Connectivity to end point:

License server: should be able to reach outside the cloud

• For BLL based license, you need connectivity from GUI to license server

From GUI: Application should be able to reach the end-point

• Needs Floating IP, one per STC vm (openstack admin should have a block of IP addresses assigned from IT admin,

and inserted into the openstack as a floating IP pool)

Note: Make sure you “allow all” in the security settings, and use the “Hardware Based MAC” from the GUI

• Openstack does not allow MAC address emulation. Please refer to QSG.
