Hi  ,

Does your backend/internal URLs are pointed to IP addresses of backend server or LB IPs? If yes, then you can simply use the FQDN type node in the pool and add backend FQDN node as a pool member. Just need to make sure that those FQDNs should resolve IPs on the DMZ F5.

 

If backend/internal URLs are not pointed to the IP addresses of backend server or LB IPs and you want DMZ F5 to send server side request to those internal URLs, you can try rewrite profiles.
