I have seen this problem in situations where a router isn't dealing
well with window rescaling and out of window packets. I worked around
it by doing this on the machines:

echo 1 > /proc/sys/net/netfilter/nf_conntrack_tcp_be_liberal

If that fixes the issue, to make it persist across reboots, you need
to add it to rc.local.

HTH,
