GTM IRule

Question

I would like some help to create an IRule. 
&nbsp; We have two pools external pool and internal pool. At the wip we need to setup an IRULE to basically force any user coming from a particular subnet(s) to go to the internal pool, else go to the external pool, from what I know the syntax between an LTM irule and GTM irule is quite different, as we have this setup on our ltm infrastructure, but that ltm irule was not able to save as a gtm irule, the gtm would not like it.

Hi Wish, 
&nbsp;     The description you provided sounded very much like LTM irule.    GTM's iRule typically surround DNS resolution.  The following link will take you to the wiki entry for GTM irules.

Citizen_elah posted a related solution a while back: 
  
 http://devcentral.f5.com/Default.aspx?tabid=53&amp;forumid=5&amp;tpage=1&amp;view=topic&amp;postid=31347

when DNS_REQUEST {  
    if { [IP::addr [IP::client_addr]/24 equals "10.10.10.0"] } {  
      pool internal_pool  
    } else { pool external_pool }  
  }

Else, can you post the iRule you tested and the error you received when trying to save it?
