Empty DNS= and FallbackDNS= in resolved.conf were blocking VPN DNS servers when VPN clients replaced /etc/resolv.conf. Removing these empty values allows systemd-resolved to: - Use DHCP DNS from network interfaces (existing behavior) - Fall back to system defaults when needed - Switch to 'foreign' mode for VPN DNS override Fixes #1509
