socks4 or 5 proxying - does qbitorrent send the piece data through the proxy?

[dandroid]

I would like to direct all traffic made by qbitorrent through a socks4v or socks5 proxy (including the piece packets)

When using a socksv4 or socks5 proxy for qbitorrent, does it send the piece packets through the proxy or just control messages?

I am currently running my own proxy based on the python twisted socksv4 proxy and cannot see any large packets going through, making me think that qbittorrent does not actually use the proxy for all traffic. Am I missing anything?

My current settings are to use  a proxy running on localhost at port 9999. the qbittorrent client seems to be operating normally.

EDIT: it seems as though qbittorrent doesn't use my proxy at all. it simply ignores all socks proxy settings and just runs normally. Is this a known bug?

The bittorrent protocol actually downloads the pieces in 16kB blocks of data.
