We have bugs 8686 and 18293 about SOCKS not working. The problem
AFAICT is the native LD_PRELOAD based socksification libraries (that
override socket functions like connect and accept to use SOCKS
transparently) will break on Wine, since they are based on the concept
of an immutable file descriptor. Wine continually dup()s sockets as
they are shuttled between the app and wineserver, so socket identities
