Hello Ma'Moun. Service graphs are applied via a contract relationship to an EPG. So, if I understand your question correctly, you would not need a new EPG for your server. You would apply a contract to its original EPG that included a service-graph that defines your service (maybe a Firewall or a Load Balancer). In the service graph you would have also configured PBR as per your environment.
