I don't really have a problem, this post is mainly just for discussion.
I've been a U-verse customer for the past 3 months. Just 2 weeks ago, I learned that AT&T offered static IP blocks with this service.
I purchased the 128 block of IPs with the goal of incorporating them into a simple setup. To define simple, I wanted to only use the default 2wire RG with no further routers. I wanted my personal devices to each have a specific public IP address assigned via DHCP. I wanted a single Linux server to have 60 static public IPs using a single ethernet cable and NIC card assigned as STATIC ips (not DHCP).
I was successful in doing this and have incoming and outgoing connections to those IPs without any change needed on the RG. This setup was done using Debian and does not involve any other router than the RG.
It would take me some effort to write down instructions on how to do this so I figured I would first ask the community if anyone out there is actually interested in this kind of setup and wanted instructions.
If there is an interest, I will be happy to publish directions on this post.

What where the costs associated with getting a block of static IP's?
I am interested in some instructions for your setup.
I too am in the process of setting up a similar network. Only mine is going to involve a wireless bridge for my downstairs because the RG is upstairs.

Standard blocks of IPs are available from AT&T for the following costs:
These are real blocks. IPs will be consecutive and separate blocks cannot be ordered at this time. In other words, you can't order two blocks of 8 to get a block of 16. You must order a block of 16. You can upgrade/downgrade blocks at any time but doing so assigns you completely new IPs.
Please note that because these are real blocks, three addresses are unusable in every block. One is for network, one is for broadcast, and the last usable IP is assigned to the RG. So a block of 8 has 5 usable IPs and a block of 128 has 125 usable IPs.
They will perform RDNS entries for you but they do NOT offer RDNS delegation at this time. They will also unblock port 25 (the only default blocked port that I have found so far) by request.
Do NOT call sales or technical support for RDNS or ordering static IPs. Sales is convinced that IPs require a $149 installation fee + truck roll and technical support doesn't know the difference between forward and reverse DNS.
Call 1-888-722-9337 and dial extension 296
I had to go through hours of phone calls for this number and extension and now it is the only number I call.
This is the AT&T Trial Department. They can order your new IPs within 5 minutes and walk you through how to set it up on your RG without an install fee or truckroll. They will also assist with any RDNS requests/changes.
My instructions would only be confirmed to work on Debian (Lenny) hooked straight into the RG. If you have another router/switch between the server and the RG, the router/switch would have to have the capability to advertise multiple MAC addresses for the WAN port. I can't provide instructions on how to do this since it is not reflective of my network.
To summarize my method, I have used a combination of the /etc/network/interfaces file, a custom if-up.d and if-post-down.d script, and a virtual ethernet driver to get one physical NIC card to advertise multiple MAC addresses. Each NIC card (the physical + all virtual cards) are setup to grab an IP statically (NOT through DHCP) which enables outgoing connections. I then tricked the router into allowing incoming connections (by making it do what it is supposed to be doing but isn't).
Are you still interested in instructions?

No worries on the instructions.
Are the fee's one time or monthly for the blocks?
Thanks for the info!

I believe many things are keeping customers from purchasing IPs at this time. I will list a few of them below:
1) Next to zero advertisement. It seems that the majority of people don't even know U-verse offers static IPs
2) Incorrect information from sales. Sales seems to think that static IPs *require* a truckroll and fee of $149. Big turn off. This is NOT true.
3) Lack of knowledge about static IPs & reverse DNS within Tier I & Tier II technical support. This can keep a customer on the phone for 3 hours+ without any actual information being learned by the customer
4) In addition to #3 above, there is a direct number that can be used to get the trial department for help with reverse DNS and static IPs (WITHOUT a installation fee or truckroll) but this number is not advertised and no one seems to know about it to transfer you there. I only found out because a manager moved me there and someone from that department gave me the number.
5) Inability to easily assign more than one static IP address to a single device. You can do so with the method I mentioned in this post (as I did) but this is not easy to do and may not work in all situations.
plus many many more reasons.
I had to go through a lot of patience, phone calls, trial & error, kernel compiles, OS changes, cable/port switching, etc... in order to get my setup working correctly 100% of the time.

Are you still interested in instructions?
YES I would apprreciate it if you posted or send private the instructions.
I am going to order a block of 8 today.

*** If these instructions are not clear enough, let me know and i'll try to answer any questions you may have ***
This was accomplished on Debian 5.0.2 running the default kernel 2.6.26 using a single physical NIC card connected to the gateway using an ethernet cable.

jsmith, thanks a lot for posting that phone number about RDNS. I too went around and around with lots of nice clueless people before I found your post. I called that number, and despite me having some difficulties with his accent and he with mine, I think we got it done.

Does anyone happen to have instructions on how to do this with Windows? I have a Watchguard firewall bhind the RG and can only use 2 addresses of my 11. Any config advice here?
