# sys.firewall_rules (Azure SQL Database)
[!INCLUDE[tsql-appliesto-xxxxxx-asdb-xxxx-xxx_md](../../includes/tsql-appliesto-xxxxxx-asdb-xxxx-xxx-md.md)]

  Returns information about the server-level firewall settings associated with your [!INCLUDE[msCoName](../../includes/msconame-md.md)] [!INCLUDE[ssSDSfull](../../includes/sssdsfull-md.md)].  
  
 The `sys.firewall_rules` view contains the following columns:  
  
|Column name|Data type|Description|  
|-----------------|---------------|-----------------|  
|id|**INT**|The identifier of the server-level firewall setting.|  
|name|**NVARCHAR(128)**|The name you chose to describe and distinguish the server-level firewall setting.|  
|start_ip_address|**VARCHAR(50)**|The lowest IP address in the range of the server-level firewall setting. IP addresses equal to or greater than this can attempt to connect to the [!INCLUDE[ssSDS](../../includes/sssds-md.md)] server. The lowest possible IP address is `0.0.0.0`.|  
|end_ip_address|**VARCHAR(50)**|The highest IP address in the range of the server-level firewall setting. IP addresses equal to or less than this can attempt to connect to the [!INCLUDE[ssSDS](../../includes/sssds-md.md)] server. The highest possible IP address is `255.255.255.255`.<br /><br /> Note: Windows Azure connection attempts are allowed when both this field and the **start_ip_address** field equals `0.0.0.0`.|  
|create_date|**DATETIME**|UTC date and time when the server-level firewall setting was created.<br /><br /> Note: UTC is an acronym for Coordinated Universal Time.|  
|modify_date|**DATETIME**|UTC date and time when the server-level firewall setting was last modified.|  
  
## Remarks  
 To remove a database firewall rule, use [sp_delete_firewall_rule &#40;Azure SQL Database&#41;](../../relational-databases/system-stored-procedures/sp-delete-firewall-rule-azure-sql-database.md). To set a firewall rule for a single database, see [sys.database_firewall_rules &#40;Azure SQL Database&#41;](../../relational-databases/system-catalog-views/sys-database-firewall-rules-azure-sql-database.md). To return information about existing firewall rules, query sys.firewall_rules (Azure SQL Database).
