Can you either tell me the required ports the Remote Engine will required or point me to the documentation I had a prospect ask today. Also how configurable will the ports be, for required ports that is? Can the change any ports required in case of conflicts?
No inbound ports will have to be opened. The Remote Engine just calls out to Talend Integration Cloud using HTTPS. Thus, if you don't block outbound communication no port configuration is necessary.
Potentially, you will have to configure an HTTPS Proxy.
