It works just like a VPN kill switch but requires more configuration. It allows you to whitelist an IP address to torrent from and block any other connections. When enabled, the torrent client will prohibit connections from your real IP address whenever your VPN or proxy connection is disrupted. This effectively blocks the torrent and hides your identity. This feature is called IP Filtering in qBittorrent and can be found in the Options > Connection settings. While it may require some initial setup, enabling IP binding can add a layer of security to your torrenting activities by ensuring your actual IP address remains hidden. It is handy for those frequently switching between VPNs or proxies while torrenting.
