LTM policy based on client source IP

Hi everyone.

 

We are in the process of reviewing our iRules to see if there are any we can simplify or replace with configuration as we move up to newer versions of 11.x.

 

Does anyone know if there is a way to build a LTM policy that matches on the IP address of the client ? I would have thought it would be obvious but I cannot spot it anywhere.

 

We have certain clients we apply particular redirects to - some hardcoded in iRules and others listed in data groups. Would love to be able to build a policy that matches the client IP to an IP is an iRule data group.

 

If not, I'll just stick with my current iRule.

 

Thanks ! Mark.
