This management address space on VLAN 11 is also used as the tunnel source for the Intercloud Fabric Extender,
and therefore the WAN router or firewall should be configured to apply Network Address Translation (NAT) to the
management addresses to achieve a public routable IP address.
In addition, to establish successful communication between the fabric extender and the Intercloud Fabric Switch,
the ports listed in Table 1 should be opened on the firewall. These ports are listed in the Cisco Intercloud Fabric
release notes as well:
