Getting to Apache2 server via AT&T's NVG589

I have a tumbleweed server running Apache2. The software I ensure is up to date regularly. The server running Apache2 now has a static IP address, which is 192.168.1.1. It did have a static IP address assigned to me by AT&T and AT&T configured the router, an NVG589, so that Apache2 would be accessible from the Internet. That did work but it made a mess of things when other machines on the LAN tried to access this one machine. So I want this machine back to being 192.168.1.1. I configured the router to use NAT/GAMING and that port 80 traffic would go to the 192.168.1.1 machine.

In doing a port scan from the outside I receive the message that port 80 is responding. However, with my tablet being outside the network and trying to go to my domain name that is associated with my static IP address, I receive the message unable to connect from Firefox. I have looked at the logs for Apache2 and for the domains, but nothing is there.

Thank you for your help!

Never mind. I found out I can have an alternate address which seems to work.
