Update custom rules for customers or partners

You may want to adjust your custom rules to increase access by customers or partners.

Potential examples include:

• Removing rate limiting for an API
• Sharing brand assets and marketing materials

If a customer or partner is large enough, you could set up a custom rule based on an autonomous system number (ASN) ↗.

This example uses:

• The ip.src.asnum field to specify the general region.
• The cf.bot_management.score field to ensure partner traffic does not come from bots.

Example custom rule:

• When incoming requests match:

  Field	Operator	Value	Logic
  AS Num	equals	64496	And
  Bot Score	greater than	30

  If you are using the expression editor:
  (ip.src.asnum eq 64496 and cf.bot_management.score gt 30)

• Then take action: Skip:

  • All remaining custom rules

This example custom rule uses:

• The ip.src.asnum field to specify the general region.
• The cf.bot_management.score field to check if the request comes from a human.

If a request meets these criteria, the custom rule will skip User Agent Blocking rules.

• When incoming requests match:

  Field	Operator	Value	Logic
  AS Num	equals	64496	And
  Bot Score	greater than	50

  If you are using the expression editor:
  (ip.src.asnum eq 64496 and cf.bot_management.score gt 50)

• Then take action: Skip:

  • User Agent Blocking

For smaller organizations, you could set up custom rules based on IP addresses.

This example:

• Specifies the source IP address and the host.
• Uses the cf.bot_management.score field to ensure requests are not high-risk traffic.

Example custom rule:

• When incoming requests match:

  Field	Operator	Value	Logic
  IP Source Address	equals	203.0.113.1	And
  Hostname	equals	example.com	And
  Bot Score	greater than	30

  If you are using the expression editor:
  (ip.src eq 203.0.113.1 and http.host eq "example.com" and cf.bot_management.score gt 30)

• Then take action: Skip:

  • All remaining custom rules

This example custom rule specifies the source IP address and the host.

If a request meets these criteria, the custom rule will skip rate limiting rules.

• When incoming requests match:

  Field	Operator	Value	Logic
  IP Source Address	equals	203.0.113.1	And
  Hostname	equals	example.com

  If you are using the expression editor:
  (ip.src eq 203.0.113.1 and http.host eq "example.com")

• Then take action: Skip:

  • All remaining custom rules
