So I activated protonvpn, I set Protonvpn as the network interface in qbittorrent, I turned on port forwarding and entered the port number in qbittorrent, and I believe I should be good to go. I’m just a wee bit nervous because my ISP has already given me a number of warnings and shut my connection down a few times.
Is there anything I’m missing? Is there a way to check if this is working properly?
Yep that’s it. There’s a torrent IP leak test at ipleak.net . No real need for a kill switch, and you can download Quantum off GitHub to set the port automatically whenever it disconnects and reconnects.
In your case I would 100% recommend the kill switch. It shuts the internet off if something happens and given you have multiple warnings…
Just don’t forget about the setting if your internet stops working normally lol. Those posts pop up too and folks forget they have the kill switch on 
Looks like you’ve covered most of the setup! To double-check, you could use an IP leak test to make sure your real IP isn’t exposed while using qBittorrent. There are online tools that can help confirm if everything is secure.
I appreciate the two resources given (the first i’ve now checked out, intend to the second). Could you clarify your comment regarding no kill switch needed? Does the qBittorrent Network interface make the kill switch redundant perhaps? I’d like to utilize ProtonVPNs Split Tunneling feature, and as you probably know, it’s either/or with it and their kill switch. Freeing it up as a viable option, if indeed kill switch is redundant with the qB option utilized.
Once you bind qB and proton together, the kill switch feature is redundant. Binding them together is essentially their own kill switch, and qB will only use the network you paired with it. I haven’t used a kill switch in the past 6 months and haven’t received any letters. My machine runs 24/7. Binding them together is the preferred option over a kill switch since kill switches in Vpns have been shown to be generally unreliable. You can use them together, but like stated before, a bit redundant.
A little late but could you clarify this? My understanding is that if killswitch is turned off and your VPN disconnects, your own ip is then exposed and you’re connected to the internet. Wouldn’t that mean you would also be connected with your actual ip even if qbit is bound to proton?
The reason I ask is because I’m pretty sure that qbit was seeding (on accident) when my vpn and killswitch was off and qbit was bound to proton at the time.
From my understanding, if you bound them together, then no data should be transferred. It’s more secure than the kill switch because it treats proton as it’s only source of Internet and won’t fall back to your Wi-Fi or Ethernet connections. Did you get a letter from your ISP? Id be interested in knowing that.
I didn’t get a letter, though probably because it was seeding only for a few seconds. I’m gonna test it out with ipleak and with a linux torrent.
