General Discussion / Comcast: Issues with their Business router
« on: December 24, 2023, 11:21:56 pm »
Hello
Is anyone else having more than the usual issues with Comcast and its "Business" Router (CBR)?
Initially, I thought the most recent update for Opnsense Business was the problem. I switched to CE with no difference. I believe the issue was exposed when the firewall rebooted.
I tried the USB tethering on my phone and assigned it to WAN with success. If that had not worked I would have tried a spare router with Opnsense CE on it.
This is not a problem for clients, and myself, using Motorola MB8600 modems.
The issues are coming up for those using OpnBE/CE with one of the Comcast Business routers, like the standing model or flat box variations with the corners cut (enjoying the irony). I think all of my clients have the Technicolor brand.
Before leaving on holiday, I was able to fix two clients without having to switch to plain modem. Luckily two are paying for a static IP. On the CBR, I had to switch from Basic Bridge Mode, to it's normal unbridged mode.
I followed an article to at least shut down as many of the functions on their CBR, like WiFi, firewall etc.

This is fine enough for me for my clients with a static IP, however, another affected client has the same OpnBE and CBR combination, but with no static IP. The Opn firewall no longer gets a world IP address, just a local IP on the 10.1.10.0/24 subnet.
Have others been able to get CBR to behave properly with Opnsense when no static IP is available?
Will I live and breathe better if I just switch each of my non static IP clients to a cable modem?
I'm afraid my clients yet unaffected are just sitting on a time bomb. As soon as the equipment has a reason to reboot, or has its power interrupted, boom.
Thoughts, tips, rants, success stories? I lost several hours finding out and figuring out at least something, just before leaving on my trip.
