OpenStack Networking (Neutron)
836f79e7b7
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.
