Editing the Blocklist

Add and remove IP addresses from the blocklist

Add IP addresses to the blocklist to block known-bad IPs from accessing the backend of your application. It’s also possible to add User-Agents to the blocklist by defining a pattern to match. You should add known-good IP addresses to the allowlist to allow them to access your application. For more information on adding IP addresses to the allowlist, see Editing the Allowlist.

Add an address set to the blocklist

Click Blocklist on the menu.

Webscale blacklist page in the control panel

Under the Blocklist Address Set section, click the drop-down menu and select an address set.

Add an IP Address

Click Blocklist on the menu.

Under Blocklist by IP address, enter the IP addresses or ranges separated by commas or spaces. In the Description text area, enter a description so you can remember why you created this entry. Next to this field is a slider to select the duration of the blacklist. To create a blacklist entry that never expires, leave it as-is. When finished, click the Done button to add the entry.

The Entries section is below the Blocklist by IP address section. It lists currently blocklisted addresses, which contain the following information:

  • IP address
  • Label
  • Expiration date
  • Created date
  • Creator

There are also two buttons: an edit button, and an X button that removes the IP address.

Add an IP address from the Traffic Viewer

You can add IP addresses to the blocklist from Traffic Viewer. In the Traffic Viewer logs viewer, hover over the Request Address, Peer Address, Server Address or Proxy Address column, then click the small arrow that appears to display the popup menu. You can also right-click on any of the columns to bring up the pop-up menu. Once the menu is displayed, you can select Add to blocklist “Blacklist”.

Add an IP address from the CSP Logs Viewer

You can add IP addresses to the blocklist from the CSP Logs Viewer. While in the CSP Logs Viewer, hover over the Request Address or Peer Address column, then click the small arrow that appears to display the pop-up menu. You can also right-click on any of the columns to bring up the pop-up menu. Once the menu is displayed, you can select Add to blocklist “Blacklist”.

Add an IP address from the Pageviews Logs Viewer

You can add IP addresses to the blocklist from the Pageviews Logs Viewer. While in the Pageviews Logs Viewer, hover over the Request Address or Peer Address column, then click the small arrow that appears to display the pop-up menu. You can also right-click on any of the columns to bring up the pop-up menu. Once the menu is displayed, you can select Add to blocklist “Blacklist”.

When you add an entry to the blocklist from either the Traffic Viewer, CSP Logs Viewer, or Pageviews Logs Viewer, the entry will never expire. Note that the Add to blocklist “Blacklist” item will only appear if the blocklist is using either a Manual address set or a Combined address set that includes a manual set. If the option does not appear and you believe it should, you may have to reload the page.
