rule
SQL Database Server
Windows Azure Platform
By default, Azure blocks all external connections to port 1433.
Enabled in the following ways:
Azure portal
Classic portal: Server level – configure page
New portal: Server settings – firewall – firewall settings blade
# PS Enable Azure connections
PS C:\> New-AzureSqlDatabaseServerFirewallRule `
-ServerName "Contoso" `
-AllowAllAzureServices `
-RuleName "myRule2"
-- PS Allow external IP access to SQL Database
PS C:\> New-AzureSqlDatabaseServerFirewallRule `
-ServerName "Contoso" `
-RuleName "myRule1" `
-StartIpAddress 12.1.1.1 `
-EndIpAddress 12.1.1.2
-- T-SQL Enable Azure connections
sp_set_firewall_rule N'Allow Windows Azure',
'0.0.0.0','0.0.0.0'
-- T-SQL Allow external IP access to SQL Database
sp_set_firewall_rule N'myRule1',

Managing firewall rules through
REST API must be authenticated. For
information, see Authenticating
Service Management Requests.
Server-level rules can be created,
updated, or deleted using REST API
To create or update a server-level
firewall rule, execute the POST
method
To remove an existing server-level
firewall rule, execute the DELETE
method
To list firewall rules, execute the GET
