EGW external deployment

Product/components used and version/fix level:

WM 10.15. EGW & Mediator both as APIGateway components

Detailed explanation of the problem:

The EGW is deployed behind an F5, both are in internet. The EGW does acquire the auth token as a reverse proxy, but has no other configurations, everything is handled by the F5.
Now the Mediator (also an APIGateway) is in the DMZ.
Afterwards Integration servers are in the intranet.

I am trying to understand what purpose the EGW serves in this configuration and if it potentially could be replaced by any other reverse proxy, that would acquire the token. This is a hypothetical question, not supporting any planned changed, just for understanding the current deployment.

Question related to a free trial, or to a production (customer) instance?

Production environment.

Thank you for any answers.

A review of the info in the “webMethods API Gateway Administration” may help address your query.

Version 10.7 docs also included “API Gateway Configuration” which has diagrams and additional descriptions. I think that doc has been merged/rewritten and looks to be in the administration doc now.
