> This is very cool. But my setup is different. My DNS server sits physically in-line behind a GTM. The DNS IP address is being advertised from the server via OSPF. In that instance, would I be able to apply the iRule to the WideIP?

 

 

< Sure thing, only it needs to be applied to the wideIP's virtual server, not the wideIP itself. The GTM setup is here: http://devcentral.f5.com/wiki/iRules.DNS_Blackhole.ashx

 

 

> I did look for that but i don't have a virtual servers section under "local traffic" on my GTM. I am running 10.2, maybe that is why? I do realize I'll need to upgrade for this to work, by the way :)

 

 

< With GTM license these abilities will be in place when you upgrade. I will update the article to note that at a minimum the DNS Services module is required for LTM-only solution to work.
