CirrostratusGTM hands out private IP addresses, need it to hand out public/translated IPs
NimbostratusIf you have https on the front end and 8080 on the back end servers, that implies that you are load balancing with what? F5 LTM? If so then the LTM is the one who is doing the health checks against the back end servers on 8080, and via iQuery will communicate to the GTM if any of them are down. Unless I am missing something. If you wanted the GTM to directly query the back end servers, does it have a route to their private IPs?
John_Heyer_1508In this case the servers were in a remote data center managed thru a partner, and there was no LTM. The servers ran Apache Proxy on port 443 were being accessed via NAT translations on a Cisco ASA firewall. 8080 was the app port, and was not exposed to internet. The GTM had access to the server private IPs via VPN.
But all moot now since the data center got an LTM in 2016 and then was retired in 2017.
