0x40000000000 Comcast Modem

This is just an FYI for anyone out there that gets this error code and (hopefully) has a Comcast cable modem.

I had just gotten a new cable modem from Comcast when I started having connection problems.  On my X1 I would test the internet connection and it would be good, but the multiplayer connection would give the 0x40000000000 error code.

I logged into my modem from my computer and changed the preset firewall setting from Medium to Low and the connection problem cleared up.
