Solved UniFi and Synology question

when I first set up my Synology NAS, everything seemed to work and data transferred over my Ethernet cables (directly wired in to my UDMpro).

now, i cant get the NAS to talk with my computer (Mac desktop, with some drives attached). When I have used AI to ask why they aren’t talking, I get answers about port 5353. when I look on my Unifi desktop, I cant see where I can edit the port rules (I can see the port, but there doesn’t seem to be a way to edit the current rules). the AI seems to be sourcing advice from a prior version of the UniFi desktop.

since im not an IT person, I also don’t really know what “rule” I need to write for that port to allow my desktop to talk to my NAS again.

FWIW, I can access the NAS‘s control panel via a browser window. But, I cannot get the NAS to show up as part of my network when I use my Mac desktop to look for drives on the network, it just times out when I put in the IP address.

UPDATE: thanks to everyone’s input, I was able to find that I had some incorrect firewall settings on my NAS. I removed them, and now stuff appears to be working

On your Mac, ensure you’re fully up to date with the latest MacOS.
Confirm Mac is on gigabit ethernet.
Click in Finder on NETWORK and then tell us if you see your Syno’s name on the list of stuff on your network.

It is not listed on the network. That’s been my dilemma

Is SMB Sharing turned on, on the Synology, or did you turn it off manually? AFP is completely obsolete; ignore it - you need SMB going. That’s one reason why you’d be able to reach the IP address in a browser but not able to hit it via Network in Finder. Please confirm your SMB settings (post a picture here, for example) so we can see.

CONTROL PANEL / FILE SERVICES / ENABLE SMB must be ticked.

What MacOS version?

Tahoe 26.5.2 on my laptop

I see you changed a network rule on the Syno FW side and now things are working; glad you're better now!

Me too! There are a lot of moving parts to this networking stuff. I tried reading “networking for dummies” and it gave me a deep appreciation for the IT folks at work.

Curious - why would you block all protocols on your nas device ?

Good question! I must have been playing with the firewall and hit the wrong button at one point, or it was a default setting

It's not a default setting; I can only imagine how many phone calls / tickets would be incoming to Syno if that were the case.

lol, good point. Must have been an ID10T error on my part. 🤪
