WiFi client isolation issue?

[Mordac]

I am having all kinds of trouble reconfiguring WiFi connected devices that require setup through a cell phone.  I believe I have discovered the problem, which is that there seems to be client isolation set within the same frequency's network.  It's possible I'm blind, but I don't see a setting for this anywhere.  I have verified this by segregating the WiFi networks and pinging the devices in question from my phone (IPs pulled from Device Manager).  From 2.4 GHz to 2.4 GHz, no traffic is passed but when I connect the phone to 5 GHz it is suddenly able to ping and device setup completes.  I can't ping in the other direction, as these other devices are smart home devices and have no console.  I have further tested this by running a constant ping from my phone to a laptop and switching between the two networks.  As soon as the laptop connects to the other network, pings start coming back.  Networks in question are the secured networks, not the guest networks.  Where can this be turned off?

If you disable SmartBOOST fully does it work then? There isn't an option for that but I can request it

[Mordac]

I did not see an on/off toggle for SmartBoost, but I removed all items from the list and the behavior is the same.

[Netduma Fraser]

Click the  icon top right of the page and then go to settings and you can disable it fully from there

[Mordac]

Still does not work when disabled.

You need to separate the networks like a guest network that should isolate clients from all other clients.

so for example I have 4 networks and 2 isolated networks, one for guests on a voucher time setting and another for some equipment attached. It’s however not a Duma router.

if this feature is not available perhaps worth thinking of adding it as a feature at some point.

I don't want client isolation but it is doing it anyway.

[Newfie]

They should be able to see each other, sounds like a bug or internal setting error. 

 

[Mordac]

Not on the same WiFi band.

[Newfie]

Have you separated 2.4 and 5Ghz and given them individual names?

[Mordac]

Yes, when clients are on the same frequency/network no traffic is passed.

[Newfie]

Clients should be able to see each other, unfortunately I don’t have an R3 to test this out but they really should be able to communicate with each other without any need of a work around.

Hello Mordac, I am also a R3 user and I am experiencing a similar issue, already reported here https://forum.netduma.com/topic/52907-unable-to-connect-to-the-local-wi-fi-server/

I was browsing the forum to see if anyone has experienced the same bug and I saw your post. Please take a look, I think it’s the same problem.

In short, my Mac can’t see my iPad, they are both connected to Wi-Fi 5GHz, but it’s possible to see my NAS, which is hard wired to the router.

Netduma team, sorry to bother you before Christmas, but please help, it’s a serious issue.

Update: I tested with an old phone with only 2.4GHz Wi-Fi support. It worked, the phone can see my iPad on 5GHz band. I can confirm that my issue was also caused by this band isolation issue.

Dear Netduma Team, do you have any updates on this issue? Thanks in advance.

I wrote steps to reproduce in my post.

[Netduma Fraser]

Thank you @cedric108 it does look like the same issue as the OP, thank you for the reproducible steps, I will pass it onto the team to look at ASAP!

[Mordac]

I installed 4.0.20, and this behavior still occurs (which I expected since it wasn't in the patch notes).  Just wanted to keep you updated.

Thanks! We've identified the issue so the team will get it resolved after the holiday break

[Mordac]

.147 seems to have fixed this issue.

[Netduma Fraser]

That's great to hear, thanks for confirming!
