No, setting /proc/sys/net/ipv4/tcp_window_scaling to 0 did the trick. I
echo "net.ipv4.tcp_window_scaling = 0" >> /etc/sysctl.conf
to make it stick.
Here's the thing that bothers me. With earlier 2.6.x kernels (2.6.9 on
2.6.12 built on fc6 box), the problem isn't there. I've verified that
tcp_window_scaling is enabled there. Same firewall, etc.
So, what changed?
