Have an AT&T Uverse Business grade account.

On an AT&T Uverse 2Wire 3801HGV Gateway, Is there way to port forward any of the  5 AT&T assigned public static ip addresses to an existing static private ip address - such as 192.168.1.10?

The private ip address 192.168.1.10 cannot be changed and has to remain static.

With those uverse modems the best way to accomplish this is to put the modem in 'bridge mode' and then have your own router sit behind it that can do 1 to 1 NAT of your public IP to your private IP.

I was wanting to do that like I've done on the traditional AT&T DSL business accounts but AT&T says this Uverse unit cannot be bridged.  I don't know it if is a technical reason or some AT&T policy reason.  AT&T won't give me a specific reason why it can't be bridged, they just told me it can't.  

There is a port forwarding feature in the unit to port forward to a private ip address but when executed, it does not use any of the assigned static public ip addresses, instead it uses a dynamic public ip address completely different from the range of assigned static public ip's .

From within its firewall I found a place where you can port forward one of the assigned static public ip addresses to another one of the assigned static public ip addresses but it won't allow you to select an existing static private ip address.

I had the same issue with uverse myself. I didnt want to post all the crazy things they told me here since it will be a long story. To cut it short, that modem can be bridged and I was able to get them to do it. The key is not to use the word 'bridged' I think its on their tech support cheat sheet to run for the hills anytime a customer mentions it.

I was able to get a tech to email me the instructions. I hope this helps. I know some 3801 have different firmware so the steps may be slightly different

Remote into GUI interface using http://192.168.1.254
 
*Select Settings tab
*Select Broadband Tab
*Select Link Configuration Tab
 
In the Supplementary Network Section is where Static Range needs to be configured
 
Add Additional Network
Enable: Please put a check mark
Router Address: 99.121.x.x
Subnet Mask: 255.255.255.248
Auto Firewall Open: Please put a check mark
***SAVE CHANGES***
REBOOT
 
You can then configure your first available public IP on your own equipment.
