Most likely there needs to be something adjusted with the VPN itself and the VPN's tech support is probably better suited at helping you than us. There are some VPN services that do not support BitTorrent traffic (like TunnelBear), so pls always make sure your VPN service allows it.
If you are using any of the VPN services we recommended, see below on how to contact them:
PIA (Private Internet Access)
There shouldn't be anything more to configure within FrostWire itself, but we know some VPNs recommend Port Forwarding (which you can do of course).
Here is some further reading from PIA support we found very useful in understanding how downloading from the BitTorrent network works while using a VPN service.
Torrents are unique in how the tech works, in comparison to FTP or P2P. To download a torrent, you connect to a tracker, which contains a listing within its swarm of seeds and peers. Each seed and peer uses a torrent application to feed the torrent to the swarm. However, approximately 4 in 5 torrent clients block anonymous inbound connections, and thus prevent you from connecting to them to feed from them. There is no way around this, and its entirely dependent on what torrent clients seeds/peers happen to be using within any given tracker. As such, you'd rarely see more than maybe 20-40% of your normal speeds while connected to any anonymous connection in torrents, due to this fact.
With that said, this likely isn't the sole cause of speed or connectivity issues in torrents. This is a very common issue with torrent programs; many require port forwarding to be enabled, in order for them to work correctly. While we can't help you configure your torrent client, we can certainly tell you how to get the port information you need to configure it.
The only way to get a port assigned for use with your torrent client is to use PIA VPN application to connect. You need to right-click on the Private Internet Access application in your system tray, and choose Settings, then click Advanced. Put a check mark in Port Forwarding, save it, and connect to one of the port forwarding-capable servers:
- CA Toronto
- CA Montreal
While connected to one of these gateways, wait approximately 30-60 seconds, then hover over the PIA application's icon in your system tray; you'll get a small tool-tip window come up, which will include a port number. This randomly-assigned port is what you need to enter into your torrent client, to get it to function correctly.
In addition to using port forwarding, you can also try changing the ports the VPN uses to connect; this can help with a variety of issues, including improving overall connection speed:
