IP Addresses: Azure SQL Database to SQL Server Instance

[Manoj Chaurasia]

We have a requirement to replicate data from a supplier's Azure SQL database within a VPC to our SQL server instance, which is on-premise. We have the Scribe agent running for the target database server for other database replications we have, and I have been advised that providing the IP address (presumably public IP) of the on-premise SQL server instance to our supplier will suffice in order for the two databases to talk to one another across different private networks.

The question I have, not having had much experience with Scribe myself, is whether a public IP address for our on-prem SQL server is sufficient or whether we will need to provide the supplier some IP addresses to whitelist for Scribe itself
