application

So I have a router as facing to the outside world. I have 3 application servers and a database server. All these servers are behind router. Now we are trying to configure the firewall between outside world and router. All servers use Redhat linux. What all precautions , steps I have to carry so that firewall configuration won't create any issue when we restart our application? It would be nice if experienced users help in this case.
