You have run the BFGMiner on the local machine starting it as a Stratum proxy listening on port 3333 adn then point your AntMiner to it.
Run BFGminer on the same computer as Bitcoin Core with the following configuation, it won't need any further settings altered or configured (it gets the RPC password automatically on launch).
bfgminer --stratum-port=3333
BFGminer will launch, and retrieve the information needed for solo mining.
Now using coinbase address 1PkNBPBGEmvoMFbwRT5ky3XXVNstJnJ4c1, provided by pool 0
Network difficulty changed to 49.4G (353.6P)
Pool 0 http://localhost:8332/#getcbaddr#allblocks alive
Long-polling activated for http://localhost:8332/#getcbaddr#allblocks (getblocktemplate)
Added local bitcoin RPC server on port 8332 as pool 0
Probing for an alive pool
Pool 0 http://localhost:8332/#getcbaddr#allblocks alive
You're now ready to solo mine against Bitcoin Core, you just have to point your antminer at the IP address of the computer running BFGminer, and the miner should show up in the top section of BFGminer with its hashrate showing as "PXY" (stratum proxy). Any blocks will be paid out to the coinbase address shown in BFGminer, which is a new one generated from your wallet.
