> Adding this feature could be helpful for installation in a restrictive network setup. The "port range" support is already available for some other port config options anyway.
> Right now, it is possible to specify a {{taskmanager.data.port}} and {{taskmanager.data.bind-port}} to be able to support NAT-like setups, although {{taskmanager.data.port}} is not bound to anything itself, so supporting a port range there is not an option according to my understanding.
> Although, supporting a port range only for {{taskmanager.data.bind-port}} can be still helpful for anyone who does not require a NAT capability, because if {{taskmanager.data.bind-port}} is set and {{taskmanager.data.port}} is set to *0*, then the bound port will be used everywhere.
> This change should keep the already possible setups working as is.
