I'm going to try to coalesce the bits of information from various
emails, but it's still mostly blanks...

Is the BGW210 connected via DSL or the Optical uplink port?

no, (and i hope to have pix in the am), the bgw210770 lan port 1 of 4, connects
to nighthawk internet port of the nighthawk. a nighthawk lan port is used to connect 16 port switch.
all the internal hosts, including the intended web server is plugged into that switch.
 

You have a static IP subnet which should be
108.220.213.120/255.255.255.248 as explained by Richard.

yes, i accept my error in that ip/subnet map.
 

Are you wanting to use multiple addresses?

 att supports only 1 ip exposed ip so i didnt expect an option for more than 1.

Do you want a computer on your network to use one of those public
addresses or are you just trying to port forward from one of those
addresses?

There are a few ways to do those options.
an earlier suggestion was to plug the srvr into the bgw210700
as well as the nighthawk. i've been looking to update my configuration

Where is the web server located in your network?
well, 10.0.0.101 is the internal ip for the web server. 108.220.213.121 is the external ip for that same web server.
 
Would you be willing to move it to a different section?

yes. clearly my approach is not happening; i trust the respondents on this thread; if y'all said stand on my head, i'd try.. ;)
 

Are you using the wifi from both the BGW210 and the Nighthawk?
If so, do they have different SSIDs?

blackhole-nh is the nighthawk, blackhole-att is the bgw210700
 

Do you have the Nighthawk connected to the BGW210 using the WAN port or
a LAN port?

lan port 1.
 
I'm guessing it's the WAN port because you have both a 192.168.x.x
subnet (I assume that's the BGW210 LAN) and a 10.0.x.x subnet (I assume
that's the Nighthawk LAN).  You would be better off connecting the
Nighthawk to the BGW210 using one of the Nighthawk's LAN ports instead,
so you only have one private subnet.  But this also depends on the
answers to the questions about using the multiple public addresses.

 Your suggestion makes sense. i just need to get router access from this configuration.

the current setup allows my firefox session to access both 10.0.0.1 & 192.168.1.254
