I'm still not having any luck.
You have rpcallowip listed twice in your conf. delete the 127.0.0.1 line -- and allow: 192.168.1.* That should let anything on your network mine, even the local machine.
You can put so many rpcallowip in the config like you wish. 127.0.0.1 only says that the rpc can connect aswell from localhost.
Mining Direct to the Wallet with Antminer 180GH/s will not work as the wallet can not send the work fast enough to the miner.

Saw to late in your Picture that you put rpcallowip=192.168.1.2 which means only exact this ip can connect to your wallet.Yep, that seemed to be the problem, 192.168.1.* was indeed the trick. I'm getting mining stats out of my Antminer now, however I guess I wont be completely sure its working for me until I hit a block.
And yes it does, last time I didn't use the new node, I broke your server

The stats are a bit off since I have been trying to solo mine with it, but this is pretty similar to the share count I'm getting with your pool

Ouch, that's not a pretty picture.. Thanks for checking the IP. Now I'm wondering whether other people are experiencing the same issues with accepted shares rate; the average rate of dead shares on the new node is 10%, which is high but doesn't begin to explain 75% rejected.. I suppose you're familiar enough with P2Pool mining that the tips described on
https://en.bitcoin.it/wiki/P2Pool#Miners won't be of any help :/? I'll dig around in the logs in case I missed something. Could you tell me which address you're using?
I'm using Gf8ECtajSbeQfwweVDQrPvU4aRv4XcfYZq
*edit* I remember noticing that my getworks were incredibly low.
