Port isolation?
Port isolation?
Hi,
I have installed an AP behind the TV. Eth1 is connected to the TV's LAN, Eth2 to my NAS, and all other devices in this area are connecting over WiFi.
I can't stream video or use direct IP connections (HTTP/HTTPS), SMB,from the NAS to the TV, or to any device connected to the same AP. However, I am able to do this with any device that is upstream of the EAP655, such as the switch or another AP. It seems that the internal ports are somehow restricted.I haven't set up any VLAN.
In the Omada controller, I have disabled port isolation for the switch profile, and I have checked that all ports are using the default network profile.
Is this an Omada setting issue or a hardware/firmware issue?
How can I solve this without moving the NAS to another location or device port?
Thank you in advance,
N

Thank you for the information.
To summarize:
The issue only occurs between two clients (whether wired or wireless) connected to the EAP655-Wall.
Primarily affects SMB protocol-related services, while other services remain unaffected.
Is this correct? Please feel free to add any other relevant details I may have missed

Dear Vincent,
"To summarize:

"Primarily affects SMB protocol-related services, while other services remain unaffected"
I think this also extends to other things. What I was able to experiment with under the above conditions: SMB doesn’t work at all, I can’t log in. The media server on port 1900 (UPnP) is recognized, browsing content on port 50001 works, but playback on port 50002 does not. The web server doesn’t work either, or at least it loads very slowly and incompletely. I’m not an IT engineer, but it seems to me that wherever TCP protocol is used, the communication speed drops drastically, if it happens inside the device.

Approximately how long does such an inspection take, and when can a response be expected?

This case has been forwarded to our support team for follow-up, and I’ve just remind them to provide you with an update on the progress.
Moving forward, I recommend coordinating with support for further assistance. Apologies for the delay in resolving this. Thanks for your understanding.

So the issue was with the NAS Ethernet settings:
"
...
Specifically, in the packets returned from the NAS to the PC, the destination MAC address was incorrectly populated with the gateway's MAC address. This is abnormal because the PC and NAS are on the same subnet — under normal circumstances, the NAS should:
- First resolve the PC's MAC address via an ARP request
- Then directly use the PC's MAC as the destination address in outbound packets
rather than routing through the gateway.
This suggests a potential misconfiguration of the NAS’s routing policy."
After resetting the NAS Ethernet settings to their default values, it is now working correctly in all locations on the network.
Thanks for the help to figure it out!
