Swaminathan Vasudevan 30f35e08f9 Packets getting lost during SNAT with too many connections
We have a problem with SNAT with too many connections using the
same source and destination on the network nodes.

In addition we can see in the conntrack table that the who
"instert_failed" increases.

This might be a generic problem with conntrack and linux.
We suspect that we encounter the following "limitation / bug"
in the kernel.

There seems to be a workaround to alleviate this behavior by
setting the -random-fully flag in iptables for port consumption.

This patch fixes the problem by adding the --random-fully to
the SNAT rules.
