I think Firewalla just took down my network
I woke up this morning and no computer (of 7) could reach the internet. I'm unsure of the cause, but I think (a) I saw that Firewalla updated itself in the morning and (b) google did a software update as well.
I rebooted everything. Multiple times. And ultimately solved the problem by pulling Firewalla (which had been in router mode) completely out and putting my wifi back as the router (it had been an access point).
I'm really hoping someone will say, "Oh, yeah, the Firewalla update has a bug and a patch will come later today." That would be cool.
In any case, thought I'd mention it. I'd like to put my Firewalla back in because without it, it's like The Omega Man after sundown because the boys (triplets) will know it's open season on game playing again which will make my wife's day a nightmare.
Thanks,
Wallace

There is no update to the Gold for sure. If it happens again, I'd suggest do this (our standard tests)
- ping 1.1.1.1
- ping firewalla IP
- nslookup firewalla.com
This will tell you which is broken.
- ping 1.1.1.1 fails if ISP fail
- ping firewalla IP fails if firewalla is dead
- nslookup firewalla.com fails if the DNS system is dead
There is also another possibility, which may trigger a bug in the Arris, which is timing related. When your ISP is going up and down, which in certain cases the SURFBoard will assign a private IP to firewalla ... (this is a surfboard problem)
In general to fix this problem if you can try this
1. Power off surfboard, wait a bit and power it on, wait until it is fully on, and connected.
2. Power on Firewalla Gold
Above will ensure the surfboard not giving a private IP to firewalla Gold
And if you want, you can open a case by sending an email to help@firewalla.com, we will be happy to look at the logs of the gold

You mentioned the Arris bug. Are there other cable modems that play nicer with Firewalla?
For example, my ISP lists the following as approved. Off the top of your head, do you know if any of these would be better?
- ARRIS SB6141 (my current)
- ARRIS T25
- ARRIS SBG8300
- ARRIS SB8200
- ASUS CMAX6000
- HUMAX HGD310
Thanks,

I too have Xfinity. My Firewalla Gold is set to Router mode. I have the ARRIS Surfboard (16x4) DOCSIS 3.0 Cable Modem, 686 Mbps Max Speed, Certified for Comcast Xfinity, Spectrum, Cox, Cablevision & More (SB6183 White) and I've had a issue in the past where my router (not Firewalla at the time) will lose power for a split second and then the ARRIS modem assign it the .100.x network like @Firewalla said. I bought a UPS to plug my modem and other networking devices in. We loose power briefly a lot where I live so it was always a headache to trouble shoot it, now I don't have to worry.
Until Firewalla can push out the next version with the rate limit, I would suggest looking into the TP-Link EAP245 AP. I have this one for my network. I like it because I can create multiple SSID profiles on it, and set a rate limit for that profile. I have one for a "Guest" network that is limited to 10mbps. Might be good for the kids game devices (Wireless).

Firewalla help got back to me and correctly diagnosed my problem as having entered a url (e.g., http://kid-gaming-site.com) instead of a domain into a domain level rule. It's a known issue and it breaks DNS service. Once I removed the "http://" everything worked fine.
