Symptoms

An LTM policy using a rule that attempts to match based on a list of IP addresses may fail if more than one IP address is used.

Impact

The action configured with the match may not be taken.

Conditions

LTM policy rule with a 'tcp match address' statement that attempts to match against more than one IP address.

Workaround

Use one of the following workarounds: - Use a subnet instead of single IP addresses. - Use a datagroup with the list of IP addresses to match. * Datagroup option available beginning in v13.0.0.

Fix Information

The BIG-IP system now correctly matches several IP addresses in LTM policies.
