Connection to external DB between Own DBs

You should look at replication rather than connection to external DB. You can configure replication to synchronize objects from the master vault to as many other vaults as needed. Only prerequisite is that the properties in the object type on the master vault also exist in all other vaults and have the same alias.

What if I dont want to store information on a server that has access to the internet? Are there any options to access information on my internal server from the external one only upon request?

If you give us more information about what type of prolems you have on "connection to external DB" part maybe we can help on that end.
