GTM and Public ISP
Hello,
I have not seen or played with GTM's so excuse the very likely daft questions !
so I have public facing web servers. currently they get resolved by public DNS to an IP, that IP hits our firewall and we NAT that IP to the inside IP of the application. Marvellous !, if a little basic.
So, we are buying a GTM (there will be more than one DC very soon running the same apps)
so I have an app say;
thisapp.thisdomain.com resolves via public DNS to public.public.public.public which goes to a particular DC.
I have seen stuff about adding a CNAME to our DNS (I am assuming public!) and also to add NS records. I guess the GTM will need an IP in the public range that can respond to queries from public DNS's.
I am not completely clear on what I need to do from an ISP perspective, tell 'em to set up cnames, additonal NS records etc
If someone has done this before I would be eternally grateful for a set of steps/instructions that perhaps even I could follow !
Thank you in advance,
George
