GTM should discover them no matter what the IP's are if the servers are communicating effectively. Is your monitor for the server bigip? If not, it needs to be if discover is desired. Personally, I like to control everything, so I manually edit GTM. To verify iQuery, go to the command line of the GTM and run this command:

 

 

iqdump LTM IP Address

 

 

If you don't see traffic updating every 30s (default), or you get an error, then iquery is not working correctly.

 

 

If iQuery isn't working, you might need to exchange certs, install the GTM's version of big3d, or both.

 

 

bigip_add LTM IP Address

 

big3d_install LTM IP Address

 

 

To add VS manuall, go to Data Centers->Servers and click on your BigIP

 

Click the Virtual Server Tab, then click add

 

 

Here I would put in only the real IP in the address field, leave off the translation. Also, I don't use the monitor at the virtual server level since I get the status from iquery.
