GTM iRule for DNS_RESPONSE

The DNS_RESPONSE event cannot be used in a GTM iRule. User jacob gives us a pretty cleaver workaround, however, in this article:

 

 

https://devcentral.f5.com/wiki/irules.DNS-Logging-on-GTM.ashx

 

 

Essentially:

 

 

1. Create an LTM iRule with the iRule editor

 

2. In the editor, right click on the iRule and select properties

 

3. Move the listener VS to the "Using this iRule" column

 

 

GTM iRules are applied at the WideIP, and the above applies the LTM iRule at the listener.
