Hi.
We found during our internal security testing that the etcd ports 2379 and 2380 are considered low ports and are not allowed for use. Is there a way to change them? I have checked the documentation, but there is no explanation on this. Can someone help me?

No, they are not configurable. These are the IANA assigned port numbers for etcd, see
https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?search=etcd

They are not allowed for use according to what? Are you also not allowed to use the correct ports for other things like HTTP (80) or HTTPS (443)?
