NimbostratusGTM placement for public DNS
Hi,
I got my hands on a GTM with version 9.4.5, which I want to use as a public DNS for jy domains. I have also bought a LTM which I will use as a reverse proxy for my webservers.
What i cannot find any info on is: where do jou place the GTM? I am a F5 novice. My intended setup:
Internet - firewall - gtm (dns) - ltm (rev.proxy) - firewall - servers
`
Is this correct? Does traffic actually flow through the gtm?? Or should this be:
`Internet - firewall - gtm (dns)
- ltm (rev. Proxy) - firewall - servers
What is the best way to go forward here? Any help is welcome!
Thanks, Marcel

I don't know what all of the options are pertaining to GTM and how granular it can get. For example, could be licensed for gtmd but not ZoneRunner (named). For our GTMs, we only have one line item in the active modules license section:
Global Traffic Manager Module(Perpetual)
MarcelNL_153054Ok, so this is the product info on my GTM... Looks like it only has the base licence. Reactivation went fine. Not sure why it does not have DNS listeners and Zonemanager.
Maybe because it is a "LIMITED" so it only does IP load balancing? In that case I bought an overly-expensive switch 😞

Even weirder:
The "named" service is running!
(While the "radvd" service is down because it is "not licenced", so licencing is maybe not the issue here?)

Yeah, I don't see anything GTM related in this license file.
You may have some local load balancing features with it based on that license though. What does the license look like your other BIG-IP appliance (the LTM)?
- Cory_50405
I believe you'll find named running on every BIG-IP appliance whether or not they are licensed for GTM. All of our LTMs and Enterprise Managers also have it.

Ok it seems gtmd is not present, nor is zrg. Maybe this GTM is not running as a GTM?

Well, it's a BIG-IP appliance. What makes it a GTM is a license. You could turn it into an LTM or APM or whatever else based on a license.
Yes, if it were licensed for GTM you'd definitely have gtmd and zrd.
- MarcelNL_153054
Argh. You beat me to it :-) That is bad news.
The LTM has a base licence with rev.proxy and 100 SSL
