i am pretty new to IIS and ARR. i have 3 iis servers.
server 1 is running ARR and loadbalancing to the other two, with roundrobin, the loadbalancing works.
server 2-3 is running just ISS and the website
the website is a warehouse application so the application service on server 1 is contacting the ERP system to get data about I.E. articles.
When they just browse the website everything works, but when they want to get data from the ERP system it takes a long time.
But if I access server 1 locally it works perfekt, it´s only when i access server 1 via the DNS-record for ARR, throu the loadbalancing, it takes a long time to get data from the ERP system.

It is not sure this issue come from network side or IIS side. So please enable the failed request tracing and compare the time taken between local and remote dns mode. You could check the time taken in IIS failed request tracing log:

You could start with the front-end server. If the log display a low performance from backend server. Then you could start the tracing for backend.
