Re: XR500 DHCP issue

That doesn't really make much sense, the devices are requesting a public IP address or a LAN address from the modem?

Re: XR500 DHCP issue

A public IP address from the ISP is what they are telling me. I have fiber internet with an ONT with one Ethernet port plugged into the router’s Internet port. My PS4 and Apple TV are hardwired into the router. Also a S8000 Nighthawk switch is hardwired for which the Hue Hub is wired to. These devices are showing up in my ISP’s routing table as wanting a public IP. I reboot my router and they clear the extra devices from the table and all is well for about 8 hours and then it all happens again. Back in December it was occurring and happened to notice my NAT was Open so I set it to Secure. This seemed to resolve the issue until now.

Re: XR500 DHCP issue

From my ISP in December.

 

Thanks for calling in just now about your connection dropping. After digging around some, we're of the mind that this behaviour is due to some unexpected DHCP requests that the router is forwarding to us instead of handling internally. You noted that this started on the 26th so I rooted around some historical logs and I do see a difference starting then. The question boils down to why some other devices besides the netgear are popping up on our end. We should basically only ever be talking to the router directly. 

There's a lot of data in the logs, but cutting out some here's an example from the 25th. The 24th looks the same, and these are all the requests in the 24 hour period: redacted due to IP address

 

******

But on the 26th some other devices start popping up. This behaviour continues until today:

Re: XR500 DHCP issue

That's very odd. I've never seen this problem before. Just to double check - the switch is connected into the XR500 right?

 

At this point, I would reboot your modem then factory reset your XR500 and see if that solves the problem. Perhaps there is some DMZ or port forwarding rule that is causing problems.

Re: XR500 DHCP issue

Correct, the switch is plugged into one of the 4 Ethernet ports. I do not have any port forwarding or DMZ configured.

Re: XR500 DHCP issue

What Firmware is currently loaded?
What is the Mfr and model# of the ISP ONT the NG router is connected too?

Re: XR500 DHCP issue

When the issue occurs do you notice that you're unable to connect to the internet or the interface with wired or wireless devices?

Re: XR500 DHCP issue

Wired and wireless devices are unable to connect to the Internet. I am still able to access the NetDuma interface with both wired and wireless devices during this time.

When this happens, on one of the devices, can you find out what IP it is receiving please?

Re: XR500 DHCP issue

Ok, just checking for NAT issues here. Your fine here. 

SHouldn't be having any issues with DHCP on the XR router.

Re: XR500 DHCP issue

Goonies, can you tell what the IP address shows on the actual device network settings when the issue occurs?

Yes it does sound like that, just trying to be sure

Re: XR500 DHCP issue

It has occurred again. Looking at the XR500 IP address it is the one assigned by my ISP. The devices that are requesting an IP and getting forwarded to my ISP (PS4, Apple TV, etc) are showing a local IP of 192.168.*.* so nothing seems out of the ordinary when looking in the DumaOS dashboard.

Re: XR500 DHCP issue

@Boga the forum post you referenced in the NetDuma community sounds the same except mine occurs without a reboot and just happens after a certain amount of time lapses

Re: XR500 DHCP issue

This may have been suggested before, but have you tried installing this hotfix firmware?

Re: XR500 DHCP issue

It has been over a month since I have downgraded to V2.3.2.22 and everything is working it should. Hopefully this not only helps others with the same issue but it will be fixed in an upcoming patch.
