Thank you, he has the xfinity provided router/modem, so no cpe router to make a change on. I don't think we can change 
it's mac address. Good thought on pursuing it through the business side and I'll proceed with that.

Thank you,

We’re facing the same issue at my current job. We have many users at home who are unable to access sites in our 
datacenter. We found that if the user disables the "XFi Advanced Security feature" on their Comcast provided router, 
they can reach our sites again. We’ve been trying to work with Comcast to see if there is any way to work around this 
and find out why it suddenly decided to block our content, but don’t have a good solution yet. Might be worth having 
your user try to disable that feature to see if it helps.
