Both restricted EPoSe RPC and wallet RPC commonly use `8198`, but they are different processes. They cannot share one host port. The `18082` value above is an example override, not a protocol default.

* Prefer loopback binds for unrestricted daemon RPC, wallet RPC and ZMQ.
* Use firewall rules in addition to bind addresses. Account for Docker-published host ports.
* Configure RPC credentials in a protected file or service environment, not shell history.
* Repeated `--seed-node`, `--add-priority-node` and `--epose-v2-discovery-endpoint` options are lists, not allowlists.
* Never expose wallet RPC because an EPoSe guide says to open `8198`.

See [Daemon JSON-RPC](/apis/daemon-json-rpc.md) for route-level restricted behavior.
