There are many complaints there.

The problem has been going on since 2014 and documented by many many
people, there are even several internal Comcast tickets that have been
open over the years and then closed.

Unless your running VPNs which is also common in these sectors.

If you don't need a static IP you are fine - as long as you
put the CPE into bridged mode and use your own router.  I did already
say this.

You are also forgetting that most of these installs the ISP supplies
the CPE and the business just uses it out of the box then spends hours
or days of wasted time trying to figure out why things don't work.

Many of the posters to there are pretty pissed by the time they stumble
on to the forum because of this.

Agreed - it shouldn't be - but the reality is that it is.  It would be 
much, much better if the network providers got themselves the hell out 
of the CPE supplying business.

However CPE rentals (at least for Comcast and undoubtedly other network
operators) are big, big bucks.

We live in an imperfect world.
