Trying to connect via 10Gbe from NAS to iMac

[VinceCheong]

Carrying forward from my previous topic (viewtopic.php?f=30&t=166677),
I finally gotten the OWC Thunderbolt Deck Pro, that comes with a 10Gbe Port.

I have a TS-453BT3 ("NAS"), previously connecting my iMac 27" to it via TB3. Now I'm trying for the love of god to figure out how to set up a 10Gbe link directly from my NAS to my OWC Pro Dock that's hooked up to my iMac via TB3. I've been reading thru some threads where people have been asking the same question, and I've sorta followed Bob Zelin's dummy-proof steps of setting up a static IP on both my iMac's OWC TB3 and NAS's at 192.168.10.9 and 192.168.10.10 respectively, with the subnet Mask of 255.255.255.0 (I also tried interchanging them to 255.255.0.0 too), but it kept saying I cannot connect.

Currently I can connect and access directly from my NAS to my iMac via TB3, at 192.168.3.4 and 193.168.3.2 respectively with the subnet mask of 255.255.255.0, it works, but TB3 speeds are now wonky.

Here's my current setup and what I'd like to achieve.
NAS connected to the internet via USB-wifi dongle.
NAS 10Gbe to connect directly my iMac via OWC Pro Dock.
My iMac has wifi connect to the internet.
I have no 10Gbe Switch/Router.

The subnet mask should stay at 255.255.255.0 for both networks. If you set subnet mask to 255.255.0.0 in a network, this network will use all interfaces/adresses starting with 192.168.x.x, so that is exactly what you dont want to do!

Sure, that you use a correct cable?
Is there any link LED switching on when cable is connected to both devices?
If not, error is most likely in physical layer (wrong or broken cable).
I guess at least one device has a LED at the 10G port!?

Hey man, thanks for giving this a go. Everything is on 255.255.255.0 for my TB3, 10gbe and even the USB-Wifi dongle it auto sets to 255.255.255.0 too, but I still get the same error.

I'm on Cat5e but it's like 1-meter long, I doubt that could be giving any hiccups. Both 10gbe ports are lit up. (on the NAS shows solid green, while on my OWC dock it's amber colour which says there's a 10gbe link).

Is there a response to "ping" in 192.168.10.net? From NAS run "ping 192.168.10.9" and from iMac run "ping 192.168.10.10" (assuming that .9 is iMac and .10 is NAS).

one more time Vince -
plug in the OWC thunderbolt 3 to 10G adapter into your iMac (I ASSUME this is a thunderbolt 3 iMac, and not a 2015 or earlier iMac that you have an T2 to T3 adapter on !).
Set a static IP of 192.168.10.9, subnet mask 255.255.255.0. Get rid of the router setting of 192.168.10.1. You do not need this.

On your QNAP TS453BT3, open the Control Panel, and setup a STATIC IP address on the 10G Ethernet port of 192.168.10.10, subnet mask 255.255.255.0. Apply.
Plug in an ethernet cable from the OWC adapter to the QNAP 10G port, and give it about 30 seconds. Does is show that it is connected on the iMac System Preferences> Network menu ?
Does it show that it is connected in the QNAP Control Panel Network menu ? It should be green and say CONNECTED.

SO - if the answer is YES - we can proceed. IF the answer is NO and things are still RED and saying NOT CONNECTED, then you have a bad ethernet cable.
Lets assume the answer is YES, and it shows CONNECTED.

On the Mac, open Terminal. Type this is -
ping 192.168.10.10 (That is the IP address of your QNAP 10G port)
it should show 64 bytes over and over and over again. Does it ?

Lets assume the answer is YES -
now, on the iMac, click on GO> Connect To Server> smb://192.168.10.10
it will ask you for the Name and Password - for now, just enter the admin name and password that you created for the QNAP. I assume that you know this information !
The QNAP will mount on your iMac.

if you were able to PING, and it still will not mount on your computer, go back into the QNAP, and look at your Control Panel in the network area, and look for Microsoft and Apple network services.
These are two separate areas. Is SMB checked ? Is AFP checked ?
Try again - if it fails with smb://192.168.10.10
then try afp://192.168.10.10

I am making an assumption here that you have already created at least ONE shared folder, and have assigned permissions on that folder for the username that you are logging in with - that it has Read and Write permissions ? Because if you have a shared folder, and you have not assigned permissions for you to access that folder in the QNAP, then you will not be connecting or mounting the drive on the QNAP.

Hey Bob, thanks for checking in.

It's the 2019 27" iMac, so yes it's TB3. The OWC TB3 Dock Pro comes with its own 10Gbe port.
Yes I've set a static IP of 192.168.10.9 and 255.255.255.0 on the Mac, and 192.168.10.10 on my NAS, same subnet mask, and got rid of the router setting of 192.168.10.1.

Yes it shows that I'm green and connected on my iMac system preference.

I tried to ping 192.168.10.10, and it shows request timeout. I even tried getting a normal 1gbe router and hook up both my iMac and NAS and let it assign it's own dynamic IP, I can't even access my NAS.

Has this got to do with some virtual switch setting I created back then when I had to get it working with a direct TB3 connection from my iMac to the NAS? Now

Yes, there' a few shared folder created and works flawlessly over BT3, when editing on FCPx.

Is there a response to "ping" in 192.168.10.net? From NAS run "ping 192.168.10.9" and from iMac run "ping 192.168.10.10" (assuming that .9 is iMac and .10 is NAS).

Nope, time out on terminal. Can't ping it. But I can see it's there on LanScan. hmmm.

Any Firewall enabled at NAS (QuFirewall) or Mac?
I am not familiar with any Apple OS, even in 1GB LAN no ping?
Seems to me like a basic network setting which is not set properly.

ACTUALLY, now that you've mentioned this. I think I turned on QuFirewall when I bought my Wifi-USB dongle for my NAS.
How should I make exceptions/filters to allow certain IP addresses to connect.
Let me fiddle around with this when I get back to my Mac.....
