title: Can I configure mysql Replication on port 13306 and normal database operation on 3306?
body: <p>I know Mysql Replication works on 3306, but what I am trying to  understand is,</p>
  
  <p>is there any way i can keep
  a) 3306 for normal Mysql Operation and have 13306 for Replication purpose only ?</p>
  
  <p>I have a requirment, where We need to setup mysql Repliation  over Dynamic IP which means our mysql server will be open to public, so we want to protect our database, and want to open minimum port which only for replication ( we will setup SSL replication)</p>
  
  <p>b) if this is not possible , what other option do I have where we can only apply only changes from master to slave or master to master  ? </p>
  
  <p>can this be done ?  thanks for sharing any lights or references on this.
  Thanks</p>
