Hello,
well, I cannot at all configure my NGINX which is located in front of 4 production servers (supervision, deployment, antivirus console, etc.).
in fact I would like this nginx server to be in front by a Public IP and dispatch the flows in UDP and TCP to these server according to the called alias as you can see in the attached file. but I do not see at all how to leave only some UDP and TCP port.
Thanks for your help
