NimbostratusHow to setup DNS resolution on GTM
Hi All, I know this may sound simple but I'm having a mind-block on how to setup the gtm to act as a DNS server. I've created two pairs of GTMs, each pair being HA sync'd and all four running gtm sy...
If you've added your LTMs into the GTMs as servers you should then be able to start creating pools for your wideIPs using the virtual server contained on your LTM "server"(GTM context) provided you have checked auto discover. You then associated your pools with the appropriate wideIPs. If your GTM will be hosting the whole zone that your wideIPs live in you will probably also need to either setup the zone in ZoneRunner or use an off box DNS server that will be used for a DNS-Express zone to act as an authoritative slave for. Below are some links to some helpful information.

NimbostratusThanks Brad, I can see the ability to create a wideIP and add the LTM VIPs, however the IP addresses of the LTM VIPs are all private addresses and I don't want the GTM to forward traffic. I need to GTM to act as a DNS resolver (authoritative server) for our Public address space and I'm having a problem seeing how I build this as I can't see where I match up a Public IP address with a URL. The intention is not to use an internal DNS server to provide this, rather have the GTM cluster work as the authoritative DNS server.
