If your AT&T U-verse residential gateway is anything like mine (Pace

Yes, mine router is similar
I own and recommend "Networking for System Administrators" by Lucas:

I do too.
And your email helps.
I certainly have a firewall on the computer to go public. And I’m restricting external ssh to one of my remote hosts while I build out my planned set up . I’m just trying to understand the way the ATT router translates to my physical situation.
Conceptually, it seems to me it’s like having two houses: (1) one with the private LAN like most internet connected houses these days and (2) a house like my remote service and hosts at Dedispec where all hosts have one or more public IPs open to ssh from the internet.
On the ATT router I turn on the public subnet and assign one of the static IPs to my desired host.
Eventually I’m going to fancify things with other network hardware, but not for a while.
Thanks, David.
