YourAmigo lookup and forward irule

This is a common misconception (I think that's the right word!) There are effectively two routing tables on a BIG-IP, one for the Linux Host Management System (HMS) and one for TMM/LTM. The HMS route(s) can only be viewed at the CLI and generally use eth0; these routes are only used for management traffic such as SNMP sourced from the device, not for traffic handled by LTM. The LTM routes as seen in the GUI or at the CLI with [tmsh] show net route command are the routes used when handling traffic via a VS, NAT or SNAT.

 

 

Anyway, this may all be moot, according to this article: https://devcentral.f5.com/wiki/iRules.NAME__lookup.ashx - "If you do not include the @{IP/Virtual Name} argument, local bind will be the target of the query. If your local bind is not set up to query recursively, and is not authoritative for the domain in question, you will receive no response"

 

 

Is that what you are seeing, no response?
