the same time) but their "AllowedIPs" must not overlap. Your use case (same "AllowedIPs" statement) needs some active components (keeping one connection active, checking for an "offline/disconnected" condition and switching over) and AFAIK cannot be realized via simple configuration.
