Yes. If you want to add another HDD, the best way is to setup another node using different ports and generate a new unique identity, signed with a new authorization token, as described in the guide. Any DDNS service will not help to forward ports, it can help only with dynamic public IP. If your public IP from there: [Open Port Check Tool - Test Port Forwarding on Your Router](https://www.yougetsignal.com/tools/open-ports/) doesn’t match the WAN IP on your router - the port forwarding will not work and DDNS will not help. In such case you have few options: > [@Noob here! My node shows offline all the time.
