NETGEAR UTM50-100NAS, UTM5-100NAS manual Viewing Policies

ProSecure Unified Threat Management (UTM) Appliance Reference Manual

For example, a policy that is configured for a single IP address takes precedence over a policy that is configured for a range of addresses. And a policy that applies to a range of IP addresses takes precedence over a policy that is applied to all IP addresses. If two or more IP address ranges are configured, then the smallest address range takes precedence. Host names are treated the same as individual IP addresses.

Network resources are prioritized just like other address ranges. However, the prioritization is based on the individual address or address range, not the entire network resource.

For example, assume the following global policy configuration:

•Policy 1: A Deny rule has been configured to block all services to the IP address range

10.0.0.0– 10.0.0.255.

•Policy 2: A Deny rule has been configured to block FTP access to 10.0.1.2 – 10.0.1.10.

•Policy 3: A Permit rule has been configured to allow FTP access to the predefined network resource with the name FTP Servers. The FTP Servers network resource includes the following addresses: 10.0.0.5 – 10.0.0.20 and the FQDN ftp.company.com, which resolves to

Assuming that no conflicting user or group policies have been configured, if a user would attempt to access:

•an FTP server at 10.0.0.1, the user would be blocked by Policy 1.

•an FTP server at 10.0.1.5, the user would be blocked by Policy 2.

•an FTP server at 10.0.0.10, the user would be granted access by Policy 3. The IP address range 10.0.0.5 - 10.0.0.20 is more specific than the IP address range that is defined in Policy 1.

•an FTP server at ftp.company.com, the user would be granted access by Policy 3. A single host name is more specific than the IP address range that is configured in Policy 2.

Note: The user would not be able to access ftp.company.com using its IP address 10.0.1.3. The UTM’s policy engine does not perform reverse DNS lookups.
