A problem with my replication system as occured.

I have a working SQL server that can do replication trough internet, everyting works

The problem is when I try to import large amount of data (10000 rows) to my database on the SQL server

the subscriber on my client don't get the new inserted rows. That will say imported data is not being replicated.

only rows that i have manually inserted will be replicated.

I used the import wizard that came with SQL server.

Is there a solution to this problem?
