Bitcoin Core JSONRPC only accept requests with 0.0.0.0 in configs

I've lunched a Bitcoin Core server, and trying to connect to it via JSON-RPC.
This is my configuration settings:

server=1  
rpcuser=admin  
rpcpassword=password
rpcport=1234
rpcallowip=94.183.32.151

But all cURL connections to this server via the IP 94.183.32.151 has the same error result as:   

cURL error 7: Failed to connect to 94.183.32.151 port 1234: Connection refused

I tried adding this option too, but it did not solve the problem:

rpcbind:94.183.32.151

Only when I put 0.0.0.0 as a bined RPC IP, Bitcoin core returns true response. I've checked many pages but did not find any other appropriate way to allow some certain IPs to Bitcoind. May you help me please? 

Note: IP, Port number, username and password are changed from real values.
