How to configure F5 as a reverse proxy

Hi mohammadhuq ,

First, as your external site will be running on https, you need to do SSL offloading on the F5 vServer. For this, you need to have CA signed certificate for your FQDN i.e. abc.com and you need to configure client ssl profile which will have this certificate & it’s associated key and at the end, this client-ssl profile will be mapped to the vServer.

With this, all the incoming requests from the client to the F5 will be encrypted. F5 vServer will decrypt it and then forward request to the backend app servers. 

For redirecting requests based on the URI, you can achieve this requirement using iRule as well as LTM policies.

Below is one sample iRule which is for your use case.

when HTTP_REQUEST {
  if { [HTTP::uri] starts_with "/sales" }{
    pool pool-sales
  } elseif { [HTTP::uri] starts_with "/marketing" }{
    pool pool-marketing
  } 
} 

 There are some other important settings on the vServer that you need to consider.

1. SNAT settings 

2. SSL Profiles

Hope it helps!
