I will be setting up my second Synology NAS tomorrow. But what to do about port forwarding?
I need to port forward ports 80, 443, 8443, 5000 and 5001. But those ports are already port forwarded on my first NAS, my DS218+. So what do those of you who have more than one NAS do in regards to port forwarding? I know that each NAS will have it's own local IP address. But I also know they can't have the same ports forwarded.
 
I would like to recommend you to read Security check list in our forum. Download it (PDF) and read carefully each step.

Then Official Syno guide for a port change.

When you have Quickconnect service established in first NAS and you will change the default ports:
- Quickconnect service will find your exact NAS behind your common router.

Advanced recommendations:

In case that the second NAS is a backup of first NAS only, then no need to expose such backup NAS to be visible from internet (strictly advisable), then:
- you don’t need setup port forwarding service in your router for such NAS
- it’s better to disable quickconnect or DDNS services
- Disable all unused File services, except SMB ( your previous post taken into account) Control Panel > File Services
- setup new firewall profile for such policy - your new NAS ports need availability only from your LAN IP addresses or specific LAN addresses (your first NAS, your computer) or entire subnet (each IP addresses from the LAN).
- For the subnet setup - when your LAN is “like” 192.168.1.x, then your entire LAN subnet is 192.168.1.0/24
- I hope, that you have simple router, then no way to disallow IN WAN communication for such IP address. Then no way better security as was proposed above.

Thanks again my friend.
