infoblox IPAM with VRA and External VRO

[#1]

Please advise the firewall ports required for infoblox and VRA to communicate. 

Usually customers have VRA and embedded VRO but in our senario customer have VRA and VRO on seperate appliance . 

Do we have to open a port from both i.e. VRA and VRO or only VRA will communicate with infoblox using plugin which is on VRO for IP and DNS details.

When using the plugin, the plugin will connect to NIOS using port 443.

Regards,

Tony
