GTM QUERY: WIDE-IP

Hi Team,

 

For now we have existing LTM, where the VIP for the VS's are into Private IP addressing range, which in turn is NATTED into our firewall and added into the External LDNS server( Windows Server).

 

Now as part of the plan, we are introducing GTM into our Infrastructure, where Our GTM will act as the Secondary authoritative server to existing LDNS server.

 

Query:

 

  1. Lets say we are creating Wild-IP's against specific FQDN, which in turn associated with a pool, consisting of two Virtual-servers hosted into some BIG-IP systems existing in two different Data-Centers. And as I mentioned, we got Private IP's as the VIP into the Virtual-Server,will it work ? Or do we need to configure the VIP's as the Public IP ?

Thanks and Regards PZ

 

  • PZ,

     

    Yes that will work. When creating server and virtual server objects in GTM configuration the address field is the public NAT address (this is what GTM will use to answer DNS queries) and the translation field is the private/real address of the LTM and virtual servers.

     

  • Hi Parveez,

     

    In short you can use tmsh CLI for this as below..

     

    modify server virtual-servers add { x_y.f5.com-vip-443 { destination :0 translation-address translation-port 443 } }
