Barracuda Web Security Service

IP Blocking and IP Exemption

  • Last updated on

If you are not already in the Barracuda Web Security Service Manager interface, click Barracuda Web Security Service at the top of your Barracuda Cloud Control login screen. The Barracuda Web Security Service Manager interface appears. Click the CONFIGURATION tab.

Specify IP Blocking and IP Exemption settings by selecting the desired Barracuda Web Security Service Connector on the Gateway tab, then selecting the Policy tab.

Configuring IP-based Exemptions

If you want to exempt certain clients or sub-networks from all filtering (including spyware filtering), you can select Add New IP and Port Exemption and specify the source IP address for those clients under IP and Port Exemptions. For example, if you want to exempt an executive’s client machine from all filtering, you can do so using the IP address of the client. Similarly, if you want to exempt certain external devices (such as trusted servers outside the protected network) from all filtering, you can specify the destination IP address and specific port under IP and Port Exemptions. Be sure to Enable your settings before you Save Changes.

Exempted IP addresses will bypass the following block filters:

  • Content filtering
  • IM blocking
  • All types of download blocking

When prompted to sync the Barracuda Web Security Service Connector, click Sync.

Configuring IP-based Blocking

If you want to block certain clients or sub-networks from all access, you can use the Add New IP and Port Blocking and specify the source IP address for those clients under IP and Port Exemptions. For example, if you want to block traffic from a suspicious client machine or email servers or internal web servers, you can do so using the IP address of the client. Similarly, if you want to block certain external devices, you can specify the destination IP address and specific port under IP and Port Exemptions. Note that when the Barracuda Web Security Service Connector is deployed as a forward proxy, IP block/exempt rules based on request destination are not applied. You can use this page to configure clients or targeted servers to bypass scanning or filtering. To avoid accidentally specifying a broader than intended exemption range, be sure to apply the proper subnet mask. Be sure to Enable your settings before you Save Changes.
