GTM Design For External DNS Queries

Hello,

 

I'm a little bit confused here as I'm setting up my upcoming project design which includes 2 boxes with GTM and LTM modules each, and each box will be located in a site (SITE A, SITEB),GTM will be handling the external DNS queries for a specific domain name (),

 

First is it possible configure a private IP on the GTM and NAT it with a public IP on our firewall,

 

So the DNS flow for my design is as the following:-

 

Internet Client --->External DNS (ISP DNS)-->Firewall--->GTM--->LTM--->VS

 

What should be done from the external DNS side, should the ISP just delegate the DNS queries matching the to the public IP configured on our firewall which will traverse all the DNS queries to our GTM,

 

Waiting for your recommendations

 

Thanks :)

 

  • Hello,

     

    what about the A record ip address of the Ns gtm1 is it the ip address of the listener configured on the GTM or is it the self ip address of the GTM?

     

    Also i have another question when doing the same delegation from the external DNS (Internet side) the delegation configuration will be as you stated the following:-

     

    ns1.gtm.example.com A X.X.X.X wip.example.com NS ns1.gtm.example.com

     

    Here the X.X.X.X Ip address will be the piblic ip address of the GTM to be natted on the firewall or what?regardless if its the listener or the self ip of the GTM.

     

    Hope you can help me

     

    Thank you..
