There is a portal which is currently accessible through intranet. Say, the request comes first to F5 (internal load balancer of the organization) then F5 to portal connection is established. Now, due to need, want to publish the portal in internet. Flow will be same like the request will land to F5 then F5 will forward request to the portal. Can anyone let me know what could be approaches to do this and what will be the best approach in such cases with minimal change.
