Xfi Advances Security (comcast)

By default, the cable modems from Comcast have Xfi Advanced
security-enabled which is a layer 3 URL blocker.

We can access our URL via that IP fine, but the URL fails.

The fix we're telling users is to 1st allow to unblock the URL in the APP,
then disable the service. Which does fix the issue.

I'm trying to find out why Comcast why they did the block to start with and
how to white list.
