We have to sync 2 SQL servers located in different clouds under the different tenants. One in Azure global cloud and another one is in Azure China. I've created a sync group in global cloud, added Chinese server there and got an error: "Cannot open server requested by the login. Client is not allowed to access the server. To enable access, use the SQL Azure Portal or run sp_set_firewall_rule on the master database to create a firewall rule for this IP address or address range."
I know what this error means. I have to add the SQL Data Sync service ip to the allowed firewall rules.
My problem is that I don't know that ip. Could someone suggest, how to get Azure SQL Data Sync service IP which is used to access external resources or is there any other way to solve that?
