Spectrum Internet and MX67

[BusterDude]

Hello all.  Has anyone ever had an issue with a Meraki connecting directly off of a Spectrum cable modem?  Was working with a new user who also has another carrier at their home.  The Meraki connects just fine on the other carrier, but will not connect to the Meraki cloud over the Spectrum cable modem.  Wondering if there's a special setting on these modems that someone is aware of that we need to set to get this to work.

Thanks.

Is the modem in bridge mode? Possible firewall enabled on it with non default config? The modem is working for other devices? Those are things I'd check. I'm used to them screwing up the static IPs, but beyond I can't recall anything specific beyond billing issues shutting of the account.

Not sure how the modem is set currently.  It's at the user's home and they run their TVs/Laptops/other personal devices over this modem just fine.  I was able to walk the user through turning off the firewall temporarily but this did not work either.

If they have all those devices, the modem won't be in bridge mode, it'll be in routed mode, but (non Spectrum specific) that shouldn't be a problem.

I've had this happen once with Spectrum, we had a random routing issue, we had to provide them with traceroutes to show that it was failing to reach the other end.

You can required connections for the cloud if you go to Help->Firewall Info and check the traceroutes that way

Thanks for the info.  I'll check into this.
