Через ваш VPN, або ніяк.

Вбудована функція аварійного вимкнення

Any (the system chooses) is the default. Choose an adapter instead, and GDM sends its connections through that one only. When it disconnects, or the VPN is switched off, nothing goes out another way. Running downloads stop with "… is not connected" and start again by themselves when the adapter is back. The line under the list shows the adapter's address, or that it isn't connected.

Everything GDM opens

It covers downloads and FTP, torrents (peers, trackers, the DHT and the listening port), video pages and image galleries, the DNS you chose, GDM's own downloads and its update check. The command line's get, video-get and gallery-get take --adapter, with the adapter's name, such as Ethernet or wg0, or one of its addresses.

yt-dlp, gallery-dl and ffmpeg can't be held to an adapter themselves. While one is chosen, GDM gives them a proxy of its own on this computer, with a password only they get, and opens their connections through the adapter as it opens its own. Video formats that can't go through a proxy (RTMP, RTSP, MMS, FTP) are refused rather than sent around it.

Як це працює

On Windows, GDM binds the adapter's own address, and Windows then sends those packets only through that adapter. Linux binds the device itself (Linux 5.7 or newer), and macOS binds the interface. An address of a kind the adapter doesn't have, such as IPv6 on a VPN that has only IPv4, is refused, not sent around it.

The system's DNS looks names up its own way, and Windows may ask over every adapter. To keep the names inside the VPN as well, choose a DNS in Options → Connection → DNS: GDM then asks it through the adapter. See DNS and proxies.

Що ще не підтримується

ftps://адреси (неявний TLS) не запускаються, поки вибрано адаптер; ftp:// з TLS працює нормально. З'єднання з цим комп'ютером не прив'язуються, тому проксі, що працює на цьому комп'ютері, вирішує, куди йдуть ваші завантаження звідти. У macOS VPN, який перепідключається, може повернутися як новий інтерфейс (utun5 замість utun4): виберіть його знову.
