Use lists in expressions

Expression Builder

To use a list in the Expression Builder:

1. Select is in list or is not in list from the Operator drop-down list.

   

2. Select a list from the Value drop-down list. Depending on your plan, you may be able to select a Managed IP List.

3. To commit your changes and enable the rule, select Deploy. If you are not ready to enable the rule, select Save as Draft.

Expression Editor

To use a list in the Expression Editor, specify the in operator and use $<list_name> to specify the name of the list.

Examples:

• Expression matching requests from IP addresses that are in an IP list named office_network:

  ip.src in $office_network

• Expression matching requests with a source IP address different from IP addresses in the office_network IP list:

  not ip.src in $office_network

• Expression matching requests from IP addresses in the Cloudflare Open Proxies Managed IP List:

  ip.src in $cf.open_proxies
