+<h3><u>Create a Security Group in OpenStack</h3></u>
+In OpenStack, go to Project - Network - Security Groups - Create Security Group with name TFS
+
+Add the following rules:
+
+|Direction  |Ether Type |IP Protocol |Port Range | Remote IP Prefix|
+|-----------|-----------|------------|-----------|-----------------|
+|Ingress	|IPv4	|TCP	|22 (SSH)	|0.0.0.0/0|
+|Ingress	|IPv4	|TCP	|2200	|0.0.0.0/0|

+|Egress	|IPv4	|Any	|Any	|0.0.0.0/0|	
+|Egress	|IPv6	|Any	|Any	|::/0|
+
+__Note__: The IP address will be assigned depending on the network you have configured inside OpenStack. This IP will have to be modified in TeraFlow configuration files which by default use IP 10.0.2.10

 Other virtualization environments might be used; in that case, you will need to adapt these instructions to your particular case. If you want to contribute with details on how you used other hypervisors or platforms, [contact](https://labs.etsi.org/rep/tfs/controller/-/wikis/home#contact) the TFS team through Slack.
