Nighthawk M2 guests are isolated on different bands
Hi there. I've got the Australian version of the M2 (telstra nighthawk m2) with the latest firmware and I've noticed hosts are isolated without any setting to configure this. My use case is that I ha...
No Karl-Man2, they never responded or reached out, and I gave up waiting. I've simply stopped using the joke of a device, and wish I had of known before the return period expired.
No idea how to get this to ping the developers or support staff either.
Ok thanks for letting me know. This is such a weird thing to have inplace an not be able to remove via settings!
I'm going to try and open a support case with Netgear via Telstra and see if i can get an answer as we have multiple devices with this issue. Will let you know how i go.
In our internal testing, this is working as expected. You need to disable firewalls on all the clients so that they are see each other.
Please give it a try and let me know if you still have issues.
Thanks
Hey John,
Thanks for the prompt reply.
Can you confirm what firmware versions you tested this on the M2 and M6 so we can be sure we are on the same level? These are primarily all Telstra Firmware devices at our end.
Also with you regard to a firewall issue, the device we are trying to connect to doesn't have a firewall as its a Brother Multifunction Printer.
This is what best describes the issues we are seeing:
Netgear modem > Brother printer.
Connecting the printer via ethernet to the modem, will allow a laptop to print, only when its connected on the 5ghz network. If the laptop is connected to the 2.4ghz network, it cannot print. It can ping the printer, however accessing the gui or using the brother software for remote access will time out.
Connecting the printer via wifi using the 2.4ghz, will allow a laptop to print, only when connected on the 2.4ghz network. If the laptop is connected to the 5ghz network, it cannot print. It can ping the printer, however accessing the gui or using the brother software for remote access it will time out.
Adjusting the channel, wifi range, dhcp, static ip and any other network related settings does not change this situation.
Can you confirm you have tried these steps? Is there setting we can switch off for client isolation?
Looking forward to your response.
Hi John,
I can assure you this is not a client firewall issue. My day job is in devops, so please have some trust this has been correctly diagnosed and that I'm not just failing to turn off a firewall.
The fault is that at the very least, in this firmware version, on the Telstra branded devices, clients are isolated by interface.
This means
* USB
* Ethernet
* Wifi 2G
* Wifi 5G
are four seperate isolated interfaces, which share a DHCP range, but the kernel of the netgear device is not routing these packets from one interface to the other.
If you read my original post, you'll see that a server is open to connections, and can be reached by a client on the same interface, but as soon as the client is moved to another interface, it cannot open that connection anymore.
I'd really appreciate if you could share with us what devices you used for your testing, and if you actually got a response to work across interfaces, not just on the same interface
Kind regards
If this device is based on a linux distribution (and not something else), I can almost guarantee this is a lack of a `-RELATED` rule in iptables. Connections are established, but replies are not forwarded to the appropriate interface
Hey John,
Did you see my reply to your post last month? Can you confirm this isn't an issue on non-Telstra branded M2 and M5 Nighthawks? As i have only tested on Telstra branded ones.
Thanks.

Let me check with our test team on the test setup. As I understood, we confirmed that PING is working between the 2 interfaces, such as 2 WiFi clients on 2.4G and 5Ghz WiFi can PING each other, etc.
Thanks
