GTM persistence/setup

i have an web app that cant accept x-forwarder-for in the header and they need to see source-ip for security logging. we have decided to use GTM to get around the issue. i have setup in my DNS servers a sub-domain that i forward to the F5 GTM.

 

Example - app calls apples.example.com.. i CNAME it to apples.fruits.example.com which is a WideIP on the GTM. i also have round robin persistence setup so they stick to one web server for the default one hour (3600s).. their two webservers are setup as generic hosts in the GTM in two separate pools.

 

when i look at the gtm persistence records, my requests seem to come from the DNS servers, arent these supposed to look like they are coming from the client??? we have two windows machines defined on our clients and i dont want all requests to only go to one GTM pool..

 

ideas?

  • Hello, in a public DNS environment you will never see client IP addresses on GTM, but only ISP DNS resolvers used by clients. So you will always persist on DNS resolver source IP.
