So a client of mine uses Comcast Business as their ISP. I drove on-site to configure a SonicWALL. Their modem was in bridge mode with the only option of turning into "pseudo bridge mode" (something like a DMZ). Also, the modem wasn't yet provisioned for their assigned static IP pool. Only Tier 1 answers the phone. If you require Tier 2, a call-back within 24 period IS THE ONLY OPTION! And most of the Tier 1 guys don't know how to do anything other than provision modem, basic reboot troubleshooting, and scheduling a truck roll for physical coax connectivity problems. Or put it another way, I can't schedule in advance (proactively) to setup a business gateway firewall. You have to wait and be reactive, then drive X amount of mile on-site all while the customer is left offline with a business that can't function (IE losing money!!!). But it gets better; Tier 2 will configure the modem and reboot the unit without calling first. Epic fail!
Problem 1: I can't get a modem that will drop down to true bridge mode
Problem 2: Business class support is inharently reactive and not proactive with regards to scheduling downtime.
Problem 3: Tier support of all levels wildly range in competency.
Problem 4: -fill in the blank because I'm sure I missed something here-
