There seems to be a terminology issue here too so let me try to use different words.
Generally speaking you can not successfully configure a robot to communicate with a hub where there is a NAT involved. Essentially when the robot connects to the hub, it includes the address that the hub should use to communicate back and because the robot knows nothing about the NAT the address the robot sends to the hub will be unable to be used by the hub.
That's the source of your problem.
To fix this, you have the hub probe. There is no such thing really as a "Hub server". Every hub is just a robot that's also running the hub probe. This is nothing that your customer would even know about really, same way that they'd not really know whether you are running the rsp probe or CDM probe to get disk usage. So one simple fix is just to deploy the hub probe to every robot. That's what we do on more than 7k systems.
If you can't, then why not on the customer's network create a hub (one existing robot + hub probe) that's reachable by all the 25 subnets? Robots have no problem pushing traffic across subnets because it's all TCP/IP traffic and should be routeable on the customer's network. Then that Robot+hub has a tunnel to your tunnel server for all the traffic it collected.

If your client has 24 subnets it sounds like they have a complicated infrastructure.
The best solution will be to set up a hub in each subnet and create a tunnel.

if we try this there are almost 25 subnet to which these robots are located so that would require 25 hub servers in all which will be hard to justify to client
is there any other way to workaround this

this is what a hub is designed for.
put a local hub in the same network as the robot and use a tunnel back to the other hub.
if you have just the one robot make it a hub and create a tunnel.

hi
can anyone suggest the ip that the internet facing robot and the hub should use if the server beyond the firewall is to be used as hub
