So you got your Antminer S1 pointed it at a local wallet server and watched as every block it found was rejected?
You asked on the forum for help and nobody answered or better still suggested the above.
Follow these steps and you can mine Any Sha256 P2pool Compatible Coin (Still waiting for Peercoin) with an Antminer S1 or setup your own P2pool Pool for Scrypt Mining as long as it has a P2pool Compatible Config.
Revised 11/07/2014

First Pick the coin you wish to mine:
Download and Unpack
https://github.com/Rav3nPL/p2pool-rav
Make sure the coin you wish to mine is listed in the Directory p2pool\networks\
EG.     
Download and Install:
Windows:(Yes only Windows I havent tested Linux though it should be the same)
* Install Python 2.7: http://www.python.org/getit/
* Install Twisted: http://twistedmatrix.com/trac/wiki/Downloads
* Install Zope.Interface: http://pypi.python.org/pypi/zope.interface/3.8.0
* Install python win32 api: http://sourceforge.net/projects/pywin32/files/pywin32/Build%20218/
* Install python win32 api wmi wrapper: https://pypi.python.org/pypi/WMI/#downloads

Download and Install:
Wallet Client for whatever coin you want to mine.

Run and Sync the Wallet Client.
Close the client.
Enter the Directory of the Blockchain/Wallet Dir of the Coin (Windows %AppData% or %Users%Blank%Roaming%)
Create coinname.conf EG. bitcoin.conf
Input

Editing p2pool Configs
Goto where you unpacked https://github.com/Rav3nPL/p2pool-rav
Find the coin you wish to mine.
Edit p2pool\networks\coiname.py

Find

The above numbers is the worker port to connect miners use with the Ip address of the computer running P2pool.
Find
Change to:
Find
Change to:
Save and exit.

Create a Bat in the main p2pool Dir where run_p2pool.py or anywhere if edited properly with the following.
Save.

Now create a shortcut for the wallet client that adds "-server"

Run Your New Shortcut.
LET IT SYNC.
Run your p2pool Bat.
Point your miners at the worker port of your Solo p2pool Node with:
Ip of the Server running p2pool and Worker port.
Address of where you want funds to go MUST NOT BE an exchange address remember this is a p2pool and payment have to mature.
Password "x"

You are now SoloMining/Running your own pool and you can check status by pointing a web browser at the worker port of the p2pool server.
Problems, things I've missed whatever just ask.

Big thanks to seocrow of litecointalk.org for giving me the idea when My Ant S1 kept rejecting blocks found.
Rav3nPL for the multiple coins in individual files now under the networks Directory.
https://www.bitmaintech.com/ for making such a good bit of hardware.

Yep is happening me the same, more or less, when i can connect it starts hashing very unstable and disfunctional until the chains info disapear in Antminer status at miner status page and when i go see the machine it has a red light blinking not to fast.

Also didnt got any reply for Bitmain, thanks god is nice people around here trying to help me out.

             Exactly!

            MEthinks he would be wise to read more...

Same here, I was going to buy 10 but F that at these prices.

my ups is always coming after 6:30pm here. 2 more units expected today as well.
450 at the pool or in web gui?

when did the payment clear?

Thanks!

So all you have to do is uncheck the "Disable DHCP for this interface" checkbox under the DHCP Server? Or does that option create a DHCP server (which would make no sense, but neither does the whole router thing).

I suppose they designed these things so that they could be directly placed on the Internet. But then all you have to protect it is the password.

It's still a weird design choice. I'd be willing to bet that most people are going to put these units behind a router or firewall anyway. Certainly that's what I'm going to do. The only reason to have these units be a router is if they have to route traffic internally.

Maybe the boards themselves are Ethernet nodes on the internal LAN? If so, then I guess that would make some sense that there would be a router between the boards and the outside world. Ethernet for internal communication seems like an odd and expensive connection choice. Unless they wanted the ability to change the product configuration, like have a unit with 4 or 6 boards instead of 2.
