Yes. 

sysctl -w net.ipv4.tcp_default_win_scale=0

is enough. 

(1.2GHz 55C) root@alderaan:/home/trey $ sysctl
net.ipv4.tcp_moderate_rcvbuf
net.ipv4.tcp_moderate_rcvbuf = 1
(1.2GHz 55C) root@alderaan:/home/trey $ sysctl
net.ipv4.tcp_default_win_scale
net.ipv4.tcp_default_win_scale = 0
(1.2GHz 54C) root@alderaan:/home/trey $

With this setting i have not problem, working everything is
fine.
