I'm not sure, that I understand you correctly. Can you be more specific
about your setup?

If your node resides at your home network, your provider sees only the
traffic, which goes out and in, passing your internet-link router. Your
provider sees your router's MAC and sets your external IP-address, so
he knows both. As long you haven't set any port forwarding (allowing
inbound connections on your router), nobody from the outside can see, if
any ports are open within your local network.

Only if your router is compromised, either by remote controlled
auto-updating (your provider) or by using an exploit (a random
attacker), it is possible to enable remote login for watching your local
network traffic at the end.
