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, Spencer Spencer Coplin 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. Kevin

Try having him change the MAC address of his residential CPE router so the BNG sees it as a "new" device. In my case that resolved connectivity issues after Comcast did some "network maintenance" and broke everything for me. Alternatively, have you tried working this issue from the Business side? You'd probably get more leverage that way.
