Public bug reported:

We have installed kilo release

[root@sienna ~]# uname -a
Linux sienna 3.10.0-327.4.5.el7.x86_64 #1 SMP Mon Jan 25 22:07:14 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
[root@sienna ~]# cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"

[root@sienna ~]# openstack --version
openstack 1.0.3
[root@sienna ~]# neutron --version
2.4.0
[root@sienna ~]# nova --version
2.23.0

After installing kilo release, we found that SCTP packets VM were being dropped at the host.
Found that this was a known issue https://bugs.launchpad.net/neutron/+bug/1460741 and downloaded the neutron patch 
neutron 2015.1.2 and applied the same.

After that the SCTP packets from VM were transmitted from the host. But
with the private IP Address (192.168.x.x) without SNAT being performed.

SNAT is being done for UDP packets though.

only SCTP packets are sent out with private IP Addresses.

Please confirm whether this is a known issue and any fix/patch available
for this in Neutron for Kilo release.

Thank you
Balaji Srinivasan
