RBR850 rebooting multiple times/day

Then configure AP mode on the RBR. This should stop the rebooting I hoping. 

You can try putting the RBR in the Linksys DMZ as well if you want to keep both in router mode. Not sure if this will stop the reboots if the Linksys is still online. It may. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Thanks again FURRYe38,
I will give these steps a whirl overnight once the network becomes less mission essential for the house. 
By putting the RBR850 into AP mode, i presume you mean moving the DHCP issuance role to the Linksys. If so, then 'OK' and i can see.

On a related note, can you help me conceptually understand why the RBR might have issues that would cause a crash/reset from something on the 'incoming' intenet side of the chain? I had assumed that at worst it would say 'unable to connect to the internet', but to me (as  a s/w & H/W eng) it seems it shouldn't just reset unless a watchdogh or similar out of spec event happens in its code.

Could be anything at this point. My hopes is that the double NAT issue maybe the primary cause. Either using the DMZ on the Linksys for the RBR in router mode or configuring the RBR for AP mode will fix the reboot thing. Have two routers on the same line can cause various problems. And we don't know the status and condition of the Linksys router as well. It's FW up to date? Thats a moderatly older router and going on in age. I personally bailed Linksys about 10 years ago due to them not updating FW and leaving bugs behind on the WRT1900 series. I still have my WRT1900AC I use once in a while as a wireless client. Taking this out of the mix and testing should see results. 

Thanks again FURRYe38 

The Linksys is up to date but ultimately flashed with ExpressVPN code as that is the function. i have switched off just about everythign on teh linksys. BTW - i'm using the 3200 as it has the most horsepower to process the encrypt/decrypt and leave me with at least reasonable up/down bandwidth. Will see if i can verify or resolve the possible NAT conflcts and see if that gets me stable

👍

Any updates on this?

Did you remove the Linksys router or leave it on line and put the RBR in to the Linksys DMZ or Configure AP mode on the RBR with the Linksys in router mode?

Hi FURRYe38,

I had to remove it in the end. I had one of those fun conversations with ExpressVPN's support folks where we explored all conceiveable mitigations to nought. There flashed s/w has limited capability, so no DMZ, no other approaches we could get to, so i have taken the flashed Linksys WRT3200ACM out of the path leaving the ISP gateway CM1000 connected into RBR850. 
Since taking it out, the only unforced reset on the RBR was at 11.15pm, so 12 hours ago. That's a big improvement, but not pristine. 70 devices connected.

At the same time i'm researching VPN options H/W, withing RBR850s openVPN and others to get things back behind a wall. Open to suggestions, but again would need to be a service provider model at teh other end of the pipe (e.g. express or Nord, etc.)
Call me paranoid, but i believe in makign my security better than those who aren't.

best, julian

Thats a shame theres no DMZ. 

Sounds like the reboots are fixed. I hope. 

Ya, you'll find something in regards to VPN. 

Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

Enjoy. 📡

Yay. Glad it's working. Im sure you'll find something.

Enjoy. :smileywink:

And Good Luck.
