Hi,

 

thanks for your swift response.

 

normally if I am creating a DNS record that needs publishing to internet and is required internally, I use an IRULE in gtm W-IP that basically does that job for me. However, I need gtm pools and their relevant Virtual servers etc.

 

as this service is not required on LTM and I just need a DNS record, wonder if there's a way of doing this either in DNZ ZONErunner or WIDE-IP etc to get this done without creating any LTM virtual servers.

 

Let me know if you any further explanation?

Hum, nope?!? 

GTM can add 3rd part servers on it.

Doing this, you'll lose LTM metrics from servers, because LTM is not there :)

But you can run GTM with other server and monitors.

 

For example, I can work with GTM and a generic FW that lays all of my HTTP services, etc.

I don't need to move FW behind LTM nor change all my infra. Because DNS is just a name resolver and I don't need to traverse it as well.

But it make sense to monitor the generic host virtual server to give me availabity or disable "Verify Member Availability" on pool to ignore available status.

 

Make it sense?

 

Regards.
