Exchange 2013 Store Worker Process in the same DAG uses random ports and consume a lot of bandwith

I discovered that between mailbox servers  2013 in the same DAG , there is a huge traffic between random ports "RPC ports" more specifically related to Store worker process, this process is used to coordinate the activation of database copies on mailbox servers, we have a situation where we need to compress this traffic over WAN, the device can compress only when we specify the port, is there any way to fix these RPC ports, and if we do can this RPC traffic be compressed.
