Perhaps look into Network Address Translation (NAT) and Port Address Translation (PAT). Also, may want to consider proxies and TOR browser.
None of those things has anything to do with what he is asking about. Changing ports does not mask traffic, and TOR only encrypts its own sessions.
You make good points, not sure if OP was trying to mask traffic or disguise real access to the pool. Just putting out additional ideas that can be looked into further or rejected as things are trying to be figured out, if not already.
