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

Thanks for posting here.
The situation is weird. EAP devices have no default isolation mechanism, to identify the root cause, please provide:
- Network topology diagram
- Screenshots of:
- Device interface
- EAP's ETH port configuration
- IP addresses of the NAS and TV
- Connectivity test:
- If you connect a PC to the NAS's ETH2 port:
- Can it ping the TV's IP?
- Can it ping wireless devices connected to the EAP?
- If you connect a PC to the NAS's ETH2 port:
- Do you set up any ACL configurations?If yes, please send the relatead screenshots.

Hello, thank your help.
Here is the topology:
Controller is running on the NAS what is connected to EAP655s eht2.
3. IP on the same subnet 192.168.1.XXX
4. Yes, I can perform a PING test. It seems that communication is working, but some ports or protocols are very slow. For example, when I try to open a web page on my TV hosted on the NAS at IP:80 or 443, it is extremely slow; even a simple HTML file takes several minutes to load, and only the text appears without any CSS.
The media server is running (on NAS); I can see it and browse the files, but I can’t open them (connected on the same EAP wifi or eth). As soon I am roaming to another AP, or connect to ETH /except EAP EAP655 where the NAS is plugged/ it starts working like a harm.
5. Currently I have no active ACL.
Reverting to the firmware to v1_1.3.1 Build 20240929 doesn't helps.
Thanks,

Thanks for the reply.
Here’s the simplest and most likely solution: Forget and re-adopt the EAP655-wall. If possible, please try this and let us know the results.

Hello,
Unfortunately, it did not help.
Moreover, in the 'forgot' state, when it is supposed to operate in a 'stand-alone' mode and the Omada controller has no effect on it, the LAN-to-LAN connection (TV<>NAS) also does not work. To clarify, it behaves the same way. It can see and browse the media server, but it cannot play media. Opening a webpage takes the same amount of time. Based on this, I still suspect a firmware (FW) issue.
What is your opinion?

Hi @NovaMIT
To clarify, it behaves the same way. It can see and browse the media server, but it cannot play media.
>>Will there be any error message when failed to play the media?
To exclude the TV reason, can you plug another PC, or other kind of wired client into the TV port, and rerun the ping test?

Hello Vincent,
the ping test yesterday worked like this as well.
The EAP655 has 3 ethernet ports. The 1st was for the TV, the 2nd for the NAS, the 3rd for the PC; the ping test ran without any problems. I even tested with larger packet sizes.
The error code leads to a network error on the TV, and it performs self-diagnostics to check the connection. (Tried on TVs LAN and on WIFI as well.)
Meanwhile, on other devices like PC (lan) or mobile (wifi), I try to start videos through VLC, but Samsung’s built-in video player (mobile) does the same.
Although it doesn’t show an error code, it just keeps loading endlessly... (The TV also does this, but after about half a minute it drops and goes into troubleshooting, then shows a network error).
Meanwhile, on the mobile device, the loading doesn’t stop, and if I go to another room where AP roaming happens, the video loads immediately, but when I return, roaming happens again, and the stream is interrupted...
I have installed ipef server on the NAS.
What’s also strange is that if I’m connected to other EAPs, the UDP protocol is slow. But if I’m on the EAP655, the UDP is working while TCP is almost not. Also get errors.
Another EAP

Hi @NovaMIT
Regarding the iperf screenshot, when the server is on the NAS via ETH2, is the client wired or wireless?
Are there any differences between wired and wireless scenarios?
If plug the server into other ETH ports of the EAP655-wall, will the results differ?

Hello, sorry for the delayed answer.
So:
1a.) Client and the server are on the same AP /EAP655W/ connected with wire
1b.) Client and the server are on the same AP /EAP655W/ server on LAN, client on WIFI
2a.) Server still on EAP655W ethernet - Client on ES205GP ethernet (lan-lan)
2b.) Server still on EAP655W ethernet - Client on EAP653 wireles AP:
I have made the same test on ER706W on ethernet and wifi as well, with the same result as not connected directly on EAP655W.
To be sure, that is not on the server (NAS) side, I have replaced the device to the ES205GP switch and the result are the following:
also the SMB is working, I can steam videos on TV from NAS, or on any other device. Evrethings works as is expected.
It works regardless of whether the client connects via cable or Wi-Fi to any network device, including the EAP655-Wall as well.
