Multi-db, how to split into remote server

Using multi-db 3.2.4 to split db into different db's under two different server.
eg:
first server: 127.0.0.1(local server contain wordpress multiste)
second server: 127.0.0.2 (remote server to split db)

first server contain my wordpress default db and site contents. Split db in First server within that server works fine. But i try to use both servers to split it gets error:
"Houston, we have a problem!
Looks like you need to create your new db's! If you're lucky, this link still works - click me
Database Error:"

Settings done:
db-config.php
add_db_server('global', 'dc1', 1, 1,'127.0.0.2','127.0.0.1', 'db_global', 'sam', '123');

add_db_server('0', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_0', 'sam', '123');
add_db_server('1', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_1', 'sam', '123');
add_db_server('2', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_2', 'sam', '123');
add_db_server('3', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_3', 'sam', '123');
add_db_server('4', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_4', 'sam', '123');
add_db_server('5', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_5', 'sam', '123');
add_db_server('6', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_6', 'sam', '123');
add_db_server('7', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_7', 'sam', '123');
add_db_server('8', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_8', 'sam', '123');
add_db_server('9', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_9', 'sam', '123');
add_db_server('a', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_a', 'sam', '123');
add_db_server('b', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_b', 'sam', '123');
add_db_server('c', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_c', 'sam', '123');
add_db_server('d', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_d', 'sam', '123');
add_db_server('e', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_e', 'sam', '123');
add_db_server('f', 'dc1', 1, 1,'1270.0.2','127.0.0.1', 'db_f', 'sam', '123');

move-blogs.php

$dbname = "db";
$blog_table_prefix = 'wp_';
$newdb_prefix = 'db_'
$dbhost = '127.0.0.1';
$dbuname = 'sam';
$dbpass = '123';

Is there any mistake? otherwise give me a solution to split db into both remote server and local server too.
