I had ran nmap against from the private side and saw it had a service listening on port 80, so I pointed my browser at it and a webpage came up. I looked like it was for setting up the "Wireless" because that is what the menu button said, so I initially didn't investigate it until after I had sent my previous message. Turns out it gives you full access to setting up port forwarding, DMZ, firewall, etc. So it looks like I can use DMZ mode an be in business. Regards, Steve PS Brighthouse/Spectrum in my area lets you BYOD from a pretty large list they have certified on their network.
