PSA: Your torrent client (even with a VPN) could be leaking your IP

So I was browsing the internet one night and I suddenly get forcibly redirected to a page stating my ISP has received notices of DMCA violations. Except I regularly use a VPN... At first I thought it was a phishing attempt and called up my ISP to confirm it. Yep, it was valid. Next came the question of how in the fuck the RIAA lawyers got a hold of my IP. I did the usual IP leak checks. Nope. No problems there whatsoever. I then did a torrent leak check with ipleak.net. And there it is! My true IP right there along with the VPN IP.



I don't even want to know how long this has been going on for. I should probably thank the RIAA lawyers for the free security bulletin, but even so... What the hell is causing the fucking leak??? I tried reinstalling both the VPN and the torrent client completely from scratch. Nope. Still leaking. I then went into my MX Linux dual boot to test a theory. No leak there though. All clean. Ok, so whatever this is, it's a Windows problem of some kind. I then did a bit of searching and then quickly found out that... WHOOPSY, you need to set the torrent client to explicitly use the TAP adapter connection. And right after I set that, no more leaks...

Fucking hell...

TL;DR then. Be warned if you use a torrent client and a VPN as you need to set the torrent client to EXPLICITLY use the Windows TAP adapter connection so it doesn't accidentally bypass the VPN.

IPLeaks.net shows the same VPN adress for me. I don't have Tap on my comp. Maybe it depends on your torrent program/setup and your VPN program or company.

This is probably why Linux doesn't leak either. There's no separate connection to leak from.
