SQL server is replicating to wrong subscriber

I have a publication which is intended to push data to a subscriber over the internet from a remote server to our onsite local subscriber but it ends up on a wrong subscriber.Here is the scenario:

Server A is a remote server hosted in south Dakota ( Publisher)

Server B is a local server ( Virtual Box) subscriber

Server C is also a local server on a virtual box ( subscriber)

Both server B and C listens on port 1433

What I'm trying to do is to replicate a table from server A to server C but replication is pushing the data to server B

Is replication pushing the table to server A because both server B and C listens on port 1433 or Am I missing something else. Any contributions or pointers will be appreciated... Thanks folks
