Hi Antonio,
You can use the node command (wiki:
Click here) to translate the destination IP address and optionally the port.
What is the criteria for selecting a new destination host? Is it a one to one translation mapping the destination IP the client makes a request to, to the external IP address? if you have a large number of destinations to translate to, you could potentially define them in a string datagroup in the format 'source_ip destination_ip' and then use the findclass command (wiki:
Click here) to check the datagroup for the corresponding translation address.
If you want more detailed suggestions, please provide more info on the logic you want to implement.
Thanks,
Aaron
