json_rpc_call solo mining with bitcoin running on Windows 7 for antminer

I setup BitcoinD on a Windows 7 PC. I configured for defaults except user/pw and rpcallowip=192.168.1.0/255.255.255.0. have also tried 192.168.1.* with no luck.

I ultimately want to use an Antminer to connect to it for solo mining but cannot use it for anything other than mining on the same computer on which it is running.

WORKING: using bfgminer with the following command line:
bfgminer-5.0.0-win64bfgminer-5.0.0-win64bfgminer.exe -o 127.0.0.1:8332 -u rpcuser -p rpcpw

NOT WORKING: using bfgminer-5.0.0-win64bfgminer-5.0.0-win64bfgminer.exe -o 192.168.1.123:8332 -u rpcuser -p rpcpw

The only difference is the IP address where 123 is my IP.

Error: “json_rpc_call failed, retry after 30 seconds”

I looked at firewall and it has entries for “Bitcoin Core”

“Netstat -a” output:

0.0.0.0:8332
0.0.0.0:8333
127.0.0.1:8332
192.168.1.123:8333

Antminer says pool is dead.

How do I get another computer or antminer, on my network, to connect for solo mining?

Thanks.
